Today I'm excited to talk about PowerOfThree v0.1.3, a library that bridges the gap between Elixir applications and business intelligence tools. Our tagline is 'Start with everything. Keep what performs. Pre-aggregate what matters' - and by the end of this talk, you'll understand exactly what that means." + +**Energy:** High, enthusiastic opening + +--- + +## Slide 2: About Me (1 min) + +**Customize this section with your own background** + +**Suggested structure:** +- Your name and role +- How long you've worked with Elixir +- What problem led you to build PowerOfThree +- Any relevant open source contributions + +**Keep it brief** - audience wants to hear about the tool, not your life story + +--- + +## Slide 3: The Problem (3 min) + +**Say:** +"Let's start with a common scenario. You've built a great Elixir application with Phoenix and Ecto. Your schemas are well-defined, your business logic is clean. But then your business stakeholders come to you and say 'We need dashboards. We need analytics. We need to understand our data.' + +So what do you do? The traditional approach is painful - you set up an ETL pipeline, move data to a warehouse, write a bunch of SQL queries, hook up a BI tool. But here's the problem..." + +**Pause for effect** + +"...you're now maintaining TWO definitions of your data model. Your Ecto schemas in Elixir, and your analytics definitions in SQL or YAML. When your schema changes, you have to remember to update both. There's no compile-time validation. Schema drift becomes inevitable." + +**Ask the audience:** +"Show of hands - who has dealt with schema drift between their application and their analytics layer?" + +**Expect some hands** + +"Right. It's a universal problem. And that's exactly what PowerOfThree solves." + +--- + +## Slide 4: Enter Cube.js (3 min) + +**Say:** +"Before I show you the solution, I need to briefly explain Cube.js, because not everyone here may be familiar with it." + +"Think of Cube.js as GraphQL for analytics. You define your metrics once - your dimensions, your measures - and then you can query them from anywhere: REST API, GraphQL, even as a SQL interface that BI tools can connect to." + +**Show the code example on slide** + +"Here's a simple cube definition. We define a cube called 'orders', we specify dimensions like customer email and status, measures like count and total revenue. Once defined, Cube.js handles all the query optimization, caching, and pre-aggregations." + +**Key point:** +"The magic of Cube.js is pre-aggregations. Think materialized views on steroids. A 5-second query can become 50 milliseconds. It's genuinely impressive technology." + +**Transition:** +"But here's the rub - Cube.js definitions are in YAML or JavaScript. Your Elixir schemas are in... Elixir. That's where PowerOfThree comes in." + +--- + +## Slide 5: PowerOfThree Solution (4 min) + +**Say:** +"This is the heart of PowerOfThree. Look at this code." + +**Read through the schema definition** + +"Standard Ecto schema, nothing special. But then look at this one line..." + +**Point to cube line** + +"`cube :orders, sql_table: "orders"` - that's literally it. One line. And at compile-time, PowerOfThree introspects your Ecto schema and generates a complete Cube.js configuration." + +**Explain what happens:** +1. "When you compile, PowerOfThree looks at your schema fields" +2. "It infers which fields should be dimensions - strings, booleans, timestamps" +3. "It infers which should be measures - counts, sums for numeric fields" +4. "It generates the YAML files Cube.js needs" +5. "And it shows you exactly what it generated" + +**Key benefit:** +"Single source of truth. Your Ecto schema IS your analytics definition. Change your schema, your analytics updates automatically. Compile-time validation means you catch errors immediately, not in production." + +--- + +## Slide 6: Live Demo - The Barbell (2 min) + +**Say:** +"Now I want to show you something fun. When you compile a project using PowerOfThree, you see this..." + +**If you can do a live demo, do it. Otherwise, describe it:** + +"You see this ASCII art barbell. On the left is a hexagonal plate labeled 'Ecto Macro Elixir' - that's the Elixir side. On the right is a 3D cube labeled 'CUBE' - that's Cube.js. And the bar connecting them represents PowerOfThree." + +**Pause** + +"It's an Olympic weightlifting barbell, because PowerOfThree helps you lift heavy analytics workloads. The visual metaphor is about strength, performance, and proper technique - which in our case means type safety and the semantic layer." + +"The barbell has nice details too - knurling pattern on the bar, collar clips, proper 3D perspective on the cube. All rendered in ANSI colors." + +**Lighter tone:** +"Developer experience matters. Making people smile when they see a compile message? That's worth doing." + +--- + +## Slide 7: What Gets Auto-Generated (3 min) + +**Say:** +"Let me show you concretely what PowerOfThree generates from a real schema." + +**Walk through the schema:** +- "Four regular fields: email, amount, status, count" +- "Plus timestamps macro which adds inserted_at and updated_at" + +**Then show what's generated:** + +"For dimensions, PowerOfThree generates one for each string field, plus the timestamp fields. That's customer_email, status, inserted_at, updated_at." + +"For measures, it always generates count - every cube needs count. Then for numeric fields, it generates sums and count_distinct. So we get total_amount_sum for revenue, and item_count_sum and item_count_distinct." + +**Important point:** +"No manual YAML writing. Zero. This all happens automatically. And if you compile and realize you don't need something? Just add your own cube block and only include what you want. That's the 'Scaffold → Refine → Own' workflow we'll talk about next." + +--- + +## Slide 8: v0.1.3 Client-Side Granularity (4 min) + +**Say:** +"Now let me talk about the headline feature of v0.1.3 - client-side granularity. This is actually a breaking change, but it's a really important one." + +**Show the old way:** +"In version 0.1.2, whenever PowerOfThree saw a timestamp field, it generated SIXTEEN dimensions. One for each granularity - second, minute, hour, day, week, month, quarter, year. Times two for inserted_at and updated_at. Sixteen dimensions just for timestamps!" + +**Pause for effect** + +"That's... a lot. Your schemas got cluttered. Your YAML files got huge. And it's not even how Cube.js is designed to work." + +**Show the new way:** +"In v0.1.3, we generate just TWO simple time dimensions. That's it. But you still get all 8 granularities!" + +**Explain:** +"The difference is WHERE you specify granularity. In the old way, it was at dimension definition time. In the new way, it's at query time using Cube.js's native date_trunc function." + +**Show the example query if you have time** + +**Benefits:** +1. "Cleaner schemas - 2 dimensions instead of 16" +2. "40% smaller YAML files - we measured this" +3. "More flexible - choose granularity when querying" +4. "Follows Cube.js best practices" + +--- + +## Slide 9: Why Client-Side Granularity (2 min) + +**Say:** +"Let me drive this point home with a concrete example of how you'd actually query this." + +**Read through the JSON query:** +"You have your time dimension, inserted_at. And you specify granularity right here in the query - month. Need daily data instead? Change it to 'day'. Need quarterly? Change it to 'quarter'." + +**Key insight:** +"This is more flexible than having 16 pre-defined dimensions because you're not locked into dimension names. The query structure is cleaner. And Cube.js handles the date_trunc SQL generation efficiently." + +**Transition:** +"This might seem like a small change, but it represents a philosophical shift - trust the framework. Don't fight Cube.js's design, embrace it. That's what v0.1.3 is about." + +--- + +## Slide 10: Compile-Time Type Safety (3 min) + +**Say:** +"One of PowerOfThree's core strengths is compile-time validation. Let me show you what I mean." + +**First example:** +"You define a dimension called customer_email - PowerOfThree checks your schema, sees that field exists, validates it. Green light." + +"You typo it as 'customr_email' - compile error. Immediate feedback." + +**Second example:** +"You create a sum measure for total_amount, which is numeric. That works. You try to sum 'status', which is a string - compile error. You can't sum strings." + +**The value:** +"This is HUGE for refactoring. Let's say you rename a field in your schema. Without PowerOfThree, your analytics queries would silently break at runtime - or worse, in production. With PowerOfThree, you get a compile error immediately. You fix it before it ships." + +**Ask rhetorically:** +"How much is it worth to catch a bug at compile-time versus in production? That's PowerOfThree's value proposition." + +--- + +## Slide 11: Scaffold → Refine → Own (4 min) + +**Say:** +"Now I want to talk about the workflow PowerOfThree enables. We call it Scaffold → Refine → Own." + +**Step 1: Scaffold** +"You start with the simplest possible definition - one line. `cube :orders, sql_table: "orders"`. No block, no configuration, just that." + +**Step 2: See the output** +"You compile, and PowerOfThree shows you EXACTLY what it generated. All the dimensions, all the measures, fully formatted, syntax-highlighted. This is your scaffold." + +**Step 3: Refine** +"Now you look at that output and ask: What do I actually need? Maybe you don't need ALL those dimensions. Maybe you want to rename some measures to match your business terminology. So you copy-paste the generated code, delete what you don't need, customize the rest." + +**Show the refined example:** +"See how we renamed 'count' to 'total_orders' and 'total_amount_sum' to just 'revenue'? More readable. More business-friendly. And we added a new measure - unique_customers - that's business logic PowerOfThree couldn't infer." + +**Step 4: Own it** +"Now it's YOUR definition. You own it. You maintain it. But you started from a working scaffold instead of a blank file." + +**Key message:** +"This workflow means you're productive immediately, but not locked into auto-generation. Start with everything, keep what performs, pre-aggregate what matters." + +--- + +## Slide 12: Real-World Example (2 min) + +**Say:** +"Let me show you a real-world example - e-commerce order analytics." + +**Walk through the schema briefly:** +"We have an Order schema with email, amounts, tax, status, a customer reference, and timestamps. Pretty standard e-commerce stuff." + +**Show what's generated:** +"PowerOfThree auto-generates 6 dimensions and 7 measures. That's a fully functional analytics cube in one line of code." + +**The impact:** +"In a real project, you might have 20-30 schemas. That's 20-30 cubes you can scaffold immediately. Your analytics layer is 80% done in minutes, not weeks. Then you refine with business logic." + +**Transition:** +"That's the power of auto-generation backed by type safety." + +--- + +## Slide 13: Architecture Deep-Dive (3 min) + +**Say:** +"For the programmers in the room, let me briefly show you how this actually works under the hood." + +**Walk through the flow:** + +1. "It all starts at `mix compile`. PowerOfThree hooks into the compilation process." + +2. "When your module uses PowerOfThree, it runs the `__using__` macro." + +3. "This macro extracts your Ecto schema metadata - all the field names and types." + +4. "Then it infers dimensions and measures based on type rules. Strings become dimensions. Integers get sum and count_distinct measures. Etc." + +5. "It generates the cube DSL code - the stuff you see in the output." + +6. "It validates everything against your schema - catching typos and type errors." + +7. "It outputs YAML files to model/cubes/ that Cube.js can read." + +8. "And it shows you that syntax-highlighted preview." + +**The key insight:** +"All of this happens at COMPILE-TIME. There is zero runtime overhead. Your application doesn't even know PowerOfThree exists at runtime. It's pure metaprogramming." + +**For Elixir devs:** +"If you've ever wondered what you can do with Elixir macros, this is a great example. Compile-time code generation with validation." + +--- + +## Slide 14: Code Injection Protection (2 min) + +**Say:** +"Security is always important, so PowerOfThree includes code injection protection." + +**Good example:** +"If you write a custom SQL expression that uses field names and standard SQL functions, that's fine. PowerOfThree validates it and lets it through." + +**Bad example:** +"If you try to inject malicious SQL - like this semicolon and DROP TABLE - PowerOfThree detects it and logs a warning." + +**What it checks:** +- "SQL injection patterns" +- "Dangerous keywords like DROP, DELETE, TRUNCATE" +- "Invalid field references" +- "Type mismatches" + +**Caveat:** +"This isn't foolproof - you can still write buggy SQL - but it catches obvious attacks and common mistakes. Defense in depth." + +--- + +## Slide 15: Explorer Integration (3 min) + +**Say:** +"One of the cool integrations in PowerOfThree is with Explorer DataFrames. For those who don't know, Explorer is Elixir's answer to Pandas or Polars - it's for data science and analysis." + +**Show the code:** + +"You define your query as a map - measures, dimensions, time dimensions with granularity. Then you call `PowerOfThree.query(Order, query)` and you get back an Explorer DataFrame." + +**The power:** +"Now you can use all of Explorer's functions - filter, group, arrange, join. You're combining Cube.js's aggregation power with Elixir's data manipulation." + +**Use case:** +"Imagine you're building a Phoenix LiveView dashboard. You query Cube.js for aggregated data, get it as a DataFrame, manipulate it in Elixir, and render it in LiveView. All in one language, all type-safe, all performant." + +**This is unique:** +"You can't do this in JavaScript. You can't do this in Python (easily). This is the Elixir advantage - first-class data science tools that integrate seamlessly." + +--- + +## Slide 16: Deployment Architecture (2 min) + +**Say:** +"Let me quickly cover how this works in a real deployment." + +**Development:** +"On your laptop, you run `mix compile`, which generates YAML files. You point a local Cube.js instance (running in Docker) at those files. You iterate quickly." + +**Production:** +"In production, your Elixir app generates YAML files - same process. Those files are deployed to a Cube.js cluster running on Kubernetes." + +**The Cube.js cluster has three layers:** +1. "API pods that handle queries" +2. "Refresh workers that build pre-aggregations" +3. "Cubestore for columnar storage" + +**PowerOfThree's role:** +"PowerOfThree handles the 'schema definition' part. It doesn't run in production. It's a build-time tool. Your YAML files are what ship." + +**Separation of concerns:** +"Your Elixir app serves requests. Cube.js handles analytics. They're separate concerns, properly isolated." + +--- + +## Slide 17: Generated YAML Files (2 min) + +**Say:** +"What do those YAML files actually look like? Let me show you." + +**Walk through the YAML:** +"Pretty straightforward. You have cube name, sql_table, then arrays of dimensions and measures." + +"Each dimension has a name, type, and SQL expression. Notice the metadata? That's PowerOfThree adding extra information for debugging. If something goes wrong, you can trace it back to the Ecto field." + +"Measures are similar - name, type, SQL." + +**The point:** +"This is the contract between your Elixir app and Cube.js. And it's auto-generated from your Ecto schemas. Single source of truth." + +--- + +## Slide 18: Test Coverage (1 min) + +**Say:** +"Quick note on reliability - PowerOfThree has 290 tests with 90% coverage." + +**What we test:** +- "Every Ecto type - strings, integers, floats, datetimes, you name it" +- "Type safety - all the validation logic" +- "YAML generation - making sure output is correct" +- "Integration - actual Cube.js queries" + +**The message:** +"This isn't a toy library. It's production-ready. We take testing seriously." + +--- + +## Slide 19: Performance & Pre-aggregations (2 min) + +**Say:** +"I mentioned pre-aggregations earlier. Let me expand on that because it's crucial for performance." + +**What are pre-aggregations:** +"Think of them as materialized views that Cube.js automatically maintains. You define which measures and dimensions to pre-compute, and Cube.js handles the rest." + +**Show the code:** +"Here's a pre-aggregation definition in PowerOfThree. We're saying: pre-compute count and revenue, broken down by status and inserted_at by day. Refresh every hour." + +**The impact:** +"A query that normally takes 5 seconds scanning millions of rows? Now it's 50 milliseconds reading from the pre-aggregation. 100x speedup." + +**The beauty:** +"PowerOfThree lets you define these in Elixir, alongside your cube definition. Everything in one place." + +--- + +## Slide 20: Before and After (2 min) + +**Say:** +"Let me show you a stark before-and-after comparison." + +**Before:** +"You're writing YAML by hand. This is for a simple cube with two dimensions and one measure. It's 15-20 lines. Multiply that by 30 schemas? You're writing hundreds of lines of YAML." + +**After:** +"One line. `cube :orders, sql_table: "orders"`. Done." + +**Do the math:** +"40+ lines of YAML becomes 1 line of Elixir. And more importantly - that one line is type-safe, validated at compile-time, and automatically stays in sync with your schema." + +**The productivity gain:** +"I'm not exaggerating when I say PowerOfThree can save you weeks of work on a medium-sized project." + +--- + +## Slide 21: The Philosophy (2 min) + +**Say:** +"I want to take a moment to talk about the philosophy behind PowerOfThree, because it informs the design." + +**Start with everything:** +"When you're starting out, you don't know what analytics you'll need. So generate everything. All dimensions, all measures. Get immediate value." + +**Keep what performs:** +"Then you monitor your query patterns. Which dimensions are actually being used? Which measures are hot? Keep those. Remove the rest." + +**Pre-aggregate what matters:** +"For the hot paths, add pre-aggregations. For cold paths, on-demand queries are fine." + +**This is iterative:** +"You're not trying to design the perfect schema up front. You're iterating based on real usage. PowerOfThree enables this workflow by making it cheap to change your mind." + +--- + +## Slide 22: Roadmap (1 min) + +**Say:** +"Looking ahead, here's what's on the roadmap for PowerOfThree." + +**Quickly run through the list:** +- Schema prefix support for multi-tenancy +- Automatic joins based on Ecto associations +- Pre-aggregation improvements +- CI integration helpers +- And more + +**Community:** +"This is open source. We welcome contributions, feature requests, bug reports. If you have ideas, open an issue on GitHub." + +--- + +## Slide 23: Why Elixir + Cube.js (3 min) + +**Say:** +"Let me step back and answer the question: why this combination? Why Elixir and Cube.js?" + +**Elixir strengths:** +"Elixir gives you compile-time metaprogramming - that's what makes PowerOfThree possible. Type safety through Ecto. The actor model for real-time features. Phoenix LiveView for reactive dashboards." + +**Cube.js strengths:** +"Cube.js gives you a battle-tested analytics layer. Pre-aggregations that actually work. Support for multiple databases. Integrations with every major BI tool." + +**Together:** +"PowerOfThree is the bridge. It takes Elixir's compile-time strengths and applies them to Cube.js's runtime capabilities. Best of both worlds." + +**This isn't either/or:** +"You're not choosing Elixir OR Cube.js. You're using both, and PowerOfThree makes them work together seamlessly." + +--- + +## Slide 24: Live Demo (5 min) + +**If you have time for a live demo, structure it like this:** + +1. **Show a simple schema** (30 sec) + - "Here's an Ecto schema with a few fields" + +2. **Add cube definition** (30 sec) + - "I add one line - cube :sales, sql_table: 'sales'" + +3. **Run mix compile** (1 min) + - "Let's compile and see what happens" + - Show the barbell output + - Show the generated code + +4. **Open iex** (2 min) + - "Now let's query this from iex" + - Show a simple query + - Show the DataFrame result + +5. **Show the YAML file** (1 min) + - "And here's the generated YAML that Cube.js consumes" + +**If no demo:** +Skip this slide and spend more time on other topics + +--- + +## Slide 25: Edge Cases (2 min) + +**Say:** +"Let me quickly cover some edge cases PowerOfThree handles well." + +**Multiple schemas, one table:** +"You can have different cube definitions pointing to the same table. Just use different cube names." + +**Custom SQL:** +"You can write custom SQL expressions. PowerOfThree validates them but doesn't restrict you." + +**Filters:** +"You can add filters to measures - like only counting premium customers who spent over $1000." + +**The design principle:** +"Auto-generation for common cases, customization for edge cases. You're never locked in." + +--- + +## Slide 26: Production Use Cases (2 min) + +**Say:** +"Where does PowerOfThree shine in production?" + +**Run through the list:** +1. "E-commerce - orders, customers, products" +2. "SaaS - user behavior, feature adoption, retention metrics" +3. "FinTech - transaction analysis, fraud detection" +4. "Healthcare - patient outcomes, resource utilization" +5. "Logistics - delivery metrics, route optimization" + +**Common pattern:** +"Any domain where you have Ecto schemas modeling your business data, and you need analytics on top of that data." + +**The sweet spot:** +"Especially valuable for teams that want BI tool integration - Tableau, Metabase, etc - but don't want to manually maintain analytics schemas." + +--- + +## Slide 27: Getting Started (1 min) + +**Say:** +"If you want to try PowerOfThree, getting started is simple." + +**Installation:** +"Add it to your mix.exs dependencies. Version 0.1.3 is the latest." + +**Basic setup:** +"In any module with an Ecto schema, add `use PowerOfThree` and define a cube." + +**Try it:** +"Compile and see the magic happen. The barbell, the generated code, everything." + +**Time investment:** +"You can have your first cube working in under 5 minutes." + +--- + +## Slide 28: Resources (1 min) + +**Say:** +"Here are some resources if you want to learn more." + +**Documentation:** +"Full docs on hex.pm, source on GitHub, examples in a separate repo." + +**Guides:** +"We have three main guides - a quick-start, a detailed auto-generation blog post, and a full analytics workflow guide." + +**Cube.js:** +"And if you're not familiar with Cube.js, their docs are excellent. Start there to understand the semantic layer concept." + +--- + +## Slide 29: Community (1 min) + +**Say:** +"PowerOfThree is open source under Apache 2.0." + +**We welcome:** +- Bug reports +- Feature requests +- Documentation improvements +- Code contributions +- Sharing your use cases + +**GitHub:** +"Everything happens on GitHub issues. Open, transparent, community-driven." + +--- + +## Slide 30: Key Takeaways (2 min) + +**Say:** +"Let me wrap up with the key takeaways from this talk." + +**Read through each point:** + +1. "One definition, two worlds - your Ecto schema becomes your analytics layer" +2. "Compile-time safety - catch errors before production" +3. "Auto-generation - start productive immediately" +4. "Client-side granularity - clean, flexible time dimensions" +5. "Scaffold → Refine → Own workflow" +6. "290 tests - production-ready reliability" + +**Final message:** +"PowerOfThree bridges the gap between your Elixir application and your analytics needs. It's about reducing friction, increasing productivity, and maintaining quality." + +--- + +## Slide 31: Questions (5-10 min) + +**Say:** +"Thank you for your attention! I'm happy to take questions." + +**Be prepared for:** + +- "Does this work with Postgres? MySQL?" + - Yes, Cube.js supports many databases + +- "What about Phoenix LiveView integration?" + - Works great, especially with Explorer DataFrames + +- "Can I customize the generated output?" + - Absolutely, that's the Refine step + +- "What's the performance overhead?" + - Zero runtime overhead, it's compile-time only + +- "Does this replace my BI tool?" + - No, it complements it. Cube.js sits between your DB and BI tools + +**Stay engaged, be enthusiastic!** + +--- + +## Bonus Slide: ASCII Art Story (If time permits) + +**Say:** +"Since we have a bit of extra time, let me tell you the quick story of the ASCII art." + +"We went through several design iterations. Started with a simple bar representation, then designed the hexagonal HEX plate for Ecto/Elixir on the left. Then the 3D isometric CUBE plate for Cube.js on the right." + +"We added realistic barbell details - the knurling pattern on the bar, collar clips to keep the plates in place. And we used ANSI colors - cyan, yellow, and magenta - to make it pop in the terminal." + +**Why it matters:** +"This represents attention to detail. Developer experience isn't just about APIs and docs. It's about the whole experience, including making your compile output something people enjoy seeing." + +"Small details compound. Happy developers are productive developers." + +--- + +## Bonus Slides: Advanced Topics (If time permits) + +### Meta-Programming Deep Dive + +**For a technical audience, show the actual macro code** + +"Here's simplified version of how the cube macro works..." + +"The key insight is that all schema information is available at compile-time through __schema__/1 and __schema__/2 functions that Ecto generates." + +### Join Support (Coming Soon) + +"One of the most requested features is automatic join generation..." + +### Performance Optimization Details + +"Let me show you the actual file size reduction we achieved..." + +--- + +## Closing Energy + +**End on a high note:** + +"Thank you all for listening! I hope you're as excited about PowerOfThree as I am. Try it out, let me know what you think, and happy coding!" + +**Make yourself available:** +"I'll be around after the talk if anyone wants to chat more about specific use cases or technical details." + +**Smile and be approachable!** + +--- + +## Time Management Guide + +**Total: 30-40 minutes** + +- Intro and Problem: 5 min +- Cube.js and Solution: 7 min +- Demo and Features: 8 min +- Workflow and Examples: 6 min +- Architecture and Advanced: 5 min +- Roadmap and Resources: 3 min +- Wrap-up: 2 min +- Q&A: 5-10 min + +**Buffer:** If running short, expand on: +- Live demo (add 5 min) +- More real-world examples (add 3 min) +- Advanced topics slides (add 5 min) + +**If running long, cut:** +- Some technical deep-dives +- Bonus slides +- Edge cases details + +**Practice timing beforehand!** From c349f22ec3be09fe805a169de6d7a30939b609c2 Mon Sep 17 00:00:00 2001 From: Igor O'sten Date: Wed, 24 Dec 2025 15:34:23 -0500 Subject: [PATCH 05/26] Update v0.1.3-release-talk.md --- docs/presentations/v0.1.3-release-talk.md | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/docs/presentations/v0.1.3-release-talk.md b/docs/presentations/v0.1.3-release-talk.md index 7601bce..70c790d 100644 --- a/docs/presentations/v0.1.3-release-talk.md +++ b/docs/presentations/v0.1.3-release-talk.md @@ -86,14 +86,14 @@ end **Run `mix compile`:** ``` -# ________ ________ -# / \ / /| -# / Ecto \ / CUBE / | -# / \ || ||/_______/ | -# | Macro ||===<<<>>>===<<<<-->>>>>==========<<<-->>>|| ... | | -# \ / || || | | / -# \ Elixir / | CUBE | / -# \________/ |_______|/ +# ________ ________ +# / \ / /| +# / Ecto \ / CUBE / | +# / \|| ||/_______/ | +# | Macro ||===<<--->>==<<--->>=======<<--->>==<<--->>==||| ... | | +# \ /|| ||| | / +# \ Elixir / | CUBE | / +# \________/ |_______|/ # # PowerOfThree: Connecting Elixir (HEX) ←→ Cube.js (CUBE) ``` From 0032c3f1f7ec8b956306f3b723d330ccb9a5f9c6 Mon Sep 17 00:00:00 2001 From: Egor O'Sten Date: Wed, 24 Dec 2025 15:40:02 -0500 Subject: [PATCH 06/26] bar detail --- lib/power_of_three.ex | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/power_of_three.ex b/lib/power_of_three.ex index f1831e4..eb6cae2 100644 --- a/lib/power_of_three.ex +++ b/lib/power_of_three.ex @@ -329,7 +329,7 @@ defmodule PowerOfThree do "# / \\ / /|", "# / Ecto \\ / CUBE / |", "# / \\ #{ANSI.yellow()}||#{ANSI.cyan()} #{ANSI.yellow()}||#{ANSI.cyan()}/________/ |", -

Hourly pre-agg: 4.9M rows + - Daily pre-agg: ~200K rows (24x smaller) + - Arrow IPC must aggregate millions of rows in CubeStore + +2. **Aggregation Overhead**: + - Queries require `GROUP BY` and `SUM()` over hourly data + - Example: Monthly aggregation needs to sum ~720 hours per month + - CubeStore processes this directly without optimizations + +3. **No Query Cache**: + - Arrow IPC bypasses Cube.js query cache + - HTTP API benefits from cached intermediate results + - Hourly queries are more likely to be cached + +### Why HTTP API Wins with Hourly Pre-aggs + +1. **Cube.js Optimizations**: + - Query result caching + - Smarter query planning + - Possible pre-computed rollups + +2. **Less Data Transfer**: + -

- Daily pre-agg: ~200K rows (24x smaller) - - Arrow IPC must aggregate millions of rows in CubeStore - -2. **Aggregation Overhead**: - - Queries require `GROUP BY` and `SUM()` over hourly data - - Example: Monthly aggregation needs to sum ~720 hours per month - - CubeStore processes this directly without optimizations - -3. **No Query Cache**: - - Arrow IPC bypasses Cube.js query cache - - HTTP API benefits from cached intermediate results - - Hourly queries are more likely to be cached - -### Why HTTP API Wins with Hourly Pre-aggs - -1. **Cube.js Optimizations**: - - Query result caching - - Smarter query planning - - Possible pre-computed rollups - -2. **Less Data Transfer**: - - HTTP returns JSON (smaller for numeric data) - - Arrow IPC transfers full columnar batches - -3. **Better for Fine-Grained Data**: - - Designed to work with large pre-agg tables - - Optimized query execution path - -## Recommendations - -### Use Arrow IPC When: - -✅ **Pre-aggregation granularity is coarse** (daily, weekly, monthly) -✅ **Pre-agg table is relatively small** (< 500K rows) -✅ **Query needs many measures** (columnar format advantage) -✅ **Fresh data is critical** (no caching needed) -

Pre-Aggregations (Opt-In) + +## Overview +- Adds an opt-in default pre-aggregation for auto-generated cubes when `updated_at` exists. +- Prints the pre-aggregation block in the auto-generated Elixir snippet. +- Enforces a consistent pre-aggregation name suffix: `_automatic_for_the_people`. +- Adds Cube HTTP integration coverage across date granularities/ranges. +- Documents the new flag in README and quick reference. + +## What’s New +- `default_pre_aggregation: true` generates a single rollup pre-aggregation. +- Rollup defaults: + - `external: true` + - `time_dimension: :updated_at` + - `granularity: :hour` + - `refresh_key: SELECT MAX(id) FROM ` + - `build_range_start/end` based on `NOW()` + - excludes `updated_at` and `inserted_at` from dimensions +- Printed cube snippet now shows

+# Default Pre-Aggregations in PowerOfThree + +PowerOfThree already auto-generates dimensions and measures for your Ecto schemas. This release adds an opt-in default pre-aggregation so new cubes are fast by construction, without extra DSL work. + +## Why This Matters + +Pre-aggregations are Cube’s superpower. They turn large scans into fast lookups. The new default pre-aggregation gives you a reasonable rollup right after `mix compile`, and you can still refine it as your needs evolve. + +## How to Enable + +```elixir +cube :orders, default_pre_aggregation: true +``` + +### Requirements + +- `updated_at` must exist (usually via `timestamps()`). +- The cube must have measures and dimensions. + +## What Gets Generated + +When enabled and `updated_at` is present, PowerOfThree adds a single rollup: + +- `name`: `_automatic_for_the_people` +- `external: true` +- `time_dimension: :updated_at` +- `granularity: :hour` +- `refresh_key`: `SELECT MAX(id) FROM ` +- `build_range_start/end`: `NOW() - INTERVAL '1 year'` → `NOW()` +- `dimensions`: all default dimensions except `updated_at` and `inserted_at` + +### Example Output (Elixir Snippet) + +```elixir +cube :orders, + sql_table: "public.order", + default_pre_aggregation: true, + pre_aggregations: [ + %{ + name: :public_order_automatic_for_the_people, + type: :rollup, + external: true, + measures: [:count, :total_amount_sum], + dimensions: [:market_code, :brand_code], + time_dimension: :updated_at, + granularity: :hour, + refresh_key: %{sql: "SELECT MAX(id) FROM public.order"}, + build_range_start: %{sql: "SELECT NOW() - INTERVAL '1 year'"}, + build_range_end: %{sql: "SELECT NOW()"} + } + ] do + # dimensions and measures... +end +``` + +## How to Customize Later + +The generated pre-aggregation is just a starting point. You can: + +- Drop dimensions that don’t help query patterns. +- Remove heavy measures. +- Change granularity to day/week/month depending on the use case. +- Replace the refresh key with a more accurate watermark. + +## Summary + +This opt-in default pre-aggregation gives you a fast baseline without extra work. It keeps the scaffolding approach intact: generate, run fast, refine what matters.
