From 43123a290a73a2bf8674d22e611ad1d068a87608 Mon Sep 17 00:00:00 2001 From: Aleksandr Romanenko Date: Fri, 19 Jun 2026 14:00:59 +0200 Subject: [PATCH 01/17] feat(cubestore): dict-encoded string group keys for inline aggregate (wip, behind flag) Behind CUBESTORE_DICTIONARY_ENCODING (dev default currently ON - flip to false before merge). Adds DictionaryComparator + DictionaryGroupColumn to the sorted inline aggregate and routes dict schemas there via supported_type; String columns flow as Dictionary(Int32,Utf8) end-to-end (metastore as_arrow_field + CubeTable / CubeTableLogical schema). Measured on stend: inline/sorted ~10% faster, but hash/Linear ~60% slower (read-side cast_to_dictionary + df row fallback). WIP / not yet handled (only matters when flag ON): in-memory chunks stay Utf8 (schema mismatch), dict->string result serialization for non-aggregate SELECT, native dict parquet read to avoid the read cast, and hash-aggregate dict-awareness. --- rust/cubestore/cubestore/src/config/mod.rs | 10 + rust/cubestore/cubestore/src/metastore/mod.rs | 52 ++-- .../inline_aggregate/column_comparator.rs | 159 ++++++++++++ .../dictionary_group_column.rs | 139 +++++++++++ .../src/queryplanner/inline_aggregate/mod.rs | 66 +++-- .../inline_aggregate/sorted_group_values.rs | 233 +++++++++++++++++- .../cubestore/src/queryplanner/mod.rs | 9 +- .../cubestore/src/queryplanner/planning.rs | 6 +- .../src/queryplanner/query_executor.rs | 3 +- 9 files changed, 629 insertions(+), 48 deletions(-) create mode 100644 rust/cubestore/cubestore/src/queryplanner/inline_aggregate/dictionary_group_column.rs diff --git a/rust/cubestore/cubestore/src/config/mod.rs b/rust/cubestore/cubestore/src/config/mod.rs index 5cba4c1222959..602aa34c14294 100644 --- a/rust/cubestore/cubestore/src/config/mod.rs +++ b/rust/cubestore/cubestore/src/config/mod.rs @@ -585,6 +585,10 @@ pub trait ConfigObj: DIService { /// streaming split never drops rows (the first child is the low catch-all, the last /// the high one), and the legacy per-chunk path performed no such metadata check. fn repartition_check_overlapping_children(&self) -> bool; + /// Master gate for string dictionary-encoding work: reading string columns as + /// `DictionaryArray` and the dictionary-aware inline aggregate paths.

the only fork change is pub new_group_values (df branch cubestore-hash-aggregate-limit). WIP: the trim is planted during router planning but is NOT yet carried across the ClusterSend boundary to the worker's independent physical re-plan, so it does not engage at distributed execution yet.

Instead of a new proto, reuse the existing worker_sort_and_limit carry (already serialized across ClusterSend): when group_by_limit_factor > 0, resort_worker_subtree now wraps the worker partial hash aggregate in GroupByLimitAggregateExec (trim during aggregation, bounded O(factor*k) memory) instead of a SortExec over the full partial; the Sort above still orders the <= k surviving groups so the router's sort-preserving merge stays correct. group_by_limit_factor (CUBESTORE_GROUP_BY_LIMIT_FACTOR, default 2) is threaded router->worker via CubeQueryPlanner; 0 keeps the previous sort-then-trim. Verified on the production-dump stend: with factor>0 the worker EXPLAIN ANALYZE shows GroupByLimitAggregate (was LinearPartialAggregate) and results are identical. Value is bounded hash-table memory (OOM avoidance) on high-cardinality group-bys, not speed on small inputs. WIP: only fires when worker_sort_and_limit fires, i.e. single-table `ORDER BY LIMIT k`. UNION-of-tables (the prod query.sql shape) does not populate worker_sort_and_limit yet (separate ctx-propagation gap). --- .../distributed_partial_aggregate.rs | 52 +++++++++++++++++-- .../src/queryplanner/optimizations/mod.rs | 11 +++- .../src/queryplanner/query_executor.rs | 2 + 3 files changed, 60 insertions(+), 5 deletions(-) diff --git a/rust/cubestore/cubestore/src/queryplanner/optimizations/distributed_partial_aggregate.rs b/rust/cubestore/cubestore/src/queryplanner/optimizations/distributed_partial_aggregate.rs index 5246b1878f132..cde5f026e8e2f 100644 --- a/rust/cubestore/cubestore/src/queryplanner/optimizations/distributed_partial_aggregate.rs +++ b/rust/cubestore/cubestore/src/queryplanner/optimizations/distributed_partial_aggregate.rs @@ -1,5 +1,6 @@ use crate::cluster::WorkerPlanningParams; use crate::queryplanner::check_memory::CheckMemoryExec; +use crate::queryplanner::group_by_limit_aggregate::GroupByLimitAggregateExec; use crate::queryplanner::inline_aggregate::{InlineAggregateExec, InlineAggregateMode}; use crate::queryplanner::planning::WorkerExec; use crate::queryplanner::query_executor::ClusterSendExec; @@ -286,13 +287,15 @@ pub fn push_sorted_partial_aggregate_below_merge( /// key) would drop partial states of tied groups. pub fn push_worker_sort_and_limit( p: Arc, + group_by_limit_factor: usize, ) -> Result, DataFusionError> { // Worker side: wrap the partial aggregate with a per-partition bounded sort. if let Some(w) = p.as_any().downcast_ref::() { let Some((cols, fetch)) = w.worker_sort_and_limit.clone() else { return Ok(p); }; - let Some(new_input) = resort_worker_subtree(&w.input, &cols, fetch) else { + let Some(new_input) = resort_worker_subtree(&w.input, &cols, fetch, group_by_limit_factor) + else { return Ok(p); }; return Ok(Arc::new(WorkerExec::new( @@ -324,8 +327,12 @@ pub fn push_worker_sort_and_limit( let Some((cols, fetch)) = cs.worker_sort_and_limit.clone() else { return Ok(p); }; - let Some(new_worker_subtree) = resort_worker_subtree(&cs.input_for_optimizations, &cols, fetch) - else { + let Some(new_worker_subtree) = resort_worker_subtree( + &cs.input_for_optimizations, + &cols, + fetch, + group_by_limit_factor, + ) else { return Ok(p); }; let new_cs: Arc = @@ -377,6 +384,7 @@ fn resort_worker_subtree( worker_subtree: &Arc, cols: &[(usize, bool, bool)], fetch: usize, + group_by_limit_factor: usize, ) -> Option> { let partial = locate_partial_aggregate(worker_subtree)?; let schema = partial.schema(); @@ -392,8 +400,44 @@ fn resort_worker_subtree( }); } let worker_order = LexOrdering::new(exprs); + + // Trim during aggregation: replace the partial hash aggregate with a GroupByLimitAggregateExec + // so it keeps only the top-k groups by `cols` instead of materializing every group and letting + // the Sort below trim afterwards.

Adds planning coverage (bare LIMIT, UNION ALL + bare LIMIT) and a bare-LIMIT execution assertion to topk_hash_aggregate_trim; excludes that test from the migration harness (new test, no recorded fixture). --- .../cubestore-sql-tests/src/tests.rs | 49 +++++++++++++++++++ .../cubestore/src/queryplanner/planning.rs | 38 ++++++++++---- 2 files changed, 78 insertions(+), 9 deletions(-) diff --git a/rust/cubestore/cubestore-sql-tests/src/tests.rs b/rust/cubestore/cubestore-sql-tests/src/tests.rs index 551c70234c839..b2cd81474808d 100644 --- a/rust/cubestore/cubestore-sql-tests/src/tests.rs +++ b/rust/cubestore/cubestore-sql-tests/src/tests.rs @@ -427,6 +427,7 @@ lazy_static::lazy_static! { "limit_pushdown_group_nonprefix_order", "prefilter_chunks_shared_scan", "planning_topk_hash_aggregate", + "topk_hash_aggregate_trim", ].into_iter().map(ToOwned::to_owned).collect(); } @@ -3284,6 +3285,37 @@ async fn planning_topk_hash_aggregate(service: Box) -> Result<(), router_pp ); + // Bare LIMIT (no ORDER BY) on a non-indexed group column: the limit can't ride the index, so the + // worker still trims to the smallest groups by the full group key -- "any k" made deterministic. + let p = service + .plan_query("SELECT day, SUM(hits) FROM s.Data GROUP BY 1 LIMIT 10") + .await?; + let pp = pp_phys_plan_ext(p.worker.as_ref(), &PPOptions::none()); + assert!( + pp.contains("GroupByLimitAggregate, k: 10, factor: 2,") + && pp.contains("(0, SortOptions { descending: false, nulls_first: false })"), + "expected GroupByLimitAggregate on a bare LIMIT, got:\n{}", + pp + ); + + // UNION ALL + bare LIMIT: the per-branch trim descriptor must survive the cluster-send pull-up + // over the union so the worker still trims above the union. + service + .exec_query("CREATE TABLE s.Data2(url text, day int, hits int)") + .await?; + let p = service + .plan_query( + "SELECT day, SUM(hits) FROM \ + (SELECT * FROM s.Data UNION ALL SELECT * FROM s.Data2) u GROUP BY 1 LIMIT 10", + ) + .await?; + let pp = pp_phys_plan_ext(p.worker.as_ref(), &PPOptions::none()); + assert!( + pp.contains("GroupByLimitAggregate, k: 10, factor: 2,") && pp.contains("Union"), + "expected GroupByLimitAggregate over the Union, got:\n{}", + pp + ); + Ok(()) } @@ -3340,6 +3372,23 @@ async fn topk_hash_aggregate_trim(service: Box) -> Result<(), Cub ); } + // Bare LIMIT 3 (no ORDER BY): the trim orders by the full group key, so "any 3" resolves to the + // 3 smallest by (a, b).

emits the trimmed top-k unsorted). CoalescePartitions spawns a task per input partition, so the per-union-branch aggregates run in parallel -- the sorted merge drained them on a single task. - Router: SortExec(T, fetch=k) <- AggregateExec(Final, hash) <- CoalescePartitions <- ClusterSend. The explicit top-k sort by the full total order T is required even for a bare LIMIT: it keeps exactly the groups every worker kept (fully combined here), where a plain limit could take an undercounted group only one worker retained. On the production-dump UNION query (GROUP BY 6 cols, LIMIT 10): ~2.1x faster (~3.1s -> ~1.5s) at neutral peak RSS, because the worker now uses ~2 cores instead of 1. Same result as the sorted path (ORDER BY and bare LIMIT verified).

The hash-final path (worker CoalescePartitions -> router hash Final + Sort(T, fetch=k)) is strictly better: same memory, ~2x faster because CoalescePartitions parallelizes the per-partition aggregates. So remove the sorted variant and the CUBESTORE_GROUP_BY_LIMIT_HASH_FINAL flag entirely; hash-final is now how the trimmed top-k is always combined. Two knobs remain: - group_by_limit_factor (env CUBESTORE_GROUP_BY_LIMIT_FACTOR, >0): whether to use the trimming aggregate at all. 0 leaves the plan untouched (master behavior). - CUBESTORE_GROUP_BY_LIMIT_PER_PARTITION: whether to push it below the merge (per-partition N-way) -- still experimental, default off. push_worker_sort_and_limit now returns early when factor == 0.

The memory scan previously rejected this as an "index schema / chunk schema mismatch", so any query touching an uncompacted (in-memory) chunk failed under dictionary encoding. Cast the chunk batches up to the index schema instead (Utf8 -> Dictionary via cast_record_batch_to_schema): the memory scan now matches the dictionary parquet partitions and feeds the dict-aware aggregate, so streaming / freshly-imported data gets the same path and benefit. Tests: - test_cast_record_batch_to_dictionary_schema: the cast preserves values and nulls and leaves non-string columns untouched. - dictionary_encoding_in_memory_group_by: dictionary encoding on, a unique-key table (streaming in-memory chunks), no compaction, group-by the string column returns correct sums (asserts the chunks are in-memory). --- .../src/queryplanner/query_executor.rs | 113 ++++++++++++++++-- .../cubestore/src/store/compaction.rs | 80 +++++++++++++ 2 files changed, 182 insertions(+), 11 deletions(-) diff --git a/rust/cubestore/cubestore/src/queryplanner/query_executor.rs b/rust/cubestore/cubestore/src/queryplanner/query_executor.rs index 7cf87eb00807b..093b0a95fbaf2 100644 --- a/rust/cubestore/cubestore/src/queryplanner/query_executor.rs +++ b/rust/cubestore/cubestore/src/queryplanner/query_executor.rs @@ -970,18 +970,21 @@ impl CubeTable { "Record batch for in memory chunk {:?} is not provided", chunk )))?; - if let Some(batch) = record_batches.iter().next() { - if batch.schema() != index_schema { - return Err(CubeError::internal(format!( - "Index schema {:?} and in memory chunk schema {:?} mismatch", - index_schema, - record_batches[0].schema() - ))); - } - } + // In-memory chunks are written with plain column types.

So with dictionary encoding on, any top-k-by-aggregate query crashed the worker subprocess. Special-case ScalarValue::Dictionary at the function level (the macro is left untouched): build into a StringDictionaryBuilder and append the inner Utf8 value, so the top-k result columns keep the dictionary type the schema expects. Grouping already works (ScalarValue::Dictionary hashes/compares by its resolved inner value) and cmp_same_types only ever sees aggregate values, so no other change is needed. Covers the only dictionary layout CubeStore produces (Dictionary(Int32, Utf8)); other layouts still panic explicitly. Verified on the production dump: ORDER BY sum(...) DESC LIMIT 10 with dictionary encoding on now returns the same rows as with it off.

ORDER BY LIMIT n the worker shipped every group to the router (router-only bounding -> the inline-aggregate limit OOM class). Split resort_worker_subtree by partial aggregate kind, one mechanism two shapes: - inline/sorted: SortPreservingMerge(T) <- Sort(T, fetch, per partition) -- we can't trim a sorted aggregate and don't know the group count, so always bound with a sort. Router: sorted final over a sort-preserving merge (the query's Sort+Limit does the final bounding, no extra Sort). - hash: the trimming GroupByLimitAggregate + coalesce (factor-aware), router does the hash final + Sort(fetch). Unchanged. Also drop the top-level factor==0 early return so the inline bounding applies regardless of the trim factor (factor only gates the hash trim). Tests: un-ignore worker_sort_and_limit_cluster; update its hash-path case to assert the GroupByLimitAggregate trim instead of the old worker Sort.
