Release Notes

timescale/timescaledb (timescale/timescaledb)

`v2.25.0`

Compare Source

This release contains performance improvements and bug fixes since the 2.24.0 release. We recommend that you upgrade at the next available opportunity.

Highlighted features in TimescaleDB v2.25.0
This release features multiple improvements for continuous aggregates on the columnstore:

Faster refreshes: You can now utilize direct compress during materialized view refreshes, resulting in higher throughput and reduced I/O usage.
Efficiency: The enablement of delete optimizations significantly lowers system resource requirements.
Smaller transactions: Adjusted defaults for buckets_per_batch to 10 reduces transaction sizes, requiring less WAL holding time.
Faster queries: Smarter defaults for segmentby and orderby yield improved query performance and better compression ratio on the columnstore.

Sunsetting announcements

This release removes the WAL-based invalidation of continuous aggregates. This feature was introduced in 2.22.0 as tech preview to use logical decoding for building the invalidation logs. The feature was designed for high ingest workloads, reducing the write amplification. With the upcoming stream of improvements to continuous aggregates, this feature was deprioritized and removed.
The old continuous aggregate format, deprecated in version 2.10.0, has been fully removed from TimescaleDB in this release. Users still on the old format should read the migration documentation to migrate to the new format. Users of Tiger Cloud have already been automatically migrated.

`v2.24.0`

Compare Source

This release contains performance improvements and bug fixes since the 2.23.1 release. We recommend that you upgrade at the next available opportunity.

Highlighted features in TimescaleDB v2.24.0

Direct Compress just got smarter and faster: it now works seamlessly with hypertables generating continuous aggregates. Invalidation ranges are computed directly in-memory based on the ingested batches and written efficiently at transaction commit. This change reduces the IO footprint drastically by removing the write amplification of the invalidation logs.
Continuous aggregates now speak UUIDv7: hypertables partitioned by UUIDv7 are fully supported through an enhanced time_bucket that accepts UUIDv7 values and returns precise, timezone-aware timestamps — unlocking powerful time-series analytics on modern UUID-driven table schemas.
Lightning-fast recompression: the new recompress := true option on the convert_to_columnstore API enables pure in-memory recompression, delivering a 4–5× speed boost over the previous disk-based process.

ARM support for bloom filters
The sparse bloom filter indexes will stop working after upgrade to 2.24. If you are affected by this problem, the warning "bloom filter sparse indexes require action to re-enable" will appear in the Postgres log during upgrade.

In versions before 2.24, the hashing scheme of the bloom filter sparse indexes used to depend on the build options of the TimescaleDB executables. These options are set by the package publishers and might differ between different package sources or even versions. After upgrading to a version with different options, the queries that use the bloom filter lookups could erroneously stop returning the rows that should in fact match the query conditions. The 2.24 release fixes this by using distinct column names for each hashing scheme.

The bloom filter sparse indexes will be disabled on the compressed chunks created before upgrading to 2.24. To re-enable them, you have to decompress and then compress the affected chunks.

If you were running the official APT package on AMD64 architecture, the hashing scheme did not change, and it is safe to use the existing bloom filter sparse indexes. To enable this, set the GUC timescaledb.read_legacy_bloom1_v1 = on in the server configuration.

The chunks compressed after upgrade to 2.24 will use the new index format, and the bloom filter sparse indexes will continue working as usual for these chunks without any intervention.

For more details, refer to the pull request #8761.

Deprecations

The next release of TimescaleDB will remove the deprecated partial continuous aggregates format. The new format was introduced in 2.7.0 and provides significant improvements in terms of performance and storage efficiency. Please use cagg_migrate(<CONTINUOUS_AGGREGATE_NAME>) to migrate to the new format. Tiger Cloud users are migrated automatically.
In future releases the deprecated view timescaledb_information.compression_settings will be removed. Please use timescaledb_information.hypertable_columnstore_settings as a replacement.
The experimental view timescaledb_experimental.policies and the adjacent experimental functions add_policies, alter_policies, show_policies, remove_policies, and remove_all_policies to manage continuous aggregates will be removed in an upcoming release. For replacements, please use the Jobs API.

Backward-Incompatible Changes

#8761 Fix matching rows in queries using the bloom filter sparse indexes potentially not returned after extension upgrade. The version of the bloom filter sparse indexes is changed. The existing indexes will stop working and will require action to re-enable. See the section above for details.

This release contains performance improvements and bug fixes since the 2.22.1 release. We recommend that you upgrade at the next available opportunity.

Highlighted features in TimescaleDB v2.23.0

This release introduces full PostgreSQL 18 support for all existing features. TimescaleDB v2.23 is available for PostgreSQL 15, 16, 17, and 18.
UUIDv7 compression is now enabled by default on the columnstore. This feature was shipped in v2.22.0. It saves you at least 30% of storage and delivers ~2× faster query performance with UUIDv7 columns in the filter conditions.
Added the ability to set hypertables to unlogged, addressing an open community request #836. This allows the tradeoff between durability and performance, with the latter being favourable for larger imports.
By allowing set-returning functions in continuous aggregates, this releases addresses a long standing blocker, raised by the community #1717.

--- Find the job ID's of the concurrent refresh policies
SELECT * FROM timescaledb_information.jobs WHERE proc_name = 'policy_refresh_continuous_aggregate';
--- Remove the job
