OpenMetadata vs TimescaleDB: at a glance
What is OpenMetadata?
A second 2.0 release candidate lands while 1.13 keeps absorbing governance and CVE fixes.
OpenMetadata is running two lines at once. The 2.0.0 major is on its second release candidate, both explicitly marked dev and test only with no stated changes. The 1.13 line continues as the shipping product: 1.13.3 fixed Snowflake foreign-key collisions across tables sharing a constraint name, unstuck data contracts left at Running, and repaired poisoned governance trigger filters, while 1.12.14 and 1.13.2 were dominated by dependency CVE patching across MLflow, PyArrow, log4j and the ingestion images.
What is TimescaleDB?
TimescaleDB is paying down correctness debt in its columnstore query paths.
The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.

OpenMetadata
5.0ANALYTICS
A second 2.0 release candidate lands while 1.13 keeps absorbing governance and CVE fixes.
◆ Current state
OpenMetadata is running two lines at once. The 2.0.0 major is on its second release candidate, both explicitly marked dev and test only with no stated changes. The 1.13 line continues as the shipping product: 1.13.3 fixed Snowflake foreign-key collisions across tables sharing a constraint name, unstuck data contracts left at Running, and repaired poisoned governance trigger filters, while 1.12.14 and 1.13.2 were dominated by dependency CVE patching across MLflow, PyArrow, log4j and the ingestion images.
◆ Where it's heading
The direction was set by 1.13.0, which made MCP a first-class service category and added an RDF knowledge graph; everything since has been consolidation around those two surfaces plus a heavy security-patch cadence. With 2.0 now on its second RC and carrying no published notes, the interesting question — what actually changes in the major — remains unanswered by the entries themselves.
◆ Prediction
Expect further 2.0 release candidates before a final, and continued 1.13.x maintenance releases weighted toward governance-workflow fixes and dependency patching until the major stabilizes.
TimescaleDB
5.0ANALYTICS
TimescaleDB is paying down correctness debt in its columnstore query paths.
◆ Current state
The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.
◆ Where it's heading
The feature work of 2.27 and 2.28 - vectorized filter evaluation, first/last derived straight from columnstore batch metadata, sparse indexes, SkipScan on compressed data - has been followed by a steady stream of fixes to those same code paths. 2.29.2 alone repairs SkipScan dropping uncompressed rows, sparse-index pushdown returning wrong results for IS NULL, and gapfill over window aggregates. That is the normal cost of pushing query optimizations into a compressed columnar store, and the project is working through it release by release rather than pausing.
◆ Prediction
With three consecutive patch releases on the 2.29 line and no new highlighted features since 2.29.0, the next minor is likely to resume the columnstore performance work - though the density of wrong-results fixes suggests more patches first.
