What is Cortex?

Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.

Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.

What is OpenMetadata?

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

Cortex vs OpenMetadata: editorial side-by-side

2.5

Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.

◆ Current state

Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.

◆ Where it's heading

The storage arc toward Parquet continues: after 1.21 made Parquet a Store Gateway query mode, 1.22 shards files that exceed column limits. A second arc is protecting shared clusters from heavy tenants, through query eviction, resource-based throttling and concurrent data-byte limits on store gateways. The cleanup is the maturity arc from 1.21 carried further: no-op flags that were tolerated for releases now fail at startup.

◆ Prediction

1.22.0 final should follow rc.3, which added only two fixes. Operators should expect upgrade failures from leftover deprecated flags, and the release notes tell them to grep runtime configs before upgrading.

5.0

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

◆ Current state

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

◆ Where it's heading

The 2.0 launch is being paid for in connector repairs, and the cadence of roughly weekly maintenance suggests a large installed surface. Protecting user-managed metadata from bot ingestion, and multi-pod fixes in 2.0.6, point at production deployments rather than trials. The 2.1 candidate is the first sign of attention moving forward, but the published notes do not show its contents.

◆ Prediction

Expect a 2.1 release soon, with its real scope clearer once proper notes appear. 2.0.x maintenance should continue alongside it.
