What is Cortex?

Cortex is betting on Parquet block storage and graduating years of experimental features.

Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.

What is dbt Core?

dbt's 1.x releases now point users at v2 straight from the command line.

dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 2.0 dev channel has since added read-only Databricks Unity Catalog access through Lake Compute. The 1.x line is still shipping: 1.13.0b1 adds an opt-in --use-v2-parser that hands parsing to the Fusion parser, and today's 1.12.6 prints a v2 availability notice on dbt --version and relays Fusion parser logs through the otel log format.

Cortex is betting on Parquet block storage and graduating years of experimental features.

◆ Current state

Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.

◆ Where it's heading

Two arcs run in parallel. The storage arc is moving Cortex off pure TSDB blocks toward Parquet, first as a converter and format, then as a queryable Store Gateway mode — the same columnar direction the rest of the observability market has taken for long-retention data. The maturity arc is a deliberate clearing of the experimental backlog, with six subsystems graduating in one release and their flags renamed to drop the experimental prefix. Layered on both is a distinct hardening push: the latest candidate bounds gossip connections, caps decompressed request bodies, adds HMAC stream authentication and validates tenant IDs against the authenticated caller.

◆ Prediction

Expect Parquet to keep progressing from experimental toward default, following the path the bucket index just completed. The security work in 1.21.1 reads like a systematic pass over untrusted input paths rather than a response to a single report, so more of the same in the ingestion and gossip layers is likely.

6.3

dbt's 1.x releases now point users at v2 straight from the command line.

◆ Current state

dbt 2.0 GA split the project into a proprietary 'dbt' binary and dbt-oss, and the 2.0 dev channel has since added read-only Databricks Unity Catalog access through Lake Compute. The 1.x line is still shipping: 1.13.0b1 adds an opt-in --use-v2-parser that hands parsing to the Fusion parser, and today's 1.12.6 prints a v2 availability notice on dbt --version and relays Fusion parser logs through the otel log format.

◆ Where it's heading

The 1.x branch is being turned into an on-ramp for v2: a PyPI banner in 1.12.5, a CLI notice in 1.12.6, deprecated-version warnings and the Fusion parser opt-in in 1.13. Meanwhile 2.0 work concentrates on adapter parity (ClickHouse, Databricks) and Lake Compute.

◆ Prediction

Expect 1.13 to reach GA with the v2 parser opt-in and more migration prompts, and 2.0.x to extend Lake Compute past read-only Unity access. The entries don't show an end-of-life date for 1.x.
