What is Strimzi?

Post-1.0 Strimzi tracks Kafka releases and hardens its own defaults

Strimzi is past its 1.0 break and into a steady minor-release rhythm, shipping roughly every two months. Each release tracks the newest Apache Kafka versions, retires the oldest, and widens the configuration surface — Gateway API listeners and per-broker templates in 1.1.0, per-pod additional volumes and Maven mirrors in 1.2.0. The v1-only CRD warning still heads every release body, so the 1.0 migration remains the gate on the installed base.

What is Windmill?

Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.

In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.

Post-1.0 Strimzi tracks Kafka releases and hardens its own defaults

◆ Current state

Strimzi is past its 1.0 break and into a steady minor-release rhythm, shipping roughly every two months. Each release tracks the newest Apache Kafka versions, retires the oldest, and widens the configuration surface — Gateway API listeners and per-broker templates in 1.1.0, per-pod additional volumes and Maven mirrors in 1.2.0. The v1-only CRD warning still heads every release body, so the 1.0 migration remains the gate on the installed base.

◆ Where it's heading

The operator is spending its post-1.0 cycles on how it manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has moved alpha to GA and is now permanently enabled, and 1.2.0 changes install-time defaults — Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens instead of auto-mounted ones. Feature gates continue to be the delivery mechanism: UseConnectBuildWithBuildah went beta in 1.0.0, UseBackgroundPodDeletion entered alpha in 1.1.0. Note that this feed publishes only release candidates; the finals never appear, so the RC is the record.

◆ Prediction

Expect UseBackgroundPodDeletion to move to beta and a ServerSideApply phase 2 gate to appear in the next minor, following the same alpha-beta-GA path the earlier gates took. Kafka 4.4 support is the likely headline whenever upstream ships it.

Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.

◆ Current state

In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.

◆ Where it's heading

The community edition is being loaded up with exactly what a data team needs to run a real trial: warehouse connectors, an unmodified dbt project, storage quota instead of an upload cap. Enterprise is being repositioned around scale and governance rather than feature access. The AI sessions track is developing on its own clock, moving from chat toward durable, versioned work products that survive a session.

◆ Prediction

Expect AI session artifacts to gain server-side persistence and sharing, since they are still stored in the browser and tied to the session. On the data side, the dbt runtime is likely to grow scheduling and lineage integration with the pipelines alpha rather than staying a standalone script language.
