What is Apache Airflow?

Airflow 3.4 reaches its first release candidate, a week after the 10-20 provider wave.

Airflow published constraints for 3.4.0rc1 on Oct 28, which means core 3.4 has moved from beta to release candidate. The surrounding activity is the 2026-10-20 provider batch (Snowflake 6.20, SMTP 3.2, OpenSearch 1.15, OpenAI 2.2, Standard 1.21 and others), all published without release notes, plus a TypeScript SDK 1.0.0-beta1.

What is Buildkite?

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

Apache Airflow vs Buildkite: editorial side-by-side

A
Apache Airflow
INFRA · APIS
5.0

Airflow 3.4 reaches its first release candidate, a week after the 10-20 provider wave.

◆ Current state

Airflow published constraints for 3.4.0rc1 on Oct 28, which means core 3.4 has moved from beta to release candidate. The surrounding activity is the 2026-10-20 provider batch (Snowflake 6.20, SMTP 3.2, OpenSearch 1.15, OpenAI 2.2, Standard 1.21 and others), all published without release notes, plus a TypeScript SDK 1.0.0-beta1.

◆ Where it's heading

Core 3.4 is following the usual beta-to-RC path while providers ship on their own batch schedule. The TypeScript SDK beta and the common-ai provider suggest Airflow is widening who can author tasks, though the feed shows tags rather than feature notes.

◆ Prediction

Expect further 3.4.0 release candidates and then a 3.4.0 final within a few weeks; the entries don't show which features anchor it.

Buildkite

5.0

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

◆ Current state

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

◆ Where it's heading

The pattern is to centralize and codify: settings move from individual agents to clusters, and from the UI to Terraform and APIs, and capabilities such as caching move from plugins into the agent itself. Test Engine is turning into a programmable flaky-test management layer instead of a dashboard.

◆ Prediction

Expect more Test Engine monitors and actions that can be managed in code, and cache controls such as eviction and scoping, now that Cache is GA.
