What is Apache DolphinScheduler?

A slow, deliberate release train that keeps widening its cloud-task surface

DolphinScheduler ships on a multi-month cadence, with 3.4.2 (June 2026) and 3.4.1 (March 2026) as the recent stable points. The work is split between DSIP design proposals, new task plugins, and operator-facing hardening. Nothing in the window suggests a rewrite; this is a mature orchestrator accreting integrations.

What is samplr?

A cognitive-science sampling package ships once, then goes quiet for eighteen months

samplr compares human performance against sampling algorithms, giving cognitive scientists the MCMC machinery to test whether people behave like samplers. Its entire public history is three releases: a 1.0.0 in August 2024, a floating-point fix eighteen seconds later, and then nothing until a February 2026 patch. The release notes are unusually thin even by CRAN standards.

Apache DolphinScheduler vs samplr: editorial side-by-side

A0.0

A slow, deliberate release train that keeps widening its cloud-task surface

◆ Current state

DolphinScheduler ships on a multi-month cadence, with 3.4.2 (June 2026) and 3.4.1 (March 2026) as the recent stable points. The work is split between DSIP design proposals, new task plugins, and operator-facing hardening. Nothing in the window suggests a rewrite; this is a mature orchestrator accreting integrations.

◆ Where it's heading

The consistent direction is coverage of managed cloud compute — Amazon EMR Serverless joins the task-plugin catalog, following the earlier consolidation of Zeppelin, SageMaker and Kubernetes connections into a shared connection center. Alongside that, the project keeps tightening what operators can see and control at runtime: monitor-page visibility into running tasks per master/worker, configurable maximum runtime, and dispatch timeout handling for missing worker groups.

◆ Prediction

Expect the next release to add another managed-compute task plugin and continue routing its credentials through the connection center, since that is the pattern every recent integration has followed.

A cognitive-science sampling package ships once, then goes quiet for eighteen months

◆ Current state

samplr compares human performance against sampling algorithms, giving cognitive scientists the MCMC machinery to test whether people behave like samplers. Its entire public history is three releases: a 1.0.0 in August 2024, a floating-point fix eighteen seconds later, and then nothing until a February 2026 patch. The release notes are unusually thin even by CRAN standards.

◆ Where it's heading

The feed shows a package that shipped and stopped. The 2024 tags were both created in one sitting and say almost nothing; the 2026 release is a row-count bug in Mean_Variance() bundled with citation metadata, a dropped dependency and http-to-https link fixes — the housekeeping profile of a package being kept alive for the paper that cites it rather than actively developed.

◆ Prediction

Adding citation information to the README is usually the move of a maintainer expecting the package to be referenced rather than extended. On this cadence the next release is more likely another CRAN-hygiene patch than new algorithms; there is not enough in these notes to say otherwise.
