What is Apache Druid?

Druid 38 drops Java 17, recommends Java 25 and took longer to arrive than its predecessors

Druid 38.0.0 shipped on October 1 with over 250 changes from 37 contributors. It adds Java 25 support, drops Java 17, and introduces Historical tier aliases and a realtimeSegmentsMode query context that replaces realtimeSegmentsOnly. MSQ workers now fetch input files in the background by default, and Druid 38 is the last major that reads legacy ZSTD frames.

What is Elasticsearch?

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

Druid 38 drops Java 17, recommends Java 25 and took longer to arrive than its predecessors

◆ Current state

Druid 38.0.0 shipped on October 1 with over 250 changes from 37 contributors. It adds Java 25 support, drops Java 17, and introduces Historical tier aliases and a realtimeSegmentsMode query context that replaces realtimeSegmentsOnly. MSQ workers now fetch input files in the background by default, and Druid 38 is the last major that reads legacy ZSTD frames.

◆ Where it's heading

The release is operator-focused: tier aliases and segment-mode controls target blue/green deployments and large clusters, and background fetching and Dart prefetching chase throughput. Compatibility remains a stated part of shipping, with explicit deprecations and upgrade notes. The gap from 37.0.0 was nearly five months, against about three for the release before, so the quarterly rhythm has loosened.

◆ Prediction

A 39 release candidate is the next visible step, and removal of legacy ZSTD frame support is already announced for a future release. Timing is less certain now that the last gap ran past a quarter.

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

◆ Current state

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

◆ Where it's heading

Serverless is where the feature work shows up: cross-project search and Azure Private Link both landed there in about a month. The self-managed lines are getting steady patch trains, which keeps 8.19 viable as a long-lived branch.

◆ Prediction

Expect further Serverless parity with self-managed cluster features, and continued patch trains across branches. The patch notes shown here do not support a more specific call.
