Apache Druid vs Dagger: at a glance
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 Dagger?
Dagger now runs the engines for you and reports CI per test, not per job.
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.

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.
Dagger
2.5INFRA · APIS
Dagger now runs the engines for you and reports CI per test, not per job.
◆ Current state
Dagger's recent changelog holds two product moves. Cloud Engines, in September, are hosted engines with scale-out, distributed cache and observability, billed only for resources used, with Dagger claiming repeat work costs 5× less. Test-native CI, in October, tracks individual tests, so a failure names the test and only that test is run again. Around them sit cache and plumbing changes, including COPY steps that depend only on the files they copy and SSH-mounted remote filesystems.
◆ Where it's heading
Both moves rest on the same idea: treat the pipeline as a graph Dagger can see into, then avoid repeating work. A layer cache that survives unrelated file changes, per-test reruns and a distributed cache all reduce what a run must redo. Cloud Engines turn that saving into something sold, the one metered offering in these entries.
◆ Prediction
Expect Test-native CI and Cloud Engines to converge, with per-test reruns offered through hosted engines. That link is inferred from the two launches; the entries neither state it nor give pricing detail.
