Real-time analytics database for sub-second queries

druid.apache.org ↗

Druid ships a large major roughly every quarter and lets the release notes do the talking.

◆Current state
The feed alternates release-candidate tags with the majors they become: 35.0.1 in December, 36.0.0 in February, 37.0.0 in May. The majors are big and diffuse — 37.0.0 counts over 255 changes from 29 contributors, 36.0.0 over 189 from 34 — and are summarised by contributor counts and pointers to upgrade notes rather than headline features. The one patch in the window fixed segment-drop file descriptors leaking until process exit, which is the kind of detail that tells you who runs this: operators with long-lived clusters.
◆Where it's heading
This is a mature Apache project on a predictable cadence, where each release aggregates hundreds of contributions instead of pursuing a theme. Every major carries explicit incompatible-changes and upgrade notes, so compatibility management is treated as a first-class part of shipping. Nothing in the feed points toward a directional shift; the signal is steadiness.
◆Prediction
On this cadence the next major and its release candidate are due within a quarter of 37.0.0, likely with a similar volume of changes. What those changes contain cannot be inferred — the entries deliberately defer detail to the linked notes.

    Druid 37.0.0

    Druid 37.0.0 lands with over 255 changes from 29 contributors, alongside upgrade notes and a list of incompatible changes. A substantial major by volume, but the entry itself is a pointer — the direction has to be read from the linked notes, not here.

    druid-37.0.0-rc1

    A Maven release-plugin tag for the 37.0.0 release candidate, three weeks ahead of the final. Build machinery that the feed surfaces as an entry.

    druid-36.0.0-rc1

    The release-candidate tag for 36.0.0, carrying only the plugin's copy message. Same packaging artifact as the other rc entries.

    Druid 35.0.1

    A patch release fixing historical server segment dropping — memory mappings were left in place, holding file descriptors of deleted files open until the process exited — plus a protobuf extension fix. Narrow, but the failure mode it removes is a real operational hazard on long-running clusters.

    druid-35.0.1-rc2

    The second release candidate tag for 35.0.1, with no content beyond the tag copy. Release plumbing appearing in the feed.
