What is Apache Druid?

Druid tags 39.0.0 rc1 five weeks after 38, a faster turn than recent majors.

Druid 38.0.0 shipped on October 1 with Java 25 support, Java 17 dropped, Historical tier aliases and a realtimeSegmentsMode query context. On November 6 the project tagged druid-39.0.0-rc1, about five weeks later. The tag carries no release notes yet.

What is SigNoz?

SigNoz moves log bodies to queryable JSON storage, at a disk cost during migration.

SigNoz now renders AI traces as a conversation in its Thread view, reading OTel gen_ai attributes and SDK-specific formats. The latest release starts moving log bodies to native JSON storage (body_v2), so any field in a log body can be queried by path with less data scanned. During the transition each log body is written twice, so OSS users need extra disk. The v1 alert rule API is still removed on November 11.

Apache Druid vs SigNoz: editorial side-by-side

2.5

Druid tags 39.0.0 rc1 five weeks after 38, a faster turn than recent majors.

◆ Current state

Druid 38.0.0 shipped on October 1 with Java 25 support, Java 17 dropped, Historical tier aliases and a realtimeSegmentsMode query context. On November 6 the project tagged druid-39.0.0-rc1, about five weeks later. The tag carries no release notes yet.

◆ Where it's heading

Majors have arrived every three to five months with 190-255 changes each; a 39 candidate five weeks after 38 shortens that gap. What 39 contains is not visible until the final notes publish.

◆ Prediction

Expect the 39.0.0 final within one to three weeks, following the rc-to-final gap of earlier majors.

5.0

SigNoz moves log bodies to queryable JSON storage, at a disk cost during migration.

◆ Current state

SigNoz now renders AI traces as a conversation in its Thread view, reading OTel gen_ai attributes and SDK-specific formats. The latest release starts moving log bodies to native JSON storage (body_v2), so any field in a log body can be queried by path with less data scanned. During the transition each log body is written twice, so OSS users need extra disk. The v1 alert rule API is still removed on November 11.

◆ Where it's heading

Alongside the LLM-observability work, SigNoz is rebuilding core storage and APIs: alerting moved to v2alpha1 schemas and logs to structured JSON. The cost is a run of migration notices that OSS and API users must act on.

◆ Prediction

Expect the double-write phase to end in a later release that makes body_v2 the default, and the v1 rules removal to ship on schedule.
