Apache Druid vs OpenObserve: at a glance
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 OpenObserve?
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
Apache Druid vs OpenObserve: editorial side-by-side
Apache Druid
2.5ANALYTICSINFRA · APIS
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.
OpenObserve
5.0ANALYTICS
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
◆ Current state
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
◆ Where it's heading
The 1.2 cycle is wider than metrics: rc2's fixes reveal on-call scheduling, fleet management, RUM, synthetics and incident root-cause features heading into the release. Several fixes tighten tenant and permission boundaries, which suggests multi-tenant and enterprise deployments are a priority before 1.2 goes stable.
◆ Prediction
Expect one more release candidate or a 1.2.0 stable soon, followed by 1.2.x backport patches as the 1.1 line had.
