Apache Storm vs OpenObserve: at a glance
What is Apache Storm?
Storm 3.2 fixes three access-control CVEs and ends the 2.x line.
Apache Storm 3.2.0 arrived on 11 November with fixes for three CVEs: the supervisor page revealing other users' topologies, the Logviewer following symlinks past ACLs, and DRPC impersonation bypassing the authorizer. It declares Storm 2.x end of life, removes several deprecated configs and serializers, and adds pluggable tuple tracing with OpenTelemetry, a Prometheus reporter for V2 metrics and opt-in virtual threads on Java 25.
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.

2.5ANALYTICS
Storm 3.2 fixes three access-control CVEs and ends the 2.x line.
◆ Current state
Apache Storm 3.2.0 arrived on 11 November with fixes for three CVEs: the supervisor page revealing other users' topologies, the Logviewer following symlinks past ACLs, and DRPC impersonation bypassing the authorizer. It declares Storm 2.x end of life, removes several deprecated configs and serializers, and adds pluggable tuple tracing with OpenTelemetry, a Prometheus reporter for V2 metrics and opt-in virtual threads on Java 25.
◆ Where it's heading
The 3.x line keeps pairing security hardening with removal of legacy code, following 3.0's Clojure removal and 3.1's long hardening list. With 2.x now unsupported and deprecated APIs classified for removal, Storm is narrowing to a modern-JVM codebase with standard observability hooks.
◆ Prediction
Further removals flagged in 3.2, such as the Pacemaker subsystem, are likely in the next minor, alongside more security fixes from outside reporters.
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.
