Grafana Loki vs Apache Storm: at a glance
What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
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.

Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
Apache Storm
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.
