TimescaleDB vs Grafana Loki: at a glance
What is TimescaleDB?
TimescaleDB 2.32 turns on its new integer compressor and drops superuser needs.
TimescaleDB ships on a steady cadence where most releases are columnstore, SkipScan and continuous aggregate fixes. 2.31.0 vectorized UPDATE and DELETE on compressed data and previewed an Adaptive Integer Compressor. 2.32.0 turns that compressor on by default, speeds continuous aggregate refreshes, and arrives with a larger than usual batch of security fixes: background workers, the scheduler and telemetry now run as the database owner rather than as superuser.
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.

TimescaleDB
5.0ANALYTICS
TimescaleDB 2.32 turns on its new integer compressor and drops superuser needs.
◆ Current state
TimescaleDB ships on a steady cadence where most releases are columnstore, SkipScan and continuous aggregate fixes. 2.31.0 vectorized UPDATE and DELETE on compressed data and previewed an Adaptive Integer Compressor. 2.32.0 turns that compressor on by default, speeds continuous aggregate refreshes, and arrives with a larger than usual batch of security fixes: background workers, the scheduler and telemetry now run as the database owner rather than as superuser.
◆ Where it's heading
Feature releases keep cutting the cost of running large hypertables, while 2.32 adds a second thread: running safely without superuser rights. That matters most for managed and multi-tenant Postgres setups where superuser is not available.
◆ Prediction
Expect quick 2.32.x patches for the new compressor and the owner-based worker model, as happened after 2.30's planner change; the release already points users to 2.32.1 before upgrading Postgres.
Grafana Loki
6.3ANALYTICS
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.
