What is Fluent Bit?

Fluent Bit 5.2 adds its own typed scripting language for log processing

Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.

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.

Fluent Bit 5.2 adds its own typed scripting language for log processing

◆ Current state

Fluent Bit 5.2.0 shipped on 9 November. Its main addition is Fluent Typed Scripting, a processor with reusable typed policy packs, JSON field decoding and editor definitions, alongside the experimental browser runtime, output throttling and YAML config generated from CLI flags. The release also carries dozens of input hardening fixes, from OTLP decoding limits to syslog overflow and an AWS credential URI bypass. Experimental browser SDK builds from master keep appearing several times a day, each marked as unsupported for production.

◆ Where it's heading

After a month of hardening on 5.1, the 5.2 line puts new surface on top: a typed transform language that also runs in the browser build. Fluent Bit is moving from a collector configured with Lua snippets toward an agent with its own checked policy format.

◆ Prediction

Expect 5.2.x patch releases soon fixing regressions in the new FTS processor, and more FTS policy packs; the browser SDK is likely to stay labelled experimental for now.

5.0

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.
