Highlight vs TimescaleDB: at a glance
What is Highlight?
Highlight grew from session replay into SQL-driven observability, then went quiet in August 2025.
Highlight is an open-source observability stack covering session replay, errors, logs, traces and metrics. Its last tagged self-hosted release, docker-v0.5.6, shipped in August 2025 with session-replay performance fixes and session restarts. Nothing has been tagged since.
What is TimescaleDB?
TimescaleDB 2.31 speeds columnstore UPDATE/DELETE and previews a new integer compressor.
TimescaleDB ships on a steady biweekly cadence where most releases are bug-fix patches for the columnstore, SkipScan and continuous aggregates. Feature releases have chipped at the cost of big hypertables: 2.30.0 made last-point LIMIT queries independent of chunk count, and 2.31.0 vectorizes UPDATE and DELETE on compressed data, adds non-blocking move_to_columnstore(), and previews an Adaptive Integer Compressor claiming up to 20% better integer compression. The 2.30.x patches fixed duplicate rows and crashes from the previous release's new planner node.
Highlight vs TimescaleDB: editorial side-by-side
Highlight
0.0ANALYTICS
Highlight grew from session replay into SQL-driven observability, then went quiet in August 2025.
◆ Current state
Highlight is an open-source observability stack covering session replay, errors, logs, traces and metrics. Its last tagged self-hosted release, docker-v0.5.6, shipped in August 2025 with session-replay performance fixes and session restarts. Nothing has been tagged since.
◆ Where it's heading
Through 2025 the releases added OpenTelemetry metrics ingest, a SQL editor and builder for graphs, SQL alerts and dashboards created from log and trace views. That pushed Highlight from a replay tool toward a general telemetry platform. The cadence then slowed from roughly monthly to a two-month gap before stopping.
◆ Prediction
The entries show no release in more than a year, so the self-hosted line's future is unclear. Any new tag would most likely be maintenance on session replay and OTel ingestion.
TimescaleDB
5.0ANALYTICS
TimescaleDB 2.31 speeds columnstore UPDATE/DELETE and previews a new integer compressor.
◆ Current state
TimescaleDB ships on a steady biweekly cadence where most releases are bug-fix patches for the columnstore, SkipScan and continuous aggregates. Feature releases have chipped at the cost of big hypertables: 2.30.0 made last-point LIMIT queries independent of chunk count, and 2.31.0 vectorizes UPDATE and DELETE on compressed data, adds non-blocking move_to_columnstore(), and previews an Adaptive Integer Compressor claiming up to 20% better integer compression. The 2.30.x patches fixed duplicate rows and crashes from the previous release's new planner node.
◆ Where it's heading
The columnstore is being made a place where data can be changed, not just queried: chunk-level locking for DML in 2.29, vectorized DML and non-blocking compression in 2.31. Granular continuous-aggregate refresh is maturing alongside with APIs, views and refresh statistics. Each minor release is still followed by correctness patches.
◆ Prediction
2.32.0 will enable the Adaptive Integer Compressor by default, as the 2.31 notes state. Expect a couple of 2.31.x patches for the new DML and compression paths first.
