What is TimescaleDB?

Every release in this window is columnstore work — compression is where TimescaleDB is spending

TimescaleDB is on a roughly two-week cadence and the releases are dominated by one subsystem. 2.28.0 made first() and last() far cheaper on compressed data by deriving the aggregates straight from columnstore batch metadata rather than decompressing. 2.29.0 added chunk exclusion for DML, so UPDATE and DELETE on hypertables take row exclusive locks only on the chunks actually being modified. The patch releases in between are almost entirely columnar correctness: wrong results from functions returning NULL in the columnar execution pipeline, sort transformation errors on negative constants, column ordering on first/last sparse indexes, incompatible smallint bloom filters, and crashes grouping by columns absent from the SELECT list under vectorized aggregation.

What is Lightdash?

Lightdash is making the whole instance — dashboards, roles, agents — checkable into git

Lightdash ships close to daily and the recent run splits cleanly in two. One track is the data-app platform: apps that call third-party HTTP APIs through a server-side proxy that never exposes a secret, a query inspector that links a chart back to the query behind it, and prompt-generated chart types. The other is making the instance declarative — content as code now covers charts, dashboards, spaces, permissions, virtual views, AI agents, automations, and organization-level users, groups and custom roles.

Every release in this window is columnstore work — compression is where TimescaleDB is spending

◆ Current state

TimescaleDB is on a roughly two-week cadence and the releases are dominated by one subsystem. 2.28.0 made first() and last() far cheaper on compressed data by deriving the aggregates straight from columnstore batch metadata rather than decompressing. 2.29.0 added chunk exclusion for DML, so UPDATE and DELETE on hypertables take row exclusive locks only on the chunks actually being modified. The patch releases in between are almost entirely columnar correctness: wrong results from functions returning NULL in the columnar execution pipeline, sort transformation errors on negative constants, column ordering on first/last sparse indexes, incompatible smallint bloom filters, and crashes grouping by columns absent from the SELECT list under vectorized aggregation.

◆ Where it's heading

The compression layer is no longer a storage option bolted onto hypertables — it is being turned into a full query path, with its own aggregate pushdowns, sparse indexes, bloom filters and vectorized execution. The bug pattern confirms how new that path still is: several patches fix wrong results rather than crashes, which is what a young execution engine produces as it meets real query shapes. The DML chunk-exclusion work in 2.29.0 shows the other half of the effort, reducing the lock footprint of writes so compressed hypertables stay usable under mutation, not just under read.

◆ Prediction

Given that every release in this window touches the columnstore and several fix correctness rather than performance, the next releases should continue hardening that path — more vectorized-aggregation and sparse-index fixes alongside further pushdowns. The entries give no signal of work outside compression.

◆ Current state

Lightdash ships close to daily and the recent run splits cleanly in two.

◆ Where it's heading

Both tracks serve the same reader: a data team that wants BI it can build on and review in a pull request. Merging verified content with AI agents was the tell — humans and agents now draw on one trust layer, and the Lightdash MCP exposes it to outside tools like Claude and Cursor. The surface Lightdash is claiming is the semantic and governance layer, with the visualization layer increasingly something you describe rather than configure.

◆ Prediction

The export side is now complete enough that CI checks on Lightdash content — diffing or validating the exported definitions in a pull request — are the natural next step.
