gwasvcf vs TimescaleDB: at a glance
What is gwasvcf?
gwasvcf has stopped adding features and now just keeps proxy matching from failing.
gwasvcf reads and queries GWAS summary statistics stored as VCF, with LD proxy lookup as its most-used entry point. Every release in the visible window is a fix, and all but one land in or around proxy_match(). The last functional addition was gwasvcf_to_summaryset() in 0.1.2, which hands data to gwasglue2 rather than doing new work here.
What is TimescaleDB?
TimescaleDB is paying down correctness debt in its columnstore query paths.
The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.

gwasvcf has stopped adding features and now just keeps proxy matching from failing.
◆ Current state
gwasvcf reads and queries GWAS summary statistics stored as VCF, with LD proxy lookup as its most-used entry point. Every release in the visible window is a fix, and all but one land in or around proxy_match(). The last functional addition was gwasvcf_to_summaryset() in 0.1.2, which hands data to gwasglue2 rather than doing new work here.
◆ Where it's heading
The package is in custodial maintenance inside the MRC IEU OpenGWAS stack, and its releases are reactive: each one answers a specific user-reported failure, credited to the reporter. The 0.1.6 pattern is telling — rather than replace the proxy VCF construction, it keeps the original path and adds a fallback only for inputs that fail, so existing results are left bit-for-bit unchanged.
◆ Prediction
Expect further narrow robustness fixes to proxy_match() driven by user-reported VCF shapes; nothing in the entries suggests new analysis capability is being built here rather than in gwasglue2.
TimescaleDB
5.0ANALYTICS
TimescaleDB is paying down correctness debt in its columnstore query paths.
◆ Current state
The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.
◆ Where it's heading
The feature work of 2.27 and 2.28 - vectorized filter evaluation, first/last derived straight from columnstore batch metadata, sparse indexes, SkipScan on compressed data - has been followed by a steady stream of fixes to those same code paths. 2.29.2 alone repairs SkipScan dropping uncompressed rows, sparse-index pushdown returning wrong results for IS NULL, and gapfill over window aggregates. That is the normal cost of pushing query optimizations into a compressed columnar store, and the project is working through it release by release rather than pausing.
◆ Prediction
With three consecutive patch releases on the 2.29 line and no new highlighted features since 2.29.0, the next minor is likely to resume the columnstore performance work - though the density of wrong-results fixes suggests more patches first.
