Fast time-series Postgres extension, written in Rust
pg_deltax is a Postgres extension for time-series and columnar storage, written in Rust on pgrx 0.17.
The Rust internals: type-specific codecs (Gorilla XOR, delta-of-delta, FOR+bitpacking, dictionary, LZ4), vectorized batch filters in tight loops bypassing Postgres's per-row ExecQual, parallel aggregation, and a shared-memory blob cache.
Early days, but ClickBench benchmarks (reproducible via `make benchmarks`) put it ahead of TimescaleDB.
