DeltaX (δx) - Fast time-series extension for PostgreSQL
Summary
DeltaX is a PostgreSQL extension that provides compression and columnar storage for time-series data, enabling analytics workloads to run inside Postgres with reduced storage and improved performance. The README discusses benchmarks, per-column codecs, ingestion paths, partitioning, and the open source Apache 2.0 licensing, framing δx as an open alternative to TimescaleDB when keeping data in Postgres matters.
