Compressing time-series data requires a fundamentally different approach than the general-purpose algorithms used in OLTP databases. In TimescaleDB this is handled by the hypercore engine — a hybrid row-columnar engine that uses specialized algorithms: delta encoding, delta-of-delta, Gorilla XOR and run-length encoding. This article explains how it works and how to configure compression so that you actually achieve that ratio.TimescaleDB compression - how it differs from PostgreSQL TOASTPostgreSQL has a built-in mechanism called…
