TIMESCALEDB COMPRESSION: HYPERCORE AND COLUMNAR STORAGE WITH UP TO 98% RATIO IN POSTGRESQL

Summary from the TLDR Dev newsletter

TimescaleDB uses a hybrid row-columnar engine called Hypercore to achieve up to 98% compression for time-series data within PostgreSQL. This technology uses specialized algorithms like delta encoding, Gorilla XOR, and run-length encoding to optimize cross-row patterns that general-purpose databases often ignore. Data must be properly organized using specific parameters that group similar information into compressed batches of approximately 1,000 rows.
