RedisTimeSeries is a time-series database that provides compression to reduce memory usage by up to 98% and improve performance. The RedisTimeSeries 1.2 release includes compression algorithms based on a Facebook paper that provide stable ingestion times independent of the number of data points. It also includes a reviewed API with performance improvements and clearer functionality. Performance testing showed ingestion throughput improved by 2-3% and query performance increased from 15-70% with the new release compared to the previous version.
