  title: Thanos Compact Alerts Stores API
  description: The Thanos Compact HTTP API provides operational endpoints for the Compactor component, which runs as a singleton process applying Prometheus compaction procedures to TSDB blocks stored in object storage. It performs downsampling at 5-minute and 1-hour resolutions and enforces retention policies to reduce long-term storage costs.
