 A local Prometheus installation periodically compacts older data to improve query efficiency. Since the sidecar backs up data as soon as possible, we need a way to apply the same process to data in the object storage.
 
-The compactor component simple scans the object storage and processes compaction where required. At the same time it is responsible for creating downsampled copies of data to speed up queries.
