Overview

Package gc contains the functions needed to run garbage collection.

The gc.PieceTracker implements the segments loop Observer interface allowing us to subscribe to the loop to get information for every segment in the metabase db.

The gc.PieceTracker handling functions are used by the gc.Service to periodically account for all existing pieces on storage nodes and create "retain requests" which contain a bloom filter of all pieces that possibly exist on a storage node.

The gc.Service will send that request to the storagenode after a full segments loop iteration, and the storage node will use that request to delete the "garbage" pieces that are not in the bloom filter.

See storj/docs/design/garbage-collection.md for more info.
