+For controlling metadata size and storage costs, Iceberg provides snapshot lifecycle management procedures such as [`expire_snapshots`](spark-procedures.md#expire-snapshots) for removing unused snapshots and no longer necessary data files based on table snapshot retention properties.
 
 **For more sophisticated snapshot lifecycle management, Iceberg supports branches and tags which are named references to snapshots with their own independent lifecycles. This lifecycle is controlled by branch and tag level retention policies.** 
 Branches are independent lineages of snapshots and point to the head of the lineage. 
 Branches and tags have a maximum reference age property which control when the reference to the snapshot itself should be expired.
 Branches have retention properties which define the minimum number of snapshots to retain on a branch as well as the maximum age of individual snapshots to retain on the branch. 
 These properties are used when the expireSnapshots procedure is run.
