Tips for Compressing with Existing Geodatabase Replicas

In a versioned environment, all edits are stored in what we call delta tables, or Adds and Deletes tables, and these tables are assigned to a unique state ID. Edits are held in the delta tables to handle any conflicts in a multi-user enterprise geodatabase. A compress operation trims the delta tables of any unreferenced state ids, consolidating the states lineage down to one state. If a state is still being referenced, it will remain in the delta tables, resulting in a partial compress.

In a fully compressed geodatabase, there are no rows in the delta tables, and the state tree is trimmed back to one state, state_id=0. Although a full compress is ideal, it is not always necessary and in some cases may not even be practical. For example, if there are many multi-generation replicas in your geodatabase that are not unregistered before the compress, you will need to send changes for all of these replicas to achieve a full compress. If there are many Two-way replicas, and you intend to fully compress both the parent and the child geodatabases, this process of synchronization will need to be done separately from both geodatabases, even if there are no changes to be sent.
