Class ReviewDbBatchUpdate

java.lang.Object

com.google.gerrit.server.update.BatchUpdate

com.google.gerrit.server.update.ReviewDbBatchUpdate

All Implemented Interfaces:

java.lang.AutoCloseable

public class ReviewDbBatchUpdate
extends BatchUpdate

BatchUpdate implementation that supports mixed ReviewDb/NoteDb operations, depending on the migration state specified in NotesMigration.

When performing change updates in a mixed ReviewDb/NoteDb environment with ReviewDb primary, the order of operations is very subtle:

1. Stage NoteDb updates to get the new NoteDb state, but do not write to the repo.
2. Write the new state in the Change entity, and commit this to ReviewDb.
3. Update NoteDb, ignoring any write failures.

The implementation in this class is well-tested, and it is strongly recommended that you not attempt to reimplement this logic. Use BatchUpdate if at all possible.
