This maintenance release addresses performance limitations during hard domain migrations for participants with a large Active Contract Set (ACS).
What’s New
Domain Migration Performance Improvement
The "reconnect" step of hard domain migration has been optimized to replay ACS changes into the ACSCommitmentProcessor much faster for Canton deployments using PostgreSQL databased backend. In order to enable the faster alternative database query, use this new configuration option:
Together with the new index on the active_contracts table, this significantly speeds up the initial domain reconnection following a hard domain migration. This change requires a database migration to be applied to the nodes when upgrading to this Canton version. Index creation is expected to take roughly a couple of seconds per 1 million records in the active_contracts table.
The previous behavior can be restored by setting the configuration option to false.
