7.5.6 Replication Applier Metrics Component

The Replication Applier Metrics component implements two Performance Schema tables, listed here:

• replication_applier_metrics: Shows statistics for the replication applier, for a given replication channel.

• replication_applier_progress_by_worker: Shows statistics for the replication applier, for the worker with the given ID.

• Purpose: Implement replication applier statistics tables in the MySQL Performance Schema.

• URN: file://component_replication_applier_metrics

For installation instructions, see Section 7.5.1, “Installing and Uninstalling Components”.

This component was added in MySQL 9.1.0, and is available only as part of MySQL Enterprise Edition.

Important

The replication_applier_metrics component does not function when replica_parallel_workers=0.
