public void updateMetadata(java.lang.String eventId,
                           TableAndStatistics sourceTable,
                           java.lang.String replicaDatabaseName,
                           java.lang.String replicaTableName,
                           ReplicaLocationManager locationManager)

updateMetadata

public void updateMetadata(java.lang.String eventId,
                           TableAndStatistics sourceTableAndStatistics,
                           PartitionsAndStatistics sourcePartitionsAndStatistics,
                           java.lang.String replicaDatabaseName,
