This table shows the current general transaction execution
status on the replica. The table provides information about
general aspects of transaction applier status that are not
specific to any thread involved. Thread-specific status
information is available in the
if the replica is multithreaded).
table has these columns:
The replication channel which this row is displaying. There is always a default replication channel, and more replication channels can be added. See Section 17.2.2, “Replication Channels” for more information.
ONwhen the replication channel's applier threads are active or idle,
OFFmeans that the applier threads are not active.
If the replica is waiting for
DESIRED_DELAYseconds to pass since the source applied a transaction, this field contains the number of delay seconds remaining. At other times, this field is
DESIRED_DELAYvalue is stored in the
replication_applier_configurationtable.) See Section 17.4.11, “Delayed Replication” for more information.
Shows the number of retries that were made because the replication SQL thread failed to apply a transaction. The maximum number of retries for a given transaction is set by the
slave_transaction_retriessystem variable. The
replication_applier_status_by_workertable shows detailed information on transaction retries for a single-threaded or multithreaded replica.
