26.12.11.4 The replication_applier_status Table
This table shows the current general transaction execution
status on the slave server. 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
replication_applier_status_by_coordinator
table (and
replication_applier_status_by_worker
if the slave is multithreaded).
The replication_applier_status
table has these columns:
CHANNEL_NAME
The replication channel which this row is displaying. There is always a default replication channel, and more replication channels can be added. See Section 17.2.3, “Replication Channels” for more information.
SERVICE_STATE
Shows
ON
when the replication channel's applier threads are active or idle,OFF
means that the applier threads are not active.REMAINING_DELAY
If the slave is waiting for
DESIRED_DELAY
seconds to pass since the master applied an transaction, this field contains the number of delay seconds remaining. At other times, this field isNULL
. (TheDESIRED_DELAY
value is stored in thereplication_applier_configuration
table.) See Section 17.3.12, “Delayed Replication” for more information.COUNT_TRANSACTIONS_RETRIES
Shows the number of retries that were made because the slave SQL thread failed to apply a transaction. The maximum number of retries for a given transaction is set by the
slave_transaction_retries
system variable. Thereplication_applier_status_by_worker
table shows detailed information on transaction retries for a single-threaded or multithreaded slave.
The replication_applier_status
table has these indexes:
Primary key on (
CHANNEL_NAME
)
TRUNCATE TABLE
is not permitted
for the
replication_applier_status
table.

columns and SHOW SLAVE STATUS
columns.
