# ==== Purpose ====
|
|
#
|
|
# This test asserts that the information regarding the replication timestamps
|
|
# is displayed correctly when the system is running with MTS disabled.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# Five transaction types are tested:
|
|
# - create table
|
|
# - insert
|
|
# - update
|
|
# - delete
|
|
# - drop table
|
|
# For each statement, the test asserts that the information concerning the
|
|
# transaction that is currently being processed matches what is expected
|
|
# before and after each of the following replication stages is completed for
|
|
# that transaction:
|
|
# 1) The connection thread queues the transaction to be applied by the applier
|
|
# thread (table: performance_schema.replication_connection_status)
|
|
# 2) The applier thread applies the transaction
|
|
# (table: performance_schema.replication_applier_status_by_worker)
|
|
#
|
|
# The second part of the test checks if the table
|
|
# performance_schema.replication_applier_status_by_worker displays the correct
|
|
# information when the slave cannot apply a transaction due to an error.
|
|
# Two types of transactions are tested: DDL (DROP table) and DML (insert). After
|
|
# the slave fails applying each transaction, the test verifies that
|
|
# last_applied_transaction still shows the last transaction applied before the
|
|
# failed one, and also that applying_transaction was cleared.
|
|
# Also check that when an STS slave is restarted with MTS enabled, the table
|
|
# performance_schema.replication_applier_status_by_coordinator shows the
|
|
# appropriate information.
