#
# ==== Purpose ====
#
# This test asserts that the information regarding the replication timestamps
# is displayed correctly when the system is running with MTS enabled.
#
# ==== 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 processed by the
# MTS coordinator (table: performance_schema.replication_connection_status)
# 2) The MTS coordinator puts the transaction into a worker's queue
# (table: performance_schema.replication_applier_status_by_coordinator)
# 3) A worker 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.
