# This test verifies following for 'consistent_transactions'
# event name:
# - Verify that entries corresponding to the
# 'consistent_transactions' performance schema
# instrumented memory are in the memory table only during the
# execution of the group replication plugin.
# - Verify that the sum of bytes allocated is greater than zero for a
# transaction.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Verify that the entries corresponding to the
# instrumented memory are in the setup instruments
# table and the memory summary tables for the event
# consistent_transactions.
# 2. Verify that the sum of bytes allocated is greater than
# zero for a transaction.
# 3. Stop GR
# 4. Verify that the entries corresponding to the instrumented
# consistent_transactions remain in the tables after stopping GR.
# 5. Assert that the number of bytes allocated for consistent_transactions
# event must be 0.
# 6. Clean up.
