# Check that Group Replication parallel applier parallelization
# indexes are corrected according to WL#8440.
#
# Steps:
# 1.  Setup a new group with four members.
#     Execute some transactions on member 1, 2 and 3 that will
#     be applied on member 4 through Group Replication applier.
#     Dump Group Replication applier channel relay log and
#     validate its indexes on member 4.
# 2.  Stop and start member 2 to force a relay log flush.
#     Start member 1 again and execute another transactions
#     on members 1 and 2.
#     Purpose of the test: show that local transactions do
#     not interfere with remote transactions, the ones that
#     go through parallel applier.
#     Dump Group Replication applier channel relay log and
#     validate its indexes on members 2 and 1.
# 3.  Wait for stable set propagation and certification info
#     garbage collection.
#     Execute some more transactions and assert that
#     last_committed index was update with previous
#     sequence_number, even when transactions do not
#     depend on previous transactions.
#     Dump Group Replication applier channel relay log and
#     validate its indexes on members 2 and 1.
# 4.  Test cleanup.
