# Test circular replication where galera cluster is async replica and master

# ---async replication-->replica1 #1 <--galera replication--> node_2 #2
# ^ ^

#
# Test outline:
#
# - Create user for async replication in primary1
# - Create user for async replication in primary2
# - Create table and some data in primary1
# - Verify that table and data is replicated to galera nodes
# - Verify that mysql.gtid_slave_pos has some rows in all Galera nodes
# - Verify that gtid_slave_pos, gtid_binlog_pos and gtid_current_pos are
# same in all Galera nodes and primary1
# - Verify that writes on Galera nodes are replicated to all nodes
# and to primary1
#
# The galera/galera_3nodes_as_slave.cnf describes the setup of the nodes
