#
# Test Galera as a replica to a MariaDB async replication
#
# MariaDB
# primary ---async replication--->galera node_2 (replica)<----galera replication---> galera node1
#
# Test outline:
#
# - Create user for async replication
# - Create table and some data in primary
# - 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
# - Verify that we can shutdown and restart Galera replica (node #2)
# - Verify that gtid_slave_pos, gtid_binlog_pos and gtid_current_pos are
# same in all Galera nodes
# - Verify that mysql.gtid_slave_pos table has limited amount of rows
# - Veruft that ddl works (drop table)
#
# Similar test is done so that new rows are added to table in
# primary while async replica (node #2) is down.
#
# The galera/galera_2node_slave.cnf describes the setup of the nodes
#

# As node #3 is not a Galera node, and galera_cluster.inc does not open connetion to it
# we open the primary connection her
