# === Purpose === # # This test verifies that ORDER BY on replication pfs tables returns # the correct data set. # # === Implementation === # # 1) Setup a multi-source replication topology. # 2) With STS, execute DDLs on both the masters and use SQL ordering # on PFS tables on slave. # 3) Repeat step 2 with Multi-threaded Slave. # # === References === # Bug #22958077: ORDER BY LAST_SEEN_TRANSACTION RESULTS IN EMPTY SET (OR DEBUG # ASSERTION) --let $rpl_topology= 3->2,1->2 --let $rpl_multi_source= 1 --let $rpl_skip_start_slave= 1 --source include/rpl_init.inc --let $rpl_connection_name= server_2 --source include/rpl_connection.inc SET @save.slave_parallel_workers= @@global.slave_parallel_workers; --echo # Test for Single Threaded Slave SET GLOBAL slave_parallel_workers= 0; START SLAVE; --source extra/rpl_tests/rpl_perfschema_order_by.test --echo # Test for Multi Threaded Slave STOP SLAVE; SET GLOBAL slave_parallel_workers = 2; START SLAVE; --source extra/rpl_tests/rpl_perfschema_order_by.test #Cleanup STOP SLAVE; SET @@global.slave_parallel_workers= @save.slave_parallel_workers; START SLAVE; --let $rpl_skip_sync= 1 --source include/rpl_end.inc
