--- Test scenario one starts from here
--- 1. table_first and table_second are colocated tables.
--- 2. myuser is the owner table_first and admin_user is the owner of table_second.
--- 3. Shard table_first_4 and table_second_7 are colocated on worker1
--- 4. table_first_4 is split into table_first_5 and table_first_6 with target as worker2
--- 5. table_second_7 is split into table_second_8 and table_second_9 with target as worker2
--- 6. Create two publishers and two subscribers for respective table owners.
--- 7. Insert into table_first_4 and table_second_7 at source worker1
--- 8. Expect the results in child shards on worker2
