# Test:
# 0. The test requires two servers: M1 and M2.
# 1. With both the members ONLINE. Create a 20 tables on M1.
# 2. Executing the same insert transaction on both server (almost) in parallel,
#    one will be committed, the other will be aborted
# 3. Validate servers state is equal by checking gtid_executed and table data.
# 4. Clean up.
