#
# ==== Purpose ====
#
# This test checks if the immediate_commit_timestamp (ICT) and the
# original_commit_timestamp (OCT) are generated and replicated correctly in a
# server_1 (Master) -> server_2 -> server_3 topology, all of them mysql-5.8+
#
# ==== Implementation ====
#
# Considering the previously mentioned replication chain, we make the following
# assertions:
# 1) original_commit_timestamp is the same across all servers
# 2) On the original server, original_commit_timestamp = immediate_commit_timestamp.
# 2) the immediate_commit_timestamp increases as we go down in the topology.
# This assertions are performed in two examples of DDL statements and three
# different DML statements.
#
