#
# === Purpose ===
#
# This test verifies DMLs are applied on a table by the slave when
# 1. Table on slave has extra generated columns and containing a secondary
#    indexes defined on the generated columns.
# 2. Table on master has generated columns and slave modified the table by
#    changing the generated expressions and adding a secondary index on the
#    generated columns.
#
# === Implementation ===
# Note:
# Aliases used:
# Virtual Generated Column -> VGC
# Stored Generated Column -> SGC
#
# 1. a) Create a table without generated columns.
#    b) Create a table with a VGC and a SGC with secondary indexes defined on
#       them.
#
# 2. a) For 1.a), Add a VGC and SGC with secondary index on the Slave.
#    b) For 1.b), Modify the generated expression for the VGC and SGC on the
#                 Slave.
#
# 3. Perform INSERTs on the tables and validate table data.
#
# 4. Perform UPDATEs on the tables and validate table data.
#
# 5. Perform DELETEs on the tables and validate table data.
