# === Purpose ===
#
# This test checks the scenarios where the replica applier, when handling a
# table with a GIPK and data from an old source (before version 8.0.30) if
# the source table schema diverges too much in terms of column number there is
# a reported error.
# We also test a scenario where the replica assumes the source has a GIPK when
# it has instead an extra column to the right.
# Positive scenarios are also tested with a valid source table with no GIPK and
# a case where the source table as a key compatible with a GIPK.
#
# ==== Requirements ====
#
# R1. If the replica has a table with a GIPK and the source of replica is below
# 8.0.30, the source table must have the same number of columns or just one less.
#
# === Implementation ====
#
# 1. Create table t1 with a GIPK
# 2. Simulate replication from version 8.0.28 using a generated relay log from that version
# The table on the source only has 1 column, leading to an applier error
# 3. Simulate replication from version 5.7.41 using a generated relay log from that version
# The table on the source has 4 column, leading to an applier error
# 4. Simulate replication from version 8.0.28 using a generated relay log from that version
# The table on the source has 3 column, one extra on the right with a INT type, leading to an applier error
# 5. Simulate replication from version 8.0.28 using a generated relay log from that version
# The table on the source has 2 column, same fields as the replica but no GIPK
# 6. Simulate replication from version 5.7.41 using a generated relay log from that version
# The table on the source has 3 column, with a compatible key similar to a GIPK
# 7. # Clean up
#
