# Test binlog variants produced by Ndb

# 1) Updates logged as write_row events
# Only primary key and updated columns included in the
# event
# 2) Updates logged as write_row_events
# All columns included in the event
# 3) Updates logged as update_row events
# Only primary key and updated columns included in the
# event
# 4) Updates logged as update_row events
# All columns included in the event
#
# Format variant (1) is the Ndb default.
#
# We use mysqlbinlog --verbose to check that the
# generated binlog contents are as expected.

# Bug#46662
# Replicating changes to tables with unique indexes
# The fix to bug#27378 results in the slave using NdbApi's write()
# mechanism when applying WRITE_ROW events to tables with unique
# indices.
#
# If this is not done then the slave attempts to partially use SQL
# REPLACE semantics when applying WRITE_ROW events to tables with
# unique indexes, which is not good and the slave fails with a
# duplicate key error on the primary key.
#
# The fix to Bug#46662 aims to correct this, so that replicated
# updates to tables with unique indices can work.
# Note that other issues with replicating into tables with unique
# indexes remain.
