#
# This include file is used by more than one test suite
# (currently multisource and binlog_encryption).
# Please check all dependent tests after modifying it
#
# Usage:
# --source suite/rpl/include/multisource.inc
#
# By default, the script expects the length of the 2nd binary log to be
# $binlog_start_pos + length(Gtid_list event) + 2 x length(Binlog_checkpoint event)
# Some tests can have specific configuration which would change it, 

#
# Test basic replication functionality 
# in multi-source setup
