Description

MySQL-MySQL incr stage: use mapping and filter like cause src dtle panic

Steps to reproduce the issue

  1. prepare data
sql> CREATE DATABASE IF NOT EXISTS `action_db_1`;
shell> sysbench /usr/share/sysbench/oltp_common.lua --mysql-host=172.100.9.3 --mysql-port=3306 --mysql-user=test --mysql-password=test --create_secondary=off --report-interval=10 --time=0 --mysql-db=action_db_1 --tables=1 --table_size=5000 prepare
  1. create dtle job

    }
  }
}
  1. check data count
  2. execute sql on src MySQL
shell> sysbench /usr/share/sysbench/oltp_write_only.lua --mysql-host=172.100.9.3 --mysql-port=3306 --mysql-user=test --mysql-password=test --create_secondary=off --report-interval=10 --time=0 --mysql-db=action_db_1 --tables=1 --table_size=5000 --events=15000 --rand-type=uniform run
  1. check data count
# src MySQL
sql> SELECT COUNT(*) FROM sbtest1 WHERE c LIKE '1%';
{'COUNT(*)': 501}
# dest MySQL
sql> SELECT COUNT(*) FROM sbtest1_rename WHERE c LIKE '1%';
{'COUNT(*)': 461}
  1. just filter use like can't trigger panic

Describe the results you expected

The amount of data is consistent
