Supported Version​

MariaDB 10.x

Prerequisites (as a source)​

Enable Binlog​

  • Binlog must be enabled in MariaDB for TapData to complete synchronization work.
  • Cascading delete operations (CASCADE DELETE) generated by the database are not recorded in the binlog and are not supported. Modify $MYSQL_HOME/mysql.cnf, for example:
server_id         = 223344
log_bin           = mysql-bin
expire_logs_days  = 1
binlog_format     = row
binlog_row_image  = full

Restart MariaDB​

/etc/init.d/mysqld restart

Verify that binlog is enabled by executing the following command in the mysql shell:

show variables like 'binlog_format';

The output should show ROW as the value for format.
