You can sync the data ..from master to slave ..if the table is not
getting good amount of records ..and better to do it when there is
off-peak time ..I mean when there less customer/user incoming data .
You may get some duplicate entry errors on the slave and you can
resolve them by using this following command ..whenever there is
duplicate entry error on the slave.
stop slave; SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; start slave;
