add index to slave but not master

Re: add index to slave but not master
Functionally not a problem. Many people use a slave for different work loads then their master. Different indexes for different queries make sense. Be aware that should you intend to make backups off the slave or even leave yourself open to promoting slave to master as a HA strategy then things will differ from the original master and you might notice a performance difference as a result.

Re: importing mysql structures only or restore ignoring non-existing tables and columns?

I know there's an option to expert structures only. (like –no-data) Is there a way (except 3rd party software like mysqldiff.org) to import structure only to an existing data? Alternativley, is there a way to import only data ignoring non-existing tables and colums? (I thought this may do the trick if I back-up data - import structure - restore the data.) You can use SELECT...INTO DUMPFILE and LOAD DATA INFILE... to achieve what I believe you're asking here, save the eventual misunderstanding. ;-) Cheers -- Luis Motta Campos is a DBA, Foodie, and Photographer -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Jeff, I manage some big data here and this is my preferred strategy - shard the workload in different mysql pools (behind a load balancer) and give each different pool a different, custom-tailored index set optimized for the workload expected. Be warned that if you promote a new master without ensuring index-compatibility with the master workload you will (obviously) observe performance variations. Good luck.
