Hi,
I have a question regarding mysql master-slave replication's
Relay_Master_Log_File. I hope someone can answer me.
I have mysql setup to purge old logs that arent being used by master, and
also the max log size is set as 500MB. I see that new logs are created with
next number in order.

I searched for a few combination of words, and didnt reach anywhere. Thats

I need to put a read-only copy of a single table on a database on another

This is something I do with replication.
You can replicate a list of tables, see the 'replicate_do_table' config
option.
Then you can euse the 'read_only' option. Replication still works but
nothing else. But it would give you more options by using GRANT instead
of 'read-only':

I use SQLYob Job Agent to synchronise two MySQL databases. See

I use SSH to so port forwarding from one box to the

indexes to the keycache, does it add each index individually or does
it dump the entire .MYI file to the keycache. If it is the latter, I
should move the fulltext index to another table.
