Also,
run "SHOW PROCESSLIST", to see what sql's are running on slave.
This will give u any idea if any huge dml was run on master and its getting
sync'd with slave.

A few things to keep in mind:
1: the master may have several threads feeding into the binlog at a time,
but a slave only executes in a single thread. Are you throwing more stuff
at the slave in multiple mysql threads?
2: is there something else going on with the slave box? some big backup or
gz
Good day :)
We've had our master/slave server running for a while now, and just
yesterday, we started getting behind.
Not entirely sure what happened, but it is getting further and furhter
behind.

Hi,
MySQL replicate the databases at SQL level, so if the two servers are
using the same engine (innodb), they will be replicated without
problems.
If the BLOB data is big, don't configure the replication over a WAN or
you will get too much latency (of course, it depends on your
bandwidth).

I know the master/slave replication scheme for MySQL is pretty easy to
set up; I'm doing it lab now. My question is does anyone know if it
will successfully replicate foreign key constraints and large BLOB
date types.
Any feedback on this would be gratefully appreciated.

You can determine the server actions by looking through the slave log
file.

Subject: Re: MySQL slave error when creating view
Sounds like a bug to me. It's likely fixed in newer versions; a lot of
view/function/sproc replication bugs have been fixed. But if not, you should
report it.
