A lot is wrong with it.
It's a) not generic, b) requires modification to the parser for
something that is inherently a plugin's functionality, and c) embeds
the
word BINLOG and WRITE into the command, which means we tie
*implementation specifics* to the *interface*, which is entirely
against
Drizzle's goals.
Now, a solution such as this:
SET @replicator.enabled= FALSE;
/* do some commands... */
SET @replicator.enabled= TRUE;
would be perfectly sensible to me.

All,
As I was hacking on the new replication code today, I noticed that
Drizzle (and MySQL 6) is passing through REPAIR, OPTIMIZE, and
ANALYZE
TABLE statements as-is into the binlog and the replication stream.
Oddly, CHECK TABLE is not replicated. ?.
That doesn't seem odd at all to me.
You use "CHECK TABLE" to see if a "REPAIR" is needed. If you end up
needing to run the repair on your master, you may or may not want
to run it
on your slaves (and have that control). But I can't see a need to
every
blindly fire off "CHECK TABLE" commands at slaves.
Can anyone else?
Question: Should any of these statements be replicated or sent to a
binary log?
REPAIR, OPTIMIZE, and ANALYZE should. If I want to run them on
the master
only, I can use "SET SQL_LOG_BIN=0" to get that (though I wish
there was a
cleaner syntax to disable for ONLY the next command).
Should Drizzle replicate any administrative commands at all?
Personally, I don't see the value in replicating them or storing
them in
a recovery log either...but...input is always welcome!
It's very useful to have that option as a sever admin (or someone
who tries
to tell them what to do).
