That is a good work around, I appreciate the idea. The optimal would be a
client that listens on the mysql thread the pushes data to the database.
But if there is no way to tap into that thread, the select count(*)
would do.
There must be a way to do it though, since it is done with replication.
Thanks

I'm doing something similar now and I just have my clients (a java app)
periodically check a small table that indicates theres data ready for
them. It's a simple SELECT count(*) ... that is fairly inexpensive
and the does this once every 5 seconds.
I don't know if there is a built-in solution for mysql but this gets the
job done for me.
Let me know if you find a better way to do this.
Thanks,
James

So instead of my client pulling the database on some fixed interval, I
would like the mysql daemon to push the data to my client when there is
new data. I assume this is possible given that it is done with
replication. Does anybody have information on how to implement a client
program like this?
I'm using PHP, but I'm not opposed to using C or C++ for this kind of
functionality.
Thanks.
