Andy, there’re multiple reasons. Foremost, in most cases you need connection pooling for prepared statements to be useful, as they get lost on disconnect. As connection costs with C API are minimal, keeping connections open on the server doesn’t seem to be too useful. And you really don’t want to hold connections from every Apache/PHP process you have open to each of your servers. Thats a lot of connections, for not that much effect.

Also, people in scripting language world love creating dynamic statements (even as simple concept a variable length IN() list cannot work with prepared statements…) – and that again doesn’t work that well with PS.

Also, to execute a new prepared statement you need two queries – one to prepare, other to execute, so you really really want to cache them in one way or another.

Why do you think that Prepared Statements don’t make much sense in PHP/C environments?

That is an excellent reason for 3 backup db servers. Too many assumptions about redundancy require people and the utilities they use during an outage to be perfect.

What features do you want to see in MariaDB?
