You're saying that when you try my example, it does use the composite

If so, do you know of anything in version 4.0.13 that could cause this bad

What I'm trying to do is get the results in the order specified in the "IN"

You are not doing "select count(*)"

> Is it possible to MERGE innodb tables?
No, MERGE is for MyIsam tables only. InnoDb tables are stored in
tablespaces, the problem with file size does not apply. You simply use
multiple tablespaces when the data outgrows the OS limits.
