Moving data from HEAP table to KEY partitioned ISAM table - advice needed

Hi.

I need some advice.

I currently have a db that in it's main table has around 3.2M entries. This will soon grow to 100M.

This table is currently held in a heap table.

I don't think it's going to be feasible to continue to have this table in memory as it grows to 100M therefore I'm exploring putting it in a regular ISAM table but using KEY partitioning.

The two fields in my table are as follows:
domID(int 10)
domain(varchar 70)

99% of all the searches will be done on the domain field in this table.

My question is will KEY partitioning the table give me any performance increases as opposed to a non-partitioned ISAM table?

Bear in mind that most searches on the domain field will be using LIKE, so from my limited understanding a full table scan will be required anyway.

I'm hoping though that it's quicker for MySQL to perform a full table scan on 20 or so partitions rather than on a regular non-partitioned table?

Also, does anyone know if you can partition a heap table?

Many thanks!

Simon
