TWO SAME TABLES, ONE UPDATED. HOW TO SYNC THE OTHER?

Hello

I have two tables -- A and B. The structure of both is the same. Only,
B has many indexes and is used for heavy duty SELECTs. On the other
hand, A only accepts heavy duty INSERTs, so has only one primary key
index.

So my DB design is such that A is only an INSERT table. Periodically,
say every 20 minutes or so, I would like to take all the new INSERTs
from table A and put them into B.

Is there any clever command to accomplish this? I'd rather not write a
PHP script with SQL to take every single new record, and update every
column of a new row in table B. For instance, can I do a replication
of only tables, not databases?

Thanks for any pointers!!
