Write to a memory table first then do a hotcopy on a scheduled basis.

Subject: Possible to delay index writes until server is less busy?
> We've been benchmarking a database that in real-life will have a huge
> write load (max peak load 10000 inserts/second) to the same table
> (MyISAM).
>
> We will need about 4 indexes for that table. However, from our benchmark
> tests, it is clear that writing indexes takes too many resources and
> impedes the speed of inserting new records.
>
> To overcome this, we are thinking of:
> 1 - using several smaller tables (instead of one big one) by creating and
> writing to a new table every x hours,
> 2 - wait with writing the indexes until a new table has been created
> where the next inserts will be (i.e, not write indexes until the table has
> been closed)
>
> The biggest problem now is if the indexes are created when the server is
> very busy. If there was a way of telling MySQL to delay creating the
> indexes when it is busy, then a big obstacle would be out of the way.
>
> Is this possible? We could not find anything in the MySQL documentation
> concerning this.

> Any suggestions would be greatly appreciated.
