Re: slow query / table lock

Switching to InnoDB gets rid of the table locks of MyISAM. Changing the transaction isolation mode may not be required.

Summary tables would avoid the problem by incrementally building a 'summary' table. Then the query could run much faster against that, instead of hogging the big table.
