-
-explain_log.pl
-
-Feed a mysqld general logfile (created with mysqld --log) back into mysql
-and collect statistics about index usage with EXPLAIN.
-
-=head1 DISCUSSION
-
-To optimize your indices, you have to know which ones are actually
-used and what kind of queries are causing table scans. Especially
-if you are generating your queries dynamically and you have a huge
-amount of queries going on, this isn't easy.
-
-Use this tool to take a look at the effects of your real life queries.
-Then add indices to avoid table scans and remove those which aren't used.
