I just tried clustering the table around that siteid_hostid_index and it did
reduce the number of blocks read from 15000 to 2200 for the query. However,
still running pretty slow (.9 second). I'm beginning to think I need something
more robust than a view. Perhaps I need to build an error_log table that gets
updated via trigger upon insert into log. We shall see.
Thanks,
