FWIW, the first thing I noticed is that this will rarely work well, as the index is on a 255length column.
if your table is big, you would definitely see a large improvement by storing a 32char md5 version of that column, creating a partial index on the first 5-8 characters, and then adding a filter to match the partial index too. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
