Quick Filter "More values ..." runs naive query over huge, unindexed column killing the client/server

Battlestar posted 2 years ago in Feature discussion


The quick filter menu pulls out the most popular values of a given column. This is handy on small (!) tables even when the column isn't indexed. On the other hand, this menu should be disabled when the table is large and/or the column is not indexed because this starts a query which runs literally forever. This causes HeidiSQL to freeze and in some cases we experienced problems with other clients (transaction locking, etc.).

Best regards
