Carefully constructed SQL triggers could be used to maintain accurate cached counts for a table, by incrementing and decrementing a counter every time a row is inserted or deleted.

`sqlite-utils` already has a mechanism for creating triggers for FTS - the `table.enable_fts(..., create_triggers=True)` method. How about a similar mechanism for setting up triggers to maintain a count of table rows?",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/212/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
