🔗 Detecting full table scans with SQLite

What if you could detect full table scans in SQLite effortlessly? The article dives into how SQLite collects information about prepared statements, allowing developers to figure out if a query caused a full table scan after it was executed. This could have been beneficial for lobste.rs during a recent performance issue. With practical code examples, the author shows how to create a table, insert records, and utilize the statement statistics to check for full scans. By adding indices, the performance improves instantly, as demonstrated with another query. There’s also a thought-provoking suggestion to integrate this functionality into Rails, potentially enhancing the debugging process in development environments.
