Discussion with Caterina Pintilie

Hello! I have a question about optimizing the query for the logs table. The composite index on (timestamp, user_id) doesn't seem to be used as we expected.
14:02
Can I send the execution plan? It shows a full scan is being performed.
14:05
Yes, please. Also check if the column statistics are up to date. Sometimes the optimizer chooses a scan if the data is outdated.
14:07
Correct! The statistics were old. After `ANALYZE`, the index is used. Performance increased by ~85%. Thank you!
