Query Query Query
by in CodeSOD on 2024-04-24Bob's employer had a data-driven application which wasn't performing terribly well. They had some in-house database administrators, but their skills were more "keep things running," and less "do deep optimizations". The company opted to hire a contract DBA to come in, address the performance problems, and leave.
In actual fact, the DBA came in, ran some monitoring, and then simply wrote some guidance- generic, and frankly useless guidance. "Index on frequently queried fields," and "ensure database statistics are gathered on the appropriate schedule."
