AI and database index suggestions from query logs
Use LLMs on slow query logs to recommend indexes worth testing.
Creators · AI-Assisted Coding · ~7 min read
The premise
Slow query logs hide patterns; LLMs cluster queries and propose indexes worth benchmarking.
What AI does well here
- Cluster slow queries by table and predicate shape
- Propose composite indexes with expected selectivity
What AI cannot do
- Guarantee an index won't regress writes
- Decide on the storage cost trade-off
Understanding "AI and database index suggestions from query logs" in practice: AI-assisted coding shifts work from syntax recall to design thinking — models handle boilerplate so you focus on architecture. Use LLMs on slow query logs to recommend indexes worth testing — and knowing how to apply this gives you a concrete advantage.
- Apply indexes in your ai-coding workflow to get better results
- Apply query logs in your ai-coding workflow to get better results
- Apply performance in your ai-coding workflow to get better results
- 1Use AI to generate unit tests for an existing function
- 2Ask AI to refactor a messy function and explain the changes
- 3Have AI suggest a code review for a recent pull request

Agents vs. Autocomplete — the Mental Model Shift
Autocomplete is a suggestion. An agent is an actor. The mental model you bring to each is different, and conflating them is the number-one reason teams trip over AI coding.
