OtterTune is a tool from the CMU Database Group that automatically finds good settings for a DBMS's configuration knobs using machine learning. It reuses training data from previous tuning sessions to drastically reduce tuning time for new database deployments.
Use cases
- automatically tune postgresql configuration knobs
- optimize mysql settings without a DBA
- find best database configuration with machine learning
- reduce database tuning time using prior tuning data
- tune dbms performance parameters automatically
When to choose
- you want automated DBMS knob tuning without database administration expertise
- you can run a self-hosted tuning service against your database
- you want to leverage ML models trained on prior tuning sessions
When to avoid
- you need actively maintained software - the last release was 2020 and the project is research-oriented
- you want a managed cloud tuning service (the commercial OtterTune product is separate)
- you need support for DBMSs beyond those the tool targets
