To optimize Apache Superset performance, follow these best practices:
1. Use a production-ready database: Replace the default SQLite with PostgreSQL or MySQL for better concurrency and scalability.
2. Optimize metadata database: Regularly maintain and tune the metadata database to improve query performance.
3. Leverage caching mechanisms: Utilize Redis or Memcached for caching query results and reduce load on databases.
4. Scale horizontally: Deploy multiple Superset instances behind a load balancer to distribute user traffic evenly.
5. Configure time-outs: Set appropriate time-out limits for queries to prevent long-running tasks from consuming resources.
6. Monitor and analyze logs: Regularly review logs to identify bottlenecks and areas for improvement.
