Understanding SQLAlchemy Query Caching for Performance

Optimize application performance with effective caching strategies. Focus on caching frequently read, infrequently updated data like user roles or product categories. Utilize SQLAlchemy with `dogpile.cache` for targeted caching and implement robust cache invalidation methods. Consider shared backends like Redis or Memcached for consistency. Monitor cache performance for continuous improvement.
