Caching Flashcards

Q
An e-commerce application uses a relational database that runs several queries that perform joins on multiple tables. The development team has found that these queries are slow and expensive, therefore these are a good candidate for caching. The application needs to use a caching service that supports multi-threading.
Why not Redis?
A
Redis does not support multi-threading
Use memcached instead
