Hi, In 99% of use cases Cassandra's row cache is not something you should look into. Leveraging page cache yields good results and if accounted for can provide you with performance increase on read side. I'm not a fan of a default row cache implementation and its invalidation mechanism on updates so you really need to be careful when and how you use it. There isn't much to configuration as there is to your use case. Maybe explain what are you trying to solve with row cache and people can get into discussion with more context.
