Question

Never used a cache like this before. The problem is that I want to load 500,000 + records out of a database and do some selecting/filtering wicked fast.

I’m thinking about using a cache, and preliminarily found EHCache and OSCache, any opinions?

Answer 1

They’re both pretty solid projects. If you have pretty basic caching needs, either one of them will probably work as well as the other.

You may also wish to consider doing the filtering in a database query if it’s feasible. Often, using a tuned query that returns a smaller result set will give you better performance than loading 500,000 rows into memory and then filtering them.
