I have a web service that has ~1k request threads running simultaneously on average. These threads access data from a cache (currently on ehcache.) When the entries in the cache expire, the thread that hits the expired entry tries getting the new value from the DB, while the other threads also trying to hit this entry block, i.e. I use t...
I have 2 functions: first public String doA(Integer userId, String someValue) that I want to cache (taking into account parameters of function), and second public String doB(Integer userId) that should drops cache of function "doA" for current userId. Does Ehcache support something like memcached tags or anything other that can he...
Hi, The question might sound vague but I'm trying to understand the general concept of the EHCache transaction ability.

I don't want ehcache to keep the resized image in memory; neither when cached or when being read in. How do I make ehcache only store on disk (no me...
Hi folks, I have what I would assume is a pretty standard setup...spring, jpa (hibernate) and I'm trying to add ehcache. I have it all configured and verified that it's working...I'm logging the hibernate sql statements and cache statements and can see that the cache is getting invoked and that once the object is in the cache, when I t...
Probably it is a basic question, but could not found the answer anywhere in the web. I am trying to use a second level cache (using ehcache) and just checked that some objects were being retrieved from database every time I tried to load them, the only difference was that I was not getting them by id but by a property that carries a SE...
