No but that would be dirt simple. I'd just create a utility that would gzip string value on put and unzip it when you get an item. This would only help if the items were very large and not frequently accessed. If you access them a lot, the CPU costs may not be worth it. If you don't access them much, then you might as well put them in a disk only region. In that case, compression might make access a bit faster if the items were very big. It would also save disk space, etc . . . . But this is pretty special case.
For example, I cache compressed XML that would be several megabytes as a string. One application I'm working on has a partitioned distributed remote cache backed by the myslql disk cache. There are 4 partitions, each with 2 servers, a primary and a failover remote server in cluster mode. Hence 8 machines running the remote server and mysql. (Each partition is a different region in the cache.ccf configured to use a different remote auxiliary. The key is numeric. We determine the partition by taking the modulus of the key and the number of partitions.) The data only lives a short time (30 minutes), but there is lots of it: ~12 GB's every 30 minutes compressed. There is no way I could cache this data as Strings or serialized objects. Basically, I'm caching the response from a downstream service. My service returns part and clients of my service can request additional results from a previous query. This requires going to the cache, getting the compressed XML, unmarshalling it, etc. I have a simpler app that has only 1 node (2 remote servers in cluster mode). It handles 12 million small puts and about the same gets a day. Here the Items are 1 to 3k. They are serialized objects, not compressed XML. I didn't have to make the same tradeoffs here. . . .
