WSO2 ESB Cache mediation to cache a config file

Question

I need to get some configs from a my xml config file. Due to the high load it is a bad idea to read data from file for each proxy service invocation. I found smooks and cache mediators and I think these two mediators can help me but I don't know how. Also I've heard of VFS transports but since I have the large scale and high load of requests I have to reduce the service invokation or reading from files and handle this problem with some cached data in server RAM.

How about using a database to build a persistent cache, so that you can do a dblookup before reading the file. This mediation logic can be defined within the ESB where the ESB will do a DBlookup before accessing the file. Similarly for a new entry you can create a cache entry in the DB.
