Rrdcached package?

Hi i am using rrdtool to store statistics. Now i want to minimize wear on the mmc card. I need rrdcached package to limit writes to like once an hour. Has anyone seen a rrdcached package?


rrdcached is a daemon that receives updates to existing RRD files, accumulates them and, if enough have been received or a defined time has passed, writes the updates to the RRD file"
