"FlashCache is a general purpose writeback block cache for Linux." We have a case where: - Access to data is not uniformly random (let's say Zipfian). - The "hot" set > RAM. - Size of disk is such that buying enough SSDs, fast drives, multiple drives, etc would be undesirable. This seems like a good case for flashcache. However, as far as I can tell from searching no one has tried this and posted any results. I was wondering if anyone has tried flashcache in a similar situation with Cassandra and if so how the experience went.
