Subject flashcache experimentation
Date Tue, 19 Apr 2011 00:39:57 GMT

"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.
