Subject RE: Cassandra vs. Voldemort benchmark
Date Sat, 08 May 2010 04:17:06 GMT
i did a lot of comparisons between voldemort and cassandra and in the end i decided to go with
cassandra.  the main reason was recovery and balancing operations.  on the surface voldemort
is s*** hot fast, until you need to restore a node or add nodes.  BDB (the default persistence
solution) isn't very good at iterating over the entire key space.  it creates a _lot_ of random
seeking across the disk and is therefore very slow.  for small data sets voldemort is a winner
as you can have all your data cached.

(of course i'm not even considering data modeling, just performance on get/put/delete)

i do agree that voldemort and cassandra are first class projects and worthy of many production
deployments.  right tool for the job.
