I'm on 0.89. Is any of this work in there? I can not use UUIDs, as I need to address rows by key, but I could add a hash of the key to the begining so keys are more evenly distributed. This is of course in case of going to a single table. I filled a 3 node cluster with data (around 6 GB), and the read performance was very bad (lots of LRU flushes and misses). I'll test this approach and see if it works better. Thank you very much!
