From: Adam Fuchs To: dev@accumulo.apache.org Content-Type: multipart/alternative; boundary=f46d042ef65fe8d36704c3c6e62d --f46d042ef65fe8d36704c3c6e62d Content-Type: text/plain; charset=ISO-8859-1 FATE is really designed to provide low frequency atomic operations across distributed subcomponents components, rather than the high-speed transactions across distributed partitions that Foundation DB supports. Performance in terms of transactions per second is limited with FATE, and certainly doesn't scale linearly as the cluster grows.
