Subject Re: Decision Making- YCSB

There are many YCSB forks on github that get optimized for specific
databases but the default one is decent across the defaults. Cassandra
has it's own internal stress tool that we like better.

The short comings are that generic tools and generic workloads are
generic and thus not real-world. But other then that being able to
tweak the workload percentages and change the read patterns from
latest/random/etc does a decent job of stressing normal and worst-case
scenarios on the read path. Still I would try to build my own real
world use case as a tool to evaluate a solution before making a
