> Talked with Lars about how we can make it easier for users to run the YCSB
> benchmarks against HBase & get realistic results. Currently, HBase is
> optimized for the random/uniform read/write case, which is the YCSB load.
> The initial reason why we perform bad when users test against us is because
> they do not presplit regions & have the split ratio really low. We need a
> one-line way for a user to create a table that is pre-split to 200 regions
> (or some decent number) by default & disable splitting. Realistically, this
> is how a uniform load cluster should scale, so it's not a hack. This will
> also give us a good use case to point to for how users should pre-split
> regions.
