Benedict commented on CASSANDRA-6934:
-------------------------------------
As to benchmarks, CASSANDRA-6553 are the main ones I was using to justify this;
see the green line on [this
graph|http://riptano.github.io/cassandra_performance/graph/graph.html?stats=6553.uber_contention_no_cache_CL_one_4_3.json&metric=op_rate&operation=counterread&smoothing=1&xmin=0&xmax=258.61&ymin=0&ymax=21794.3]
The downside of course is that these numbers are for simple sparse types only -
I need to update stress to support clustering columns (which I plan to do soon)
to create more general graphs for all of the optimisations.

> AbstractCompositeType is called a lot, so deserves some heavy optimisation.
> SimpleCellNameType can be optimised easily, but should explore other
> potential optimisations.
