Caleb Rackliffe commented on CASSANDRA-21177:
---------------------------------------------

They'll take 3x as long, but provide better coverage. {{TrivialSimulationTest}} 
should still be single-digit seconds for 3 iterations. 
{{ShortPaxosSimulationTest}} should still be around a minute. [~shrutips] Let's 
make sure we post the 5.0 and trunk CI results above.

> Adding more randomization, logging to Simulator tests

> Currently Simulator tests use Skiplist memtables and do not have the option 
> to change the memtable type used. We can add the option to randomize between 
> Skiplist and Trie Memtables to test both configurations. Similarly, SSTable 
> format, memtables allocation type have been randomized. Also added explicit 
> logging of randomized options to help debugging test failures, and multiple 
> iterations for tests to improve configuration coverage.
