As part of the Read Committed implementation, nightly testing of YCSB will be adapted to run at the Read Committed isolation level. When doing so, transaction retry loops will be removed from the workload to validate that retry errors are rare or non-existent under weak isolation.

YCSB provides a useful sandbox to test weaker isolation levels because it contains a diverse collection of simple operations run with high contention.
