Mark Callaghan 5a8c8845a9 Enhance db_bench ... Summary: Add --benchmarks=updaterandom for read-modify-write workloads. This is different from --benchmarks=readrandomwriterandom in a few ways. First, an "operation" is the combined time to do the read & write rather than treating them as two ops. Second, the same key is used for the read & write. Change RandomGenerator to support rows larger than 1M. That was using "assert" to fail and assert is compiled-away when -DNDEBUG is used. Add more options to db_bench --duration - sets the number of seconds for tests to run. When not set the operation count continues to be the limit. This is used by random operation tests. --use_snapshot - when set GetSnapshot() is called prior to each random read. This is to measure the overhead from using snapshots. --get_approx - when set GetApproximateSizes() is called prior to each random read. This is to measure the overhead for a query optimizer.
