Make the benchmark scripts configurable and add tests Summary: This makes run_flash_bench.sh configurable. Previously it was hardwired for 1B keys and tests ran for 12 hours each. That kept me from using it. This makes it configuable, adds more tests, makes the duration per-test configurable and refactors the test scripts. Adds the seekrandomwhilemerging test to db_bench which is the same as seekrandomwhilewriting except the writer thread does Merge rather than Put. Forces the stall-time column in compaction IO stats to use a fixed format (H:M:S) which makes it easier to scrape and parse. Also adds an option to AppendHumanMicros to force a fixed format. Sometimes automation and humans want different format. Calls thread->stats.AddBytes(bytes); in db_bench for more tests to get the MB/sec summary stats in the output at test end. Adds the average ingest rate to compaction IO stats.

Make the benchmark scripts configurable and add tests Summary: This makes run_flash_bench.sh configurable. Previously it was hardwired for 1B keys and tests ran for 12 hours each. That kept me from using it. This makes it configuable, adds more tests, makes the duration per-test configurable and refactors the test scripts. Adds the seekrandomwhilemerging test to db_bench which is the same as seekrandomwhilewriting except the writer thread does Merge rather than Put. Forces the stall-time column in compaction IO stats to use a fixed format (H:M:S) which makes it easier to scrape and parse. Also adds an option to AppendHumanMicros to force a fixed format. Sometimes automation and humans want different format. Calls thread->stats.AddBytes(bytes); in db_bench for more tests to get the MB/sec summary stats in the output at test end.

Adds the seekrandomwhilemerging test to db_bench which is the same as seekrandomwhilewriting except the writer thread does Merge rather than Put. Forces the stall-time column in compaction IO stats to use a fixed format (H:M:S) which makes it easier to scrape and parse. Also adds an option to AppendHumanMicros to force a fixed format. Sometimes automation and humans want different format. Calls thread->stats.AddBytes(bytes); in db_bench for more tests to get the MB/sec summary stats in the output at test end. Adds the average ingest rate to compaction IO stats.

Make the benchmark scripts configurable and add tests Summary: This makes run_flash_bench.sh configurable. Previously it was hardwired for 1B keys and tests ran for 12 hours each. That kept me from using it. This makes it configuable, adds more tests, makes the duration per-test configurable and refactors the test scripts.
