to look at the new patch set (#2).
Change subject: [test] Improve the LBM startup benchmark
......................................................................
[test] Improve the LBM startup benchmark
Improve StartupBenchmark test of LBM to support more options.
It's now possible to
* set --startup_benchmark_deleted_block_percentage as double
instead of int to provide more precision value, to simulate
low live block ratio in real world.
* split the benchmark operations into smaller batches which
is controlled by --startup_benchmark_batch_count_for_testing
and --startup_benchmark_block_count_per_batch_for_testing, to
simulate multiple transactions.
* separate the benchmark into independent timing stages include
'init environment', 'create blocks', 'delete blocks',
'shutdown block manager' and 'reopening block manager'.
This is a sub-task of KUDU-3371, we can use the simple benchmark
for following refactors and introduction of storing metadata in
RocksDB to ensure there is no performance degradation.
