Maxim Khutornenko created AURORA-1324:
-----------------------------------------
Summary: Reevaluate the effectiveness of DBStorage.bulkLoad()
Key: AURORA-1324
URL: https://issues.apache.org/jira/browse/AURORA-1324
Project: Aurora
Issue Type: Task
Components: Scheduler
Reporter: Maxim Khutornenko
The bulkLoad() functionality added in https://reviews.apache.org/r/33273/ does not seem to yield any noticeable gain after the MV_STORE was disabled:
{noformat}
with bulkLoad():
Benchmark (updateCount) Mode Cnt Score Error Units
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 1 thrpt 5 14.775 ± 3.761 ops/s
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 5 thrpt 5 3.069 ± 0.427 ops/s
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 10 thrpt 5 1.467 ± 0.058 ops/s
without bulkLoad():
Benchmark (updateCount) Mode Cnt Score Error Units
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 1 thrpt 5 15.042 ± 1.624 ops/s
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 5 thrpt 5 2.876 ± 0.481 ops/s
SnapshotBenchmarks.RestoreSnapshotWithUpdatesBenchmark.run 10 thrpt 5 1.496 ± 0.050 ops/s
{noformat}
Consider removing DBStorage.bulkLoad().
