Bugs: AURORA-1214
https://issues.apache.org/jira/browse/AURORA-1214
Repository: aurora
Description
-------
With the asynchronous preemptor and a series of other perf improvements, our
scheduling alrorithm perfomance improved 230X - 270X:
Before
```
Benchmark
Mode Samples Score Error Units
SchedulingBenchmarks.InsufficientResourcesSchedulingBenchmark.runBenchmark
thrpt 100 214.098 ± 2.407 ops/s
SchedulingBenchmarks.ConstraintMismatchsSchedulingBenchmark.runBenchmark
thrpt 100 180.754 ± 2.407 ops/s
```
After
```
Benchmark
Mode Cnt Score Error Units
SchedulingBenchmarks.InsufficientResourcesSchedulingBenchmark.runBenchmark
thrpt 10 50328.609 ± 1356.151 ops/s
SchedulingBenchmarks.ValueConstraintMismatchSchedulingBenchmark.runBenchmark
thrpt 10 49237.475 ± 1803.555 ops/s
```
We are only limited by the storage perf now (native + H2). Real life scheduling
round latencies are hovering around 25msec on average (SSD-backed native log
store), which suggests a new default scheduling rate of 40/sec.
