Owen O'Malley commented on HIVE-19902:
--------------------------------------
[~akolb], thanks for the answers.
JMH does provide the functionality for benchmark setup/teardown. It looks like:
{code}
@BenchmarkMode(Mode.AverageTime)
@Warmup(iterations=2 time=5, timeUnit = TimeUnit.SECONDS) // 2 iterations of 5
seconds each
@Measurement(iterations=10, time=5, timeUnit = TimeUnit.SECONDS) // 10
iterations of 5 seconds each
@OutputTimeUnit(TimeUnit.MICROSECONDS)
@Fork(1)
public class MetastoreBenchmarks {
@State(Scope.Thread)
public static class MyState {
... variables and parameters that benchmarks need ...
@Setup(Level.Trial)
public void setup() {
.. unmeasured setup code ...
}
@TearDown(Level.Trial)
public void teardown() {
... unmeasured teardown code ...
}
}
@Benchmark
public void testMethod(MyState state) {
... code to be benchmarked ....
}
}
{code}
