> The ArrayBlockingQueue blocks threads for 20s during a performance run
> focusing on creating numerous small scans.
> I see a buffer size of (100)
> private final BlockingQueue<Long> coprocessorTimeNanos = new
> ArrayBlockingQueue<Long>(
> LATENCY_BUFFER_SIZE);
> and then I see a drain coming from
> MetricsRegionWrapperImpl with 45 second executor
> HRegionMetricsWrapperRunable
> RegionCoprocessorHost#getCoprocessorExecutionStatistics()
> RegionCoprocessorHost#getExecutionLatenciesNanos()
> Am I missing something?
