Example 1 with CpuTimer

use of io.airlift.stats.CpuTimer in project presto by prestodb.

the class AbstractOperatorBenchmark method runOnce.

@Override
protected Map<String, Long> runOnce() {
    Session session = testSessionBuilder().setSystemProperty("optimizer.optimize-hash-generation", "true").build();
    ExecutorService executor = localQueryRunner.getExecutor();
    MemoryPool memoryPool = new MemoryPool(new MemoryPoolId("test"), new DataSize(1, GIGABYTE));
    MemoryPool systemMemoryPool = new MemoryPool(new MemoryPoolId("testSystem"), new DataSize(1, GIGABYTE));
    TaskContext taskContext = new QueryContext(new QueryId("test"), new DataSize(256, MEGABYTE), memoryPool, systemMemoryPool, executor).addTaskContext(new TaskStateMachine(new TaskId("query", 0, 0), executor), session, false, false);
    CpuTimer cpuTimer = new CpuTimer();
    execute(taskContext);
    CpuDuration executionTime = cpuTimer.elapsedTime();
    TaskStats taskStats = taskContext.getTaskStats();
    long inputRows = taskStats.getRawInputPositions();
    long inputBytes = taskStats.getRawInputDataSize().toBytes();
    long outputRows = taskStats.getOutputPositions();
    long outputBytes = taskStats.getOutputDataSize().toBytes();
    double inputMegaBytes = new DataSize(inputBytes, BYTE).getValue(MEGABYTE);
    return ImmutableMap.<String, Long>builder().put("elapsed_millis", executionTime.getWall().toMillis()).put("input_rows_per_second", (long) (inputRows / executionTime.getWall().getValue(SECONDS))).put("output_rows_per_second", (long) (outputRows / executionTime.getWall().getValue(SECONDS))).put("input_megabytes", (long) inputMegaBytes).put("input_megabytes_per_second", (long) (inputMegaBytes / executionTime.getWall().getValue(SECONDS))).put("wall_nanos", executionTime.getWall().roundTo(NANOSECONDS)).put("cpu_nanos", executionTime.getCpu().roundTo(NANOSECONDS)).put("user_nanos", executionTime.getUser().roundTo(NANOSECONDS)).put("input_rows", inputRows).put("input_bytes", inputBytes).put("output_rows", outputRows).put("output_bytes", outputBytes).build();
