Assert.assertTrue(metrics.contains(TotalFileSize.name));

Assertions.assertThat(metrics).contains(TotalFileSize.name);

rather than casting here I think what would be better is to provide the necessary type of metrics report in the SparkReadMetricsReporter? This is because report(..) doesn't guarantee that you will only get a ScanReport

What about using Supplier<ScanReport> scanReportSupplier to make this independent from a particular metrics reporter? We can use metricsReporter::scanReport closure to construct it.

InMemoryMetricsReporter metricsReporter = new InMemoryMetricsReporter(); ... scan.metricsReporter(metricsReporter) ... return new SparkBatchQueryScan(..., metricsReporter::scanReport);

Iceberg historically uses null instead of Optional and I think we should continue to follow that. Also, Spotless makes these closures really hard to heard.

What about something like this?

@Override public CustomTaskMetric[] reportDriverMetrics() { ScanReport scanReport = scanReportSupplier.get(); if (scanReport == null) { return new CustomTaskMetric[0]; } List<CustomTaskMetric> driverMetrics = Lists.newArrayList(); driverMetrics.add(TaskTotalFileSize.from(scanReport)); ... return driverMetrics.toArray(new CustomTaskMetric[0]); }

Where TaskTotalFileSize would be defined as follows:

public class TaskTotalFileSize implements CustomTaskMetric { private final long value; public static TaskTotalFileSize from(ScanReport scanReport) { CounterResult counter = scanReport.scanMetrics().totalFileSizeInBytes(); long value = counter != null ? counter.value() : -1; return new TotalFileSizeTaskMetric(value); } private TaskTotalFileSize(long value) { this.value = value; } @Override public String name() { return TotalFileSize.NAME; } @Override public long value() { return value; } }

Is there a reason why we don't include all metrics from ScanMetricsResult?

I had added all metrics from ScanMetricsResult at the point in time when the change was done,
Should we add the remaining now or take in a different PR(since this cange is already reviewed almost)?

Here is a list of the metrics:

TimerResult totalPlanningDuration(); // DONE CounterResult resultDataFiles(); // DONE CounterResult resultDeleteFiles(); // MISSING CounterResult totalDataManifests(); // MISSING CounterResult totalDeleteManifests(); // MISSING CounterResult scannedDataManifests(); // DONE CounterResult skippedDataManifests(); // DONE CounterResult totalFileSizeInBytes(); // DONE CounterResult totalDeleteFileSizeInBytes(); // MISSING CounterResult skippedDataFiles(); // DONE CounterResult skippedDeleteFiles(); // MISSING CounterResult scannedDeleteManifests(); // MISSING CounterResult skippedDeleteManifests(); // MISSING CounterResult indexedDeleteFiles(); // MISSING CounterResult equalityDeleteFiles(); // MISSING CounterResult positionalDeleteFiles(); // MISSING

Can be done in a follow-up.

+1, this seems to be a generic container allowing to intercept a report.

I'd also call it InMemoryMetricsReporter, there is nothing specific to reads right now.

We also should use Metrics vs Metric in the name to match the interface.

+1 to both suggestions

We would probably need to check built-in Spark metrics as a reference. It will probably be 0 in other cases as Spark passes an empty array of task values and then does sum on it.

Making it 0 based on this
