Ismaël Mejía commented on BEAM-2046:
------------------------------------
Huge +1, also it would be nice a method that receives a list (or vargs) of
names in a namespace and return a map with the associate existing values for
the given metrics.
> Better API for querying metrics

> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-core

> I just want to read a metric :-).
> Can we have a better API than this:
> Iterable<MetricResult<Long>> seenMetrics = job.metrics()
> .queryMetrics(
> MetricsFilter.builder()
> .addNameFilter(MetricNameFilter.named("XX", "YY"))
> .build())
> .counters();
> long seenSentinels = Iterables.isEmpty(seenMetrics) ? 0
> : Iterables.getFirst(seenMetrics, null).committed();
> This is very clunky :-P.
> Ideally I'd like to read a metric with a name, and provide a default value if
> the metric is not there.
