Work Description: mxm commented on issue #8585: [BEAM-6829] Use transform
name for metric namespace if none provided
URL: https://github.com/apache/beam/pull/8585#issuecomment-537584412
@tweise I've revisited this problem and found two other important fixes in
addition to the first commit:
1. We also need to include PCollection-scoped metrics, e.g. num elements
2. The metric reporting was doubled in ExecutableDoFnOperator. Once by the
operator,
once by the wrapping metrics operator.
In my tests I could not find any duplicate metrics anymore. Plus, the
scoping of the metrics is done correctly, whether it is user metrics, transform
metrics, or pcollection metrics.
