Work Description: mxm commented on pull request #8585: [BEAM-6829] Use
transform name for metric namespace if none provided
URL: https://github.com/apache/beam/pull/8585
In non-portable pipelines, transforms are always scoped by an operator.
Metric
names do not have to be unique across transforms.
In portable pipelines, duplicate metric names inevitably occur if no unique
namespace has been set, due to multiple transforms being fused together
inside a
single operator.
This avoids duplicate metric names by using the transform name as the
namespace,
if none has been provided. It is still possible to provide a custom
namespace.
