Work Description: robertwb opened a new pull request #6751: [BEAM-5791]
Improve Python SDK progress counters.
URL: https://github.com/apache/beam/pull/6751
The returned metrics are supposed to count the elements consumed, which
should
be incremented after an element is produced, not before. Updated counters
to correctly reflect this, which is important for tracking the rate of buffer
consumption by runners
Also, some runners (e.g. the Dataflow harness) don't set unique names on
PTransforms, which was causing counters to be conflated. Now the counters
use the ptransform_id if the unique name is not provided.

> This is especially important for Fn API reads, where each element represents
> a shard to read and may be very expensive, but many elements may be waiting
> in the Fn API buffer.
> The need for this will be mitigated with full SDF support for liquid sharding
> over the Fn API, but not eliminated unless the runner can "unread" elements
> it has already sent.
