Work Description: johnmac-ibm opened a new pull request #430: [BEAM-4177]
Clarify thread contraint in Programming Guide 4.3.2
URL: https://github.com/apache/beam-site/pull/430
As checked on the dev mailing list, the instance will only be active on a
single thread at a time, not the more restrictive single thread ever.
Without clarification, some developers (or runner implementors) may
conservatively assume the constraint is more restrictive than it really is.

> In
> [4.3.2|https://beam.apache.org/documentation/programming-guide/#user-code-thread-compatibility],
> the sentence "Each instance of your function object is accessed by a single
> thread on a worker instance, unless you explicitly create your own threads"
> leaves some ambiguity about whether or not the instance is permanently tied
> to a single thread, or just restricted to being active on a single thread at
> a time.
> I suggest a minor change to:
> Each instance of your function object is accessed by a single thread at a
> time on a worker instance, unless you explicitly create your own threads.
> I will prepare a pull request with this change.
