Ryan Skraba created BEAM-1847:
---------------------------------
Summary: Read.Unbounded can't specify both max records and max
duration.
Key: BEAM-1847
URL: https://issues.apache.org/jira/browse/BEAM-1847
Project: Beam
Issue Type: Bug
Components: beam-model
Reporter: Ryan Skraba
Assignee: Frances Perry
Some Beam IOs that expose the ability to turn an unbounded source into a
bounded source.
For example, KafkaIO uses the underlying Read.from() API to specify the
{{withMaxNumRecords}} and/or {{withMaxReadTime}}. If the former is specified,
the latter is silently ignored.
I would expect that the first stopping condition to be reached (either max
records OR max duration) would stop the source.
The underlying implementation {{BoundedReadFromUnboundedSource}} has this
logic, but it is not supported in Read.Unbounded or the Beam IOs that expose
this feature.
