[jira] [Work logged] (BEAM-5650) Timeout exceptions while reading a
lot of files from a bounded source like S3 with Flink runner

Work Description: iemejia commented on issue #6952: [BEAM-5650]: Modify BoundedToUnboundedSourceAdapter to configure its reader to read more than 1 bounded source
URL: https://github.com/apache/beam/pull/6952#issuecomment-437017288
Ok some general comments:
- I updated the JIRA ticket to make it more clear now that we know that the issue is related to the way Flink translation works (by using runners-core `UnboundedReadFromBoundedSource`).
- For the comment on tuning `ClientConfiguration` on S3 you can already do that via [S3Options.setClientConfiguration](https://github.com/apache/beam/blob/58372ca8c183f3840fef6d6ec2fab24dd7028475/sdks/java/io/amazon-web-services/src/main/java/org/apache/beam/sdk/io/aws/options/AwsOptions.java#L104).
In general I think the solution makes sense, however I have a bit of doubt if the point where you are fixing it is the correct one, I would like to preserve the current 1-1 relation of unbounded-bounded if possible. (Note that if we can't we will need to update the current documentation because with these changes the semantics has clearly changed).
Thinking a bit this is similar to the Connection/Thread Pool classic problem and I don't know if we may create something similar where the limited 'tasks' are such readers, or if we can just delegate this into native Flink and it will take care. Since I am not a Flink expert I asked @mxm to help us take a look, maybe he knows a better way to proceed..
