Sachin Goel resolved FLINK-2943.
--------------------------------
Resolution: Fixed
> Confusing Bytes/Records "read" and "write" labels in WebUI job view
> -------------------------------------------------------------------
>
> Key: FLINK-2943
> URL: https://issues.apache.org/jira/browse/FLINK-2943
> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 0.10
> Reporter: Fabian Hueske
> Labels: starter
> Fix For: 0.10
>
>
> The job detail view of the WebUI shows the amount of data and records
> received from and sent out by each individual operator. This information is
> very valuable, if correctly interpreted.
> However, the table headings for the corresponding columns ("Bytes read",
> "Records read", "Bytes written", and "Records written") are confusing in my
> opinion because they do not indicate that only incoming and outgoing data is
> tracked and disk IO is not considered at all.
> For example, the UI shows no "Bytes/Records read" and only "Bytes/Records
> written" for DataSources which I find counter-intuitive.
> I propose to rename these labels to either "X received" and "X sent" or "X
> incoming" and "X outgoing" to make clear that this information only affects
> incoming and outgoing data.
> Opinions?
