    Hi @bowenli86, 
    Me, @zentol and @aljoscha both seem to have doubts about the utility of the feature.
    
    So given this, and to have a clean JIRA and list of PRs we have to work on, I would suggest

    to close the PR and the related issue.

>    Affects Versions: 1.6.0
>            Reporter: Bowen Li

> Motivation: We have the requirements to read a bunch files, each file to read multiple
times, to feed our streams
> Specifically we need {{StreamExecutionEnvironment.readFile/readTextFile}} to be able
to read a file for a specified {{N}} times, but currently it only supports reading file once.
> We've implemented this internally. Would be good to get it back to the community version.
This jira is to add support for the feature. 
> Plan:
> add a new processing mode as PROCESSING_N_TIMES, and add additional parameter {{numTimes}}
for {{StreamExecutionEnvironment.readFile/readTextFile}}
