> Implement generic mechanism to receive files via rest
> -----------------------------------------------------
>
> Key: FLINK-9599
> URL: https://issues.apache.org/jira/browse/FLINK-9599
> Project: Flink
> Issue Type: New Feature
> Components: REST
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0
>
>
> As a prerequisite for a cleaner implementation of FLINK-9280 we should
> * extend the RestClient to allow the upload of Files
> * extend FileUploadHandler to accept mixed multi-part requests (json + files)
> * generalize mechanism for accessing uploaded files in {{AbstractHandler}}
> Uploaded files can be forwarded to subsequent handlers as an attribute,
> similar to the existing special case for the {{JarUploadHandler}}. The JSON
> body can be forwarded by replacing the incoming http requests with a simple
> {{DefaultFullHttpRequest}}.
> Uploaded files will be retrievable through the {{HandlerRequest}}.
> I'm not certain if/how we can document that a handler accepts files.
