Chesnay Schepler created FLINK-9599:
---------------------------------------
Summary: 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
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.
