> REST Catalog dispatch implementation for including configurable metadata as
> outbound request headers
> ----------------------------------------------------------------------------------------------------
>
> Key: KNOX-3279
> URL: https://issues.apache.org/jira/browse/KNOX-3279
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Reporter: Philip Zampino
> Assignee: Philip Zampino
> Priority: Major
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> For Iceberg REST Catalog proxying, Knox should support the ability to convey
> a configurable set of token metadata elements associated with the client
> credentials from the inbound request as headers in the outbound (dispatch)
> request.
> A custom dispatch for the ICEBERG-REST service should be implemented to
> provide this support.
> Proposed topology contents (example):
> {code:java}
> <service>
> <role>ICEBERG-REST</role>
> <param>
> <name>token-metadata-headers</name>
> <value>email,category</value>
> </param>
> </service> {code}
> If the configured metadata items don't exist for a given client_id, then no
> headers for those items should be conveyed in the outbound request (i.e.,
> they should be ignored).
>
> It's not clear whether the standard {{userName}} metadata item should be
> included by default.
> The resulting header names can be of the form {{X-Knox-Meta-<ITEM_NAME>}}
> where {{<ITEM_NAME>}} is the token metadata item name.
