-----------------------------------------
Summary: SQL Client gateway mode should accept URLs
Key: FLINK-32030
URL: https://issues.apache.org/jira/browse/FLINK-32030
Project: Flink
Issue Type: Improvement
Components: Table SQL / Client, Table SQL / Gateway
Affects Versions: 1.17.0
Reporter: Alexander Fedulov
Assignee: Alexander Fedulov
Currently, the _--endpoint_ parameter has to be specified in the
_InetSocketAddress_ format, i.e. _hostname:port._ While this works fine for
basic use cases, it does not support the placement of the gateway behind a
proxy or using an Ingress for routing to a specific Flink cluster based on the
URL path. I.e. it expects
_[some.hostname.com:9001|http://some.hostname.com:9001/]_ to directly serve
requests on _[some.hostname.com:9001/v1|http://some.hostname.com:9001/v1]_ .
Mapping to a non-root location, i.e.
_[some.hostname.com:9001/flink-clusters/sql-preview-cluster-1/v1|http://some.hostname.com:9001/flink-clusters/sql-preview-cluster-1/v1]_
is not supported.
Since the client talks to the gateway via its REST endpoint, the right format
for the _--endpoint_ parameter is {_}URL{_}, not _InetSocketAddress_ .
