>                 URL: https://issues.apache.org/jira/browse/HBASE-28489
>             Project: HBase
>          Issue Type: Improvement
>          Components: REST
>            Reporter: Istvan Toth

>
> The REST server (and java client) currently does not implement sessions.
> While is not  necessary for the REST API to work, implementing sessions would be a big improvement in throughput and resource usage.
> * It would make load balancing with sticky sessions possible (though it's not really needed for REST)
> * It would save the overhead of performing authentication for each request
>  The gains are particularly big when using SPENGO:
> * The full SPENGO handshake can be skipped for subsequent requests
> * When Knox performs SPENGO authentication for the proxied client, it access the identity store each time. When the session is set, this step is only perfomed on the initial request.
> The same change has resulted in spectacular performance improvements for Phoenix Query Server when implemented in Avatica.
