-----------------------------------
Summary: Implement HTTP session support in REST server and client
Key: HBASE-28489
URL: https://issues.apache.org/jira/browse/HBASE-28489
Project: HBase
Issue Type: Improvement
Components: REST
Reporter: Istvan Toth
Assignee: Istvan Toth
The REST server (and java client) currently does not implement sessions.
While is not seem to necessary for the REST API to work, implementing sessions
would be a big improvement in throughput and resource usage.
* It would make balancing with sticky sessions possible
* It would save the overhead of performing authentication for each call
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
perromed on the initial request.
The same change has resulted in spectacular performance improvements for
Phoenix Query Server when implemented in Avatica.
