[jira] [Created] (CALCITE-4152) Avoid SPNEGO re-negotiation for each request

Istvan Toth created CALCITE-4152:
------------------------------------

             Summary: Avoid SPNEGO re-negotiation for each request
                 Key: CALCITE-4152
                 URL: https://issues.apache.org/jira/browse/CALCITE-4152
             Project: Calcite
          Issue Type: Improvement
          Components: avatica
            Reporter: Istvan Toth


When using SPNEGO authentication with Avatica, every HTTP request re-initiates the negotiation, doubling the number HTTP requests.

Consider switching to cookies after the initial SPNEGO authentication succeeds.
