[jira] [Created] (IGNITE-17179) Thin 3.0: SQL metadata caching

Pavel Tupitsyn created IGNITE-17179:
---------------------------------------

             Summary: Thin 3.0: SQL metadata caching
                 Key: IGNITE-17179
                 URL: https://issues.apache.org/jira/browse/IGNITE-17179
             Project: Ignite
          Issue Type: Improvement
          Components: thin client
    Affects Versions: 3.0.0-alpha5
            Reporter: Pavel Tupitsyn
            Assignee: Pavel Tupitsyn
             Fix For: 3.0.0-alpha6


We send query metadata to the client with every request (IGNITE-17052). It is a waste of resources when the same query is executed frequently.

* Cache metadata on server, generate unique ID
* Return the ID to the client
* Client retrieves cached metadata from server when not known, caches it locally
