Subject [jira] [Created] (IGNITE-5482) Implement basic caching of query results
Date Wed, 14 Jun 2017 00:24:00 GMT
Alexander Paschenko created IGNITE-5482:

             Summary: Implement basic caching of query results
                 Key: IGNITE-5482
                 URL: https://issues.apache.org/jira/browse/IGNITE-5482
             Project: Ignite
          Issue Type: Task
          Components: sql
    Affects Versions: 2.0
            Reporter: Alexander Paschenko
            Assignee: Alexander Paschenko
             Fix For: 2.1

Sergi suggested that we reuse results of the same queries running simultaneously - i.e. if
a query is being executed with the same arguments and flags again and again, there's no need
to do actual querying of data, instead we can really run query once while other simultaneous
runs will wait for those results.

This strategy will be implemented on MAP stage of distributed query.
