--------------------------------------

             Summary: Implement the initial framework for caching tuples
                 Key: IMPALA-12818
                 URL: https://issues.apache.org/jira/browse/IMPALA-12818
             Project: IMPALA
          Issue Type: Task
          Components: Backend, Frontend
    Affects Versions: Impala 4.3.0
            Reporter: Joe McDonnell


This tracks introducing the basic concepts of tuple caching. Specifically, it should introduce the TupleCacheNode, which is an ExecNode that can be placed in a plan to cache tuples between existing nodes in the plan. The TupleCachePlanner should place these nodes in locations that are eligible. The TupleCachePlanner is responsible for eligibility as well as producing a cache key.
