[jira] [Created] (IMPALA-5738) Make analytic window spillable

Tim Armstrong created IMPALA-5738:
-------------------------------------

             Summary: Make analytic window spillable
                 Key: IMPALA-5738
                 URL: https://issues.apache.org/jira/browse/IMPALA-5738
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.8.0, Impala 2.5.0, Impala 2.6.0, Impala 2.7.0, Impala 2.9.0, Impala 2.10.0
            Reporter: Tim Armstrong
            Priority: Minor


Currently the analytic eval operator supports buffering and spilling its input, but does not support spilling the window (if it is large). 

[~mjacobs] tells me that this is a fairly rare case, but it is one case where the wrong input could cause the operator to use a large amount of memory.
