[jira] [Created] (IMPALA-11461) Codegen Caching for low latency queries

Abhishek Rawat created IMPALA-11461:
---------------------------------------

             Summary: Codegen Caching for low latency queries
                 Key: IMPALA-11461
                 URL: https://issues.apache.org/jira/browse/IMPALA-11461
             Project: IMPALA
          Issue Type: Epic
            Reporter: Abhishek Rawat


It probably makes sense to have an in-memory local cache per Impala coordinator/executor node, especially for low latency queries whose codegen time is a huge chunk of overall elapsed time.
