             Summary: History Based Optimizer
                 Key: IMPALA-14596
                 URL: https://issues.apache.org/jira/browse/IMPALA-14596
             Project: IMPALA
          Issue Type: Epic
          Components: Backend, Frontend
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


Impala has detailed query profiles which help users to fine-tune the queries 
(using query options or query hints). These infomation can actually be used by 
Impala itself in planning new queries, e.g. fixing wrong estimation, bad join 
order, useless runtime filters, etc.

This Epic tracks the work of adding History Based Optimizer for Impala.
