Aman Sinha created IMPALA-10619: ----------------------------------- Summary: Enable external FE to leverage standardization of first_value/last_value functions Key: IMPALA-10619 URL: https://issues.apache.org/jira/browse/IMPALA-10619 Project: IMPALA Issue Type: Sub-task Components: Frontend Reporter: Aman Sinha Assignee: Aman Sinha
The FIRST_VALUE, LAST _VALUE functions go through standardization process in AnalyticExpr where they may be rewritten with different number of parameters or with different window frame. In order for an external FE to leverage this standardization, some minor changes are needed to allow overriding of creation of a FunctionCallExpr. -- This message was sent by Atlassian Jira (v8.3.4#803005)
