Key: IMPALA-12737
URL: https://issues.apache.org/jira/browse/IMPALA-12737
Project: IMPALA
Issue Type: Bug
Reporter: Manish Maheshwari
In the Impala query log table where completed queries are stored, add a list of
all columns andthat were referenced in the query. The purpose behind this
functionality is for to know which columns are part of
* Select clause
* Where clause
* Join clause
* Aggegrate clause
With this information, we will feed into compute stats command to collect stats
only on the required columns that are using in joins / filters and aggegrates
and not on all the table columns.
The information can be collected as an array of
[db1.table1.column1,db1.table1.column2]
