Ed Espino updated HAWQ-1049:
----------------------------
Labels: (was: ToBeClosed)
> Enhance PXF Service to support AND,OR,NOT logical operators in Predicate
> Pushdown
> ---------------------------------------------------------------------------------
>
> Key: HAWQ-1049
> URL: https://issues.apache.org/jira/browse/HAWQ-1049
> Project: Apache HAWQ
> Issue Type: Sub-task
> Components: PXF
> Reporter: Shivram Mani
> Assignee: Kavinder Dhaliwal
> Fix For: 2.1.0.0-incubating
>
>
> Support additional logical operators OR, NOT along with currently supported
> AND.
> Update the PXF ORC Accessor to support these opearators as well.
> Currently PXF only receives filters as a list of AND expressions. In
> anticipation of HAWQ-1048, PXF needs to support parsing a filter string that
> includes AND, OR, and NOT operators. The proposal for doing so is to
> introduce a special character 'l' for logical operators. With the following
> operations
> AND='0'
> OR='1'
> NOT='2'
> Thus the filter string
> 'a1c2o0a2c5o2l1' would translate to Column 1 < 1 OR Column 2 > 5
