Kavinder Dhaliwal updated HAWQ-1049: ------------------------------------ Fix Version/s: (was: backlog) > 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 > > 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
