Oleksandr Diachenko commented on HAWQ-1111: ------------------------------------------- As for now HAWQ bridge supports only scalar constant in filter push-down. To support IN operator list constants also needs to be implemented. Convention for * scalar constant: ** c<constant data type>s<number of bytes for constant>d<bytes> * list constant(multiple values): ** m<data type of list items>s<number of item1>d<bytes for item1>s<number of item2>d<bytes for item2>...s<number of itemN>d<bytes for itemN> > Support for IN() operator in PXF > -------------------------------- > > Key: HAWQ-1111 > URL: https://issues.apache.org/jira/browse/HAWQ-1111 > Project: Apache HAWQ > Issue Type: New Feature > Components: PXF > Reporter: Vineet Goel > Assignee: Lei Chang > > HAWQ PXF external tables should be optimized for IN() operator so that users > get the benefit of predicate pushdown. In order to achieve this, HAWQ bridge > must send serialized expression for IN() operator to PXF. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
