Subject [Impala-ASF-CR] IMPALA-5003: Constant propagation in scan nodes and inline views
Date Mon, 20 Mar 2017 23:46:45 GMT

IMPALA-5003: Constant propagation in scan nodes and inline views

When conjuncts are pushed into table refs and inline views, they can
be considered for constant progagation within that node.

Note: currently broken due to optimizing away column refs for HBase
nodes when FALSE conjuncts are present.  Working on a fix.

Testing: Expanded the test cases for the planner to achieve constant
propagation.  More tests being added (for HBase and Kudu)
