-------------------------------------
Summary: Simplification of a filter =($0, false) to NOT($0) ($0 is
boolean)
Key: CALCITE-2934
URL: https://issues.apache.org/jira/browse/CALCITE-2934
Project: Calcite
Issue Type: Bug
Reporter: Stamatis Zampetakis
Fix For: 1.20.0
The errors occur due to the simplification of a filter =($0, false) to NOT($0)
($0 is boolean). The transformation is valid so in principle the tests should
not fail. However it makes me wonder if adding negation is really a
simplification. If I want to push this expression into an index
(e.g., B+Tree) I would have to rewrite it again to something equivalent to
=($0, false) since many types of indexes do not support negative conditions.
