------------------------------------------
Summary: Calcite engine. Index can't be used with IS NULL condition
Key: IGNITE-16085
URL: https://issues.apache.org/jira/browse/IGNITE-16085
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Currently, we support only {{EQUALS}}, {{LESS_THAN}}, {{GREATER_THAN}},
{{GREATER_THAN_OR_EQUAL}}, {{LESS_THAN_OR_EQUAL}} conditions for index scans.
Our indexes also can be scanned for null values by design, but full table scan
now performed for {{IS NULL}} condition on indexed fields.
