Jesus Camacho Rodriguez created CALCITE-3982:
------------------------------------------------
Summary: FilterMergeRule can lead to AssertionError
Key: CALCITE-3982
URL: https://issues.apache.org/jira/browse/CALCITE-3982
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Jesus Camacho Rodriguez
This could potentially happen since Filter creation has a check on whether the
expression is flat
([here|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/rel/core/Filter.java#L74])
and Filter merge does not flatten an expression when it is created.
