-------------------------------------
Summary: Rules in RelDecorrelator not using config of RelBuilder
passed in
Key: CALCITE-7243
URL: https://issues.apache.org/jira/browse/CALCITE-7243
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Steve Carlin
So I think this is a bug, but I'm not sure I have a complete understanding of
the code.
One rule used in RelDecorrelator is on this line:
[https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql2rel/RelDecorrelator.java#L296]
Here, it uses the rule with what seemingly is the RelBuilder that is passed
into the RelDecorrelator as shown in this line:
[https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql2rel/RelDecorrelator.java#L281]
I think the problem is that the RelBuilder needs a Context or a Factory passed
in. It doesn't seem meant to handle a RelBuilder itself?
Not sure how to fix this, but I hit this problem when I needed to use my own
RelBuilder containing a value within my RelBuilder.Config, and it was not using
my RelBuilder in this rule.
