jin xing created CALCITE-3209:
---------------------------------
Summary: Store inputs of MutableMultiRel by ArrayList rather than
ImmutableList
Key: CALCITE-3209
URL: https://issues.apache.org/jira/browse/CALCITE-3209
Project: Calcite
Issue Type: Bug
Components: core
Reporter: jin xing
In current implementation of {{MutableMultiRel}}, {{inputs}} is implemented by
a {{ImmutableList}}, thus impossible to be changed by
https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/rel/mutable/MutableMultiRel.java#L42
{code:java}
@Override public void setInput(int ordinalInParent, MutableRel input)
{code}
Seems a mistake.
