Hi All, I’m working on a calcite adapter and I’m hitting issues with handling array columns. I’m seeing NullPointerExceptions from queries like “SELECT * FROM table WHERE list IS EMPTY” when “list” is a nullable column. I think the root cause here might be the NullPolicy for the IS_EMPTY operator in RexImpTable? I’m thinking this should probably be NullPolicy.STRICT and not NullPolicy.NONE, and therefore not shortcircuiting the null check on the collection before calling isEmpty()?
Thanks, Chris
