-----------------------------------
Summary: Add StructKind.PEEK_FIELDS_NO_FLATTENING option to
disable star expansion
Key: CALCITE-1856
URL: https://issues.apache.org/jira/browse/CALCITE-1856
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Shuyi Chen
Assignee: Julian Hyde
We want to use StructKind.PEEK_FIELDS for RecordType. But currently in calcite,
a side effect of using PEEK_FIELDS is that "select *" will recursively flatten
the PEEK_FIELDS RecordType. We want to add an option call
PEEK_FIELDS_NO_FLATTENING to disable the behavior.
