------------------------------------
Summary: Support ragged fixed length value union be variable
Key: CALCITE-2321
URL: https://issues.apache.org/jira/browse/CALCITE-2321
Project: Calcite
Issue Type: New Feature
Components: core
Reporter: Hequn Cheng
Assignee: Hequn Cheng
The {{shouldRaggedFixedLengthValueUnionBeVariable()}} function in
{{SqlTypeFactoryImpl}} always return false now. It is good to make it
configurable since some system may need the function to return true to provide
pragmatic behavior.
I see one option to solve this issue: Add {{boolean
shouldRaggedFixedLengthValueUnionBeVariable()}} in {{RelDataTypeSystem}}, so
external system can override to configure the value.
Any suggestions are welcomed. Thanks a lot.
