-------------------------------------
Summary: Ensure Samza SQL rel message column order
Key: SAMZA-2573
URL: https://issues.apache.org/jira/browse/SAMZA-2573
Project: Samza
Issue Type: Sub-task
Reporter: Slim Bouguerra
Ensure that the Calcite Schema top level column order is the same as the Samza
input Rel Message.
This is an important item for the following reasons:
* Calcite Query translation and planning relies on column index to access or
generate expression hence it is a critical task to ensure that the order of
physical column and schema is the same.
* Once remote tables add the support of listing for primary key column, it
becomes important to break the assumption that the __key__ column is always at
index 0.
