[jira] [Created] (HUDI-4882) Multiple ordering fields for partial update

Jian Feng created HUDI-4882:
-------------------------------

             Summary: Multiple ordering fields for partial update
                 Key: HUDI-4882
                 URL: https://issues.apache.org/jira/browse/HUDI-4882
             Project: Apache Hudi
          Issue Type: New Feature
            Reporter: Jian Feng
         Attachments: image-2022-09-20-22-42-19-445.png, image-2022-09-20-22-46-52-907.png

This feature will allow users to perform partial updates across sub-tables/sources by determining the state of a set of columns in a row based on an ordering/precombine column.

As such, a table can have MULTIPLE ordering fields.

This use case is suitable for wide Hudi tables that are created from smaller sub-tables, where each of its sub-tables has its own precombine column, and where its records could be upserted out of order.
