Jian Feng updated HUDI-4882:
----------------------------
Description:
let's say Stream or Table A
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.
