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. !image-2022-09-20-22-46-52-907.png! was: 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.
