--------------------------------------

Hi [~jark] [~luoyuxia] I am preparing the 1.20.5 patch release, and there is no 
PR yet, so I moved it to the next patch release. Thanks!

> When {{RowLevelUpdateInfo#requiredColumns}} is specified to some columns 
> (e.g., primary keys), sink function expects to receive the columns values 
> including both the updated columns and primary key column. But sink function 
> only receives the values of primary key columns, which makes update 
> impossible without the updated columns.
