Shuo Cheng updated FLINK-23962:
-------------------------------
    Description: 
For sql jobs with multi-sinks, the plan is divided into relNode blocks, 
changeLog mode should be also inferred among blocks. Currently, updateKind 
trait is not propagated properly from parent block to child blocks for the 
following pattern.

 

block0 -> block1 -> block3

            \-> block2

 

In the above example, block3 requies UB, block2 does not require UB.

For Agg in block0, UB should be emitted, but the updateKind for block0 is 
inferred as 

ONLY_UPDATE_AFTER.
