@twalthr , for sink only table, I dont think the user need to define any
rowtimes on it, since it will never use as a source. For table as both source
and sink, when registering it as sink, I think we only need to take care of the
'from-field' columns, since they map to actual data fields in the table. For
proctime and 'from-source' columns, we can just ignore them when building the
sink schema. Maybe, we should have some helper method for building the schema
for source and sink separately. Please correct me if I missed something here.
What do you think?
