Tobias Feldhaus commented on BEAM-1714:
---------------------------------------
Sorry that I didn't manage to come up with a testcase and answer yet, due to a
shortage of time on my side.
Thank you for clarifying this!
When the recommended way is to not omit these values at all, how would I
transform a deserialized JSON that is read line by line from a file, where
values can be null, most efficiently?
I thought about using the Stream API in Java8, stream all class fields and
filter out those that are not null, then using the remaining ones to set the
TableRow object.

> When outputting a TableRow that has a Null value for a key, a Null Pointer
> Exception is thrown. In the Dataflow SDK (1.9) this case is handled by
> outputting NULL for that field.
> I would expect the same behavior from the Beam SDK - since otherwise there is
> always a lot of Null checking necessary in the user code. (Especially when
> there are nested fields.)
