> I'm trying to write an XML file where the source is a text file stored in GCS. The code
is running fine but instead of a single XML file, it is generating multiple XML files. (No.
of XML files seem to follow total no. of records present in source text file). I have observed
this scenario while using 'DataflowRunner'.
> When I run the same code in local then two files get generated. First one contains all
the records with proper elements and the second one contains only opening and closing root
element.
> As I learnt,it is expected that it may produce multiple files: e.g. if the runner chooses
to process your data parallelizing it into 3 tasks ("bundles"), you'll get 3 files. Some of
the parts may turn out empty in some cases, but the total data written will always add up
to the expected data.
