Omit missing fields in a Mapper
Hi community,
I would like to create a Master Mapper of sorts that will accept an input stream of let’s say field1 and field2, and just output those fields.
Mapper:
TEST_MasterMapper_20...

That’s correct.
I essentially have 25+ data sets to extract from a source system, and from those data sets, there are about 50 common fields.
Hence, a master mapper with the common fields, that will ignore the ‘missing’ fields.
In your example pipeline given, if you enable the Null-safe access in the mapper, then attach another mapper at the end with the expression: $.filter((value, key) => value != null) mapped to the target: $ will give you all the values of your common mappings that are not null.
