I have an UDF (wants/provides = STRAEM) which is executing as I wanted. But at output I get unwanted tags.
I have 2 choices. 1, to select wanted tags while reading and 2, drop unwanted tags in UDF.
As far as I know, I need to use |from().measurement()…
I can not find any other node to select tags for my input stream.
For UDF, I can add new tags using response.point.tags[‘key’] = value
but I dont how to select few tags out of available tags.
Could you please let me know how to solve this?
