GitHub user dave-csc added a comment to the discussion: How to transpose a
stream for logging?
Hi @liosc,
I kinda solved... at least for logging: I haven't made an actual transpose of
the stream.
I used a **Token replacement** transform to compose the log lines like
`${origin} = ${origin_count}`. Then I linked a **Group by** transform to
concatenate the lines in a block, using `$[0A]` (new line) as separator.
A solution to use Row denormaliser even if I'm not full aware of the possible
key values is still welcome... anyway, thanks for the hint :)
