My requirement is to concatenate all the values of all fields in a document.
Name — runtime value Naidu
Addr1 — this field is an empty value
Addr2 — runtime value India
The output must be Naidu||India
i.e all the filed values concatenated with a seperator |. Even the empty field needs to be concatenated.
My already tried out ideas –
a. Wrote a java service to parse Idata and values, but the empty values were not part of the pipeline.
b. Tried with FlatFile schema, even this is ignoring the empty fields.
None of the above was successful.
Could you throw in your ideas.
