How to unpack/de-merge a file in NiFi that was previously merged in "Binary Concatenation" format

Hi All,

I'm trying to unpack/de-merge merged text files that were merged earlier using the "Binary Concatenation" format; in the UnpackContent processor's "Packaging Format" property, there is no "Binary Concatenation" format available; by the way we're on NiFi 1.0.1;

Is there a workaround ?

Thanks.

Since binary concatenation is just writing chucks of raw bytes one after another, there is no real format that can be understood to undo it. There would be no way for another processor to read those bytes and know where it was merged together.

If you use a demarcator when merging, then you can use that to unmerge by using SplitContent or SplitText.

@Bryan Bende thank you, I'm trying with SplitContent, initial results are encouraging.
