Hello all, I am trying to work out an issue with little success.
I need to ingest files generated by some application. I can only ingest these files when a specific set exists. For example: file_123_456_ab.ex1 file_123_456_cd.ex1 file_123_456_ef.ex1 file_123_456_gh.ex1 file_123_456.ex2 Only when a set like that exists should I pick them up into the Flow. The parts I am looking for to "group" would "ab.ex1", "cd.ex1", "ef.ex1", "gh.ex1", ".ex2". I tried to do this with some expression, but couldn't work it out. What would be the best way to achieve this? Many thanks!
