currently i am facing an issue splitting my batches fetched from filelogreader by “filename”
My assumption was that creating header in filelogreader receiver results in that, unforuntately i struggle with it.

Does anyone faced same issue in the past?

    header:
      # Pattern machtes only values of "attributes" in event
      pattern: '"resource":{.+?}'
      metadata_operators:
        - type: regex_parser
          #regex: '"filename":"(?P<filename>.+?)"'
          regex: '(?P<filename>.*)'

batch/lta:
    send_batch_size: 1000
    timeout: 10s
    metadata_keys:
      - filename
