Is there a way to read arbitrary valid batch JSON input
looks like the standard Apache NiFi readers/writers can only parse JSON input based on Avro schema.
Avro schema is limiting for JSON, e.g. it does not allow valid JSON properties starting with digits.
JoltTransformJSON processor can help here (it doesn't impose Avro limitations to how the input JSON may look like), but it seems that this processor does not support batch FlowFiles. It is also not based on the readers and writers (maybe because of that).
Is there a way to read arbitrary valid batch JSON input, e.g. in multi-line form
and transform it to other JSON structure, e.g. defined by JSON schema, and e.g. using JSON Patch transformation, without writing my own processor?
Note we are using Apache NiFi 1.7.1
