[jira] [Created] (NIFI-6088) JSON Record Readers infer all fractional numbers as floats, leading to truncation

             Summary: JSON Record Readers infer all fractional numbers as floats, leading to truncation
                 Key: NIFI-6088
                 URL: https://issues.apache.org/jira/browse/NIFI-6088
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Matt Burgess


When using the "Infer Schema" strategy on JSON Record Readers (JsonPathReader, JsonTreeReader, e.g.), all fractional numbers are inferred as floats, meaning there can be some truncation if the value can only truly fit in a double. The inference code is meant to fit the field to the widest of its type, so it should infer fractional fields as doubles rather than floats.
