markap14 opened a new pull request #3801: NIFI-6760: When writing/reading the length of a DataFrame, do so usin… URL: https://github.com/apache/nifi/pull/3801 …g a 4-byte integer instead of a 2-byte short. When using uncompressed data, we know that the length of the DataFrame will be no more than 64 KB so a 2-byte short is sufficient. However, if data is compresed, there's a chance that the compressed form of the data will be larger than the uncompressed form (for example, with random binary data or with encrypted data). In this situation, we can end up overflowing the 2-byte short, which causes the length that is written to be wrong. Using a 4-byte integer avoids this situation.
