-------------------------------------

             Summary: Efficiently handle read-only buffers in DataInputDeserializer
                 Key: FLINK-8585
                 URL: https://issues.apache.org/jira/browse/FLINK-8585
             Project: Flink
          Issue Type: Improvement
          Components: Network
    Affects Versions: 1.5.0
            Reporter: Piotr Nowojski


Currently read-only and non array based buffers are handled inefficiently by DataInputSerializer, since they require additional data copy to an internal array. This could be replaced by using a ByteBuffer as a data source instead of byte[].
