GSoC: Code Generation in Serializers

    XMLWordPrintableJSON

    Details

      Description

      The current implementation of the serializers can be a
      performance bottleneck in some scenarios. These performance problems were
      also reported on the mailing list recently [1].

      E.g. the PojoSerializer uses reflection for accessing the fields, which is slow [2].

      For the complete proposal see [3].
