Gabor Horvath updated FLINK-3599:
---------------------------------
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].
