Summary: GSoC: Code Generation in Serializers
Key: FLINK-3599
URL: https://issues.apache.org/jira/browse/FLINK-3599
Project: Flink
Issue Type: Improvement
Components: Type Serialization System
Reporter: Márton Balassi
Assignee: Gabor Horvath
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].
