Project: Flink
Issue Type: Bug
Components: API / Type Serialization System, Benchmarks
Affects Versions: 1.10.0

http://codespeed.dak8s.net:8000/timeline/?ben=serializerRow&env=2
http://codespeed.dak8s.net:8000/timeline/?ben=serializerPojo&env=2
it coincides with the performance improvement for heavy strings
http://codespeed.dak8s.net:8000/timeline/?ben=serializerHeavyString&env=2
it might be caused by some accidental change in the benchmarking code (changing
parallelism in one benchmarks is carried on to the next one?) or in the code
itself.
