-----------------------------------
Summary: Disable reference tracking in Kryo fallback serializer
Key: FLINK-3267
URL: https://issues.apache.org/jira/browse/FLINK-3267
Project: Flink
Issue Type: Bug
Components: Local Runtime
Affects Versions: 0.10.1
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.0.0
Kryo runs extra logic to track and resolve repeated references to the same
object (similar as JavaSerialization)
We should disable reference tracking
- reference tracking is costly
- it is virtually always unnecessary in the datatypes used in Flink
- most importantly, it is inconsistent with Flink's own serialization (which
does not do reference tracking)
- It may have problems if elements are read in a different order than they
are written.
