Nick Nezis commented on FLINK-3154:
-----------------------------------
If we are dropping compatibility, that does make sense. Although the solution
you provided was nice because it did provide an upgrade path from the older
format to the newer format. But either way, I feel that this upgrade should be
prioritized now that we are targeting 2.x Flink.
> Update Kryo version from 2.24.0 to latest Kryo LTS version

> Key: FLINK-3154
> URL: https://issues.apache.org/jira/browse/FLINK-3154
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Affects Versions: 1.0.0
> Reporter: Maximilian Michels
> Priority: Not a Priority
> Labels: pull-request-available

> Flink's Kryo version is outdated and could be updated to a newer version,
> e.g. kryo-3.0.3.
> From ML: we cannot bumping the Kryo version easily - the serialization format
> changed (that's why they have a new major version), which would render all
> Flink savepoints and checkpoints incompatible.
