---------------------------------------
Summary: Duplicate TypeSerializer when writing RocksDB Snapshot
Key: FLINK-5154
URL: https://issues.apache.org/jira/browse/FLINK-5154
Project: Flink
Issue Type: Bug
Components: Streaming
Reporter: Aljoscha Krettek
Assignee: Stefan Richter
Priority: Blocker
Fix For: 1.2.0, 1.1.4
Some {{TypeSerializers}} are not thread safe (for example {{KryoSerializer}})
we have to {{duplicate()}} them when using concurrently, as happens when
performing a RocksDB snapshot.
