---------------------------------
Summary: Rework partitioned state storage
Key: FLINK-2324
URL: https://issues.apache.org/jira/browse/FLINK-2324
Project: Flink
Issue Type: Improvement
Reporter: Gyula Fora
Assignee: Gyula Fora
Partitioned states are currently stored per-key in statehandles. This is
alright for in-memory storage but is very inefficient for HDFS.
The logic behind the current mechanism is that this approach provides a way to
repartition a state without fetching the data from the external storage and
only manipulating handles.
We should come up with a solution that can achieve both.
