-------------------------------------
Summary: Make incremental checkpoints externalizable
Key: FLINK-6545
URL: https://issues.apache.org/jira/browse/FLINK-6545
Project: Flink
Issue Type: Sub-task
Components: State Backends, Checkpointing
Affects Versions: 1.3.0
Reporter: Stefan Richter
Priority: Blocker
Fix For: 1.3.0
Incremental checkpoints are currently not externalizible. The missing piece is
familiarizing the {{SavepointSerializer}}(s) with the new state handles classes
that we added for incremental checkpointing. Currently, some of those (e.g.
{{org.apache.flink.contrib.streaming.state.RocksDBIncrementalKeyedStateHandle}})
currently live in the contrib.rocksdb package and need to be migrated. We can
also push them to a different abstraction level, i.e.
{{IncrementalKeyedStateHandle}} with some private data, referenced existing
shared data (from previous checkpoints), and (presumably) newly created shared
data (first created by the current checkpoint).
