> Introduce TimerState in keyed state backend
> -------------------------------------------
>
> Key: FLINK-9486
> URL: https://issues.apache.org/jira/browse/FLINK-9486
> Project: Flink
> Issue Type: Sub-task
> Components: State Backends, Checkpointing
> Reporter: Stefan Richter
> Assignee: Stefan Richter
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0
>
>
> This is the first implementation subtask.
> Goal of this PR is to introduce a timer state that is registered with the
> keyed state backend, similar to other forms of keyed state.
> For the {{HeapKeyedStateBackend}}, this state lives on the same level as the
> {{StateTable}} that hold other forms of keyed state, and the implementation
> is basically backed by {{InternalTimerHeap}}.
> For {{RocksDBKeyedStateBackend}}, in this first step, we also introduce this
> state, outside of RocksDB and based upon {{InternalTimerHeap}}. This is an
> intermediate state, and we will later also implement the alternative to store
> the timers inside a column families in RocksDB. However, by taking this step,
> we could also still offer the option to have RocksDB state with heap-based
> timers.
