> Improve exception handling for state stores
> -------------------------------------------
>
> Key: KAFKA-5314
> URL: https://issues.apache.org/jira/browse/KAFKA-5314
> Project: Kafka
> Issue Type: Sub-task
> Components: streams
> Affects Versions: 0.11.0.0
> Reporter: Eno Thereska
> Assignee: Eno Thereska
> Fix For: 0.11.0.0
>
>
> RocksDbStore.java throws a mix of exceptions like StreamsException and
> ProcessorStateException. That needs to be made consistent.
> Also the exceptions thrown are not documented in the KeyValueStore interface.
> All the stores (RocksDb, InMemory) need to have consistent exception handling.
> Today a store error is fatal and halts the stream thread that is processing
> the exceptions. We could explore alternatives, like haling part of the
> topology that passes through that faulty store, i.e., failing tasks, not the
> entire thread.
