------------------------------
Assignee: Yan Fang
> Provide a tool to debug state stores
> ------------------------------------
>
> Key: SAMZA-598
> URL: https://issues.apache.org/jira/browse/SAMZA-598
> Project: Samza
> Issue Type: Bug
> Components: kv
> Affects Versions: 0.9.0
> Reporter: Chris Riccomini
> Assignee: Yan Fang
> Fix For: 0.10.0
>
>
> There is currently no easy way to debug a Samza job when there are problems
> with the state store data. It would be nice to provide a tool that will:
> # Connect to a local KV state store, and dump its content.
> # Consume a changelog to and materialize a state store locally.
> Optionally, it would be nice to allow users to fetch values for a give key
> via a REPL. This is a little tricky, though, since the key might be
> serialized in Protobu, Avro, etc.
> Between 1-2, users will be able to inspect local stores of jobs that are
> running (1), and create a local copy of a state store for jobs that have lost
> their local state already (2).
