-------------------------------------
Summary: 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
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).
