             Summary: Checkpointing API for State Stores
                 Key: KAFKA-9986
                 URL: https://issues.apache.org/jira/browse/KAFKA-9986
             Project: Kafka
          Issue Type: New Feature
            Reporter: Nikolay Izhikov


The parent ticket is KAFKA-3184.

The goal of this ticket is to provide a general checkpointing API for state stores in Streams (not only for in-memory but also for persistent stores), where the checkpoint location can be either local disks or remote storage. 

Design scope is primarily on:

  # the API design for both checkpointing as well as loading checkpoints into the local state stores
  # the mechanism of the checkpointing, e.g. whether it should be async? whether it should be executed on separate threads? etc.
