Atlas Stream Processing (ASP) currently recompiles a stream processing pipeline every time a stream processor is stopped and restarted from a checkpoint. But this is error-prone. The query plan could change after a restart due to any changes in the pipeline optimization logic. This would result in stream processor not being able to restore its state from its checkpoint.
To avoid this, we want to serialize an optimized query plan, write it to a stream processor's checkpoint and reinitialize the pipeline using the plan stored in the checkpoint when restarting a stream processor.
