Changes
Added
reload_inflightmethod to the serializer module which reads from disk and publishes packets back ontoEventLoopand deletes the file.Why?
Graceful shutdown requires graceful recovery on restart, which means we need to load publishes back from file.
Trials Performed
Spinned up docker instance and used qa-scripts like
qa-scripts/persistence.shto test out the functionality.
