Rendezvous: Where Serverless Functions Find Consistency

Function-as-a-Service has been notoriously difficult to compose and integrate, leaving developers to resort to third-party datastores and queues as means to share state between functions. Applying this architecture on a geo-replicated setting may produce inconsistent application states due to replication delays and weak consistency guarantees, thereby resulting in inconsistent function outputs and ultimately a bad end-user experience. Rendezvous is a framework that automatically ensures consistency of data in serverless applications using datastores, and guarantees that no stale values are read.
