In this talk I will present a recovery architecture for in-memory data management systems. Recovery in such systems boils down to solving two problems: retrieving and installing the last committed image of the crashed database on an available server and replaying the updates missing from the image. We improve recovery time with two simple techniques: Asynchronous Remote Checkpointing reduces the time to retrieve and install a database image. On-demand Recovery removes the need to replay all missing updates before new transactions can be accepted. In addition to presenting the two techniques, I will comment on their implementation and performance in the context of Sprint, a middleware-based in-memory data management system we have developed. A apresentação será em português.
