DATA REPLICATION FRAMEWORK

摘要

Generally described, the present disclosure is directed to an eventually consistent replicated data store that uses, for its underlying storage, a computer software library that provides a high-performance embedded database for data. The replicated data store employs a plurality of hosts interconnected to one another, allowing for writes to any host and full awareness of membership across all hosts. With the data replication framework disclosed herein, various modes are allowed to be built up on top of the core system.

主权项

1. A method of communicating between hosts members while preventing permanent network partitions, the method comprising:
accepting a session from a peer member; querying a member store for an availability state associated with the peer member; synchronizing member store information with the peer member if the availability state of the peer member indicates the peer member as available; and ignoring member store information from the peer member if the availability state of the peer member indicates the peer member as permanently unavailable; wherein the method is performed on a computing device comprising a processor and memory.
