To provide iOS app builders an alternative caching solution to Apple’s Core Data framework, LinkedIn is offering its Rocket Data caching library via open source.
Available under an Apache license, Rocket Data is based on a nonblocking immutable model management system with a persistent synchronization layer. LinkedIn developed Rocket Data while rewriting its mobile app, when it wanted a caching system that would present content to users while still loading data from the network. The company wasn’t satisfied with Core Data as a solution, believing it lacked scalability and had several other issues.
