Abstract: The disclosed embodiments provide a system for improving use of a social network. During operation, the system obtains job histories for members of the social network. Next, the system aggregates a set of job transitions in the job histories to obtain a set of job transition trends associated with the members. The system then matches a job transition trend in the set of job transition trends to member features for a member of the social network. Finally, the system outputs the job transition trend as a recommendation for advancing a career of the member.

Abstract: The disclosed embodiments provide a system for processing data. During operation, the system obtains a set of derived data sets for use by a set of clients. For each derived data set in the set of derived data sets, the system produces a default version of the derived data set from multiple versions of the derived data set. The system then outputs the default version and the multiple versions for retrieval by the set of clients through an online data store, an offline data store, and a nearline data store.
