Abstract

Disclosed is a technology for publishing subscriptions in a publish-subscribe system in accordance with subscription groups. The technology may include (i) determining a consumption characteristic by which each of multiple subscribers in a publish-subscribe system consumes a subscription published by a publisher; (ii) identifying the subscribers whose consumption characteristics satisfy a specified similarity criterion; (iii) defining multiple subscription groups, each of which includes subscriptions of those of the subscribers whose consumption characteristics satisfy the specified similarity criterion; (iv) storing the subscriptions in multiple logical partitions of a storage system where each of the logical partitions contains a separate non-overlapping subset of the subscriptions; and (v) transmitting the subscriptions to the subscribers in accordance with the subscription groups.
