Abstract

Techniques to manage large numbers of subscribers to real-time events are described. Embodiments may filter subscribers dynamically into buckets where publications are distributed only to subscribers in the same bucket as the publisher. Buckets may be dynamically created and removed to lower or raise the publication rate for subscribers to an acceptable level. Embodiments may use a two-level bucketing algorithm for filtering that is memory and CPU efficient, and scales with large numbers of subscriptions. The techniques may also reduce the context loss for a subscriber when a new bucket has to be created and subscribers distributed between buckets. Embodiments may be scaled out to multiple servers, to accommodate very large numbers of subscribers and publications. Other embodiments are described and claimed.
