Abstract

A publisher, a subscriber or a message broker sets a messaging engine in the message broker to send or forward one or more messages to subscriber(s) after receiving a specific number of messages on specific topic(s) within a specific time interval. A plurality of publishers publishes messages on the specific topic(s). A messaging engine receives the published messages. If the number of the published messages on the specific topic(s) becomes the specific number of messages within a specific time interval, the messaging engine sends or forwards a single or plural message(s) on the specific topic to the subscriber(s). Otherwise, the messaging engine does not send or forward any message on the specific topic to the subscriber(s).
