Abstract

The invention provides a method and a system for sending messages. The method comprises the following steps of judging whether the state of each message sending progress in the N message sending progresses is a valid state or not; determining the states of K message sending progresses to be valid states from the N message sending progresses on the basis of judgment, wherein K is integer which is greater than 1 but less than or equal to N; determining one message sending progress from the K message sending progresses to be a main message sending progress; starting a message scheduler in a message task server where the main message sending progress is positioned by the main message sending progress; acquiring at least one message to be sent without progress attribution from a message queue of a database by the message scheduler; allocating one message sending progress for each message to be sent in at least one message to be sent without progress attribution; and sending at least one message to be sent without progress attribution by K message sending progresses.

Description

technical field [0001] The present application relates to the field of computer distributed systems, in particular to a method and system for sending messages in a distributed system. Background technique [0002] With the continuous development of Taobao Mall, there are more and more merchants and more and more users. In order to better serve users or merchants, it is necessary to send a lot of messages to merchants or users, such as sending Wangwang messages, Letters, short messages and emails in Taobao station. [0003] In general, the above information is sent to users or merchants through the distributed system, and in order to send messages efficiently, the distributed system uses a concurrent method to send messages. [0004] Please refer below figure 1 , which is a schematic structural diagram of distributed system message distribution in the embodiment of the present application. The message sending system provides an external interface to receive messages from t...
