Abstract: Embodiments of the present disclosure relate to methods and apparatuses for group message processing, system, and computer medium. In least one of the embodiments of the present disclosure, for a supersized group, i.e., a group with a number of members exceeding a predetermined number, a server creates a group inbox corresponding to the supersized group. After obtaining messages for the supersized group, instead of directly sending message events to the personal inboxes for respective members of the supersized group in a “write diffusion” mode, the message events are stored in a group inbox of the supersized group. So that when a user activates a client, the message events are obtained from the group inbox by the client, which achieves a “read diffusion” mode. As compared with the “write diffusion” mode, the “read diffusion” mode can reduce the resource consumption by the server, and improve the system stability.
