Abstract: Subscriptions for object updates to be transmitted to a client device may be dynamically managed based on the occurrence of one or more trigger events at the client device, which causes the client device to transmit subscription modification requests to a computing platform configured to dynamically maintain object subscription lists for each of one or more client devices based at least in part on subscription modification requests received from each of the one or more client devices, to determine whether subscribed objects for a particular client device are current at the client device, and to transmit updates of subscribed objects in real-time upon determining that the particular client device does not comprise current object data.

Abstract: Various embodiments are directed to systems and methods for automatically distributing loads among computing devices involved in message delivery within a group-based communication platform. Embodiments utilize a status checker to monitor the relative health and/or utilization of various channel servers each servicing a group-based communication channel for communication among a particular group of client devices. Upon detecting that one or more of the channel servers exhibit failing health characteristics, the status checker may automatically reallocate the messaging load performed by the failing channel server to other servers, thereby redefining the group-based communication channel associated with a particular group to encompass the newly assigned channel server and minimizing the impact of the failed channel server on message distribution within the group-based communication channel.

Abstract: The Messaging Search and Management Apparatuses, Methods and Systems (“MSM”) transforms message, ranking request inputs via MSM components into work graphs, ML structure input data, ML structure, ranking response outputs. A work graph generation request that includes group level access control data may be obtained. A set of metadata access control carrying messages, a set of users, a set of channels, and a set of topics with access control data corresponding to the group level access control data may be determined. A user priority score for each of the other users, a channel priority score for each of the channels, and a topic priority score for each of the topics, from the perspective of each user, may be calculated. A work graph data structure may be generated that includes, for each user, data regarding the calculated user priority scores, channel priority scores, and topic priority scores.

Abstract: Updating object subscriptions based on trigger events is described. An indication of a trigger event, associated with an object, can be received from a client of a user. The object can be associated with current object data that is stored in a storage area of a subscription management system. The storage area can maintain the current object data for at least the object and a subscription list for client(s), wherein the subscription list for each of the client(s) comprises object identifiers corresponding to subscribed objects for each of the client(s). Based at least partly on receiving the indication of the trigger event and determining that the trigger event is associated with a modification to a subscription, the subscription list can be updated to generate an updated subscription list for the client and current object data for the subscribed objects identified within the updated subscription list can be provided thereto.

Abstract: Method, apparatus and computer program product for querying a group-based communication platform are described herein. For example, the apparatus comprises at least one processor and at least one non-transitory memory including program code. The at least one non-transitory memory and the program code are configured to, with the at least one processor, cause the apparatus to at least store a plurality of electronic messages to a message corpus; receive a search query associated with the message corpus, wherein the search query comprises reaction metadata criteria; and apply the search query to the message corpus to generate a reaction search results set.
