Abstract: Systems and methods are provided for synchronizing messages. The systems and methods include operations for: receiving, from a server by a client device, a set of synchronization data representing changes since a previous time the client device synchronized with the server; comparing, by the client device, the set of synchronization data to a local state of the synchronization data; identifying a difference between the set of synchronization data and the local state of the synchronization data; and transmitting, to the server by the client device, a request for content corresponding to the difference between the set of synchronization data and the local state of the synchronization data.

Abstract: Method of dynamically assigning storage locations starts with the processor updating first user's home location data. Processor selects communication session between first user and second user and determines second user's home location data. Processor determines a session location data that indicates current storage location that stores data of communication session received from first and second client devices. Processor identifies available data storage locations based on first user and second user's home location data and determines whether to update the session location data based on an average of a distance over network fiber using the first user and second user's home locations, current storage location, and available storage locations. In response to determining to update the session location data, processor updates session location data to indicate one of the available storage locations, and causes transfer of data of communication session to one of the available storage locations.

Abstract: Systems and methods are provided for synchronizing messages. The systems and methods include operations for: accessing, by a server, a plurality of messages of a communication session implemented by a messaging application on a user device; generating, by the server, a summary of the communication session based on the plurality of messages; transmitting, by the server, data associated with the summary to the user device; and causing the user device to display of a summary view of the communication session based on the data received by the user device from the server.

Abstract: Method of dynamically assigning storage locations starts with the processor receiving a signal from a first client device associated with a first user. Processor stores a current location of the first client device in a historical database and determines whether a home location data associated with the first user matches the current location. In response to determining that the home location data associated with the first user does not match the current location, processor determines whether the first user has been associated with the current location at a greater frequency than the home location data based on the historical database. In response to determining that the first user has been associated with the current location at a greater frequency, processor updates the home location data associated with the first user to the current location. Other embodiments are described.

Abstract: Methods, systems, and computer readable medium are provided for receiving an event message in a plurality of event messages, the event message comprising a sequence number and associated data, identifying the event message as an out-of-order event message based on the sequence number, assigning a priority level to the out-of-order event message based on a plurality of priority rules, and placing the out-of-order event message in a primary queue of messages based on the priority level assigned to the event message.

Abstract: Systems and methods are provided for data synchronization for client application generated data. Content may be generated by a client application executed by a creator client device and sent to a server system that may distribute the content to one or more additional client devices of recipients of the content. The server system can push content to the recipient client devices without receiving a request for the content from the recipient client devices. The content generated by the creator client device may be stored by each of the creator client device, by the server system, and by the one or more recipient client devices. The server system may also generate version data related to respective versions of content that may be consumed by a client application. The version data may be used by client devices to determine versions of content that may be missing from the client devices.

Abstract: Systems and methods are provided for synchronizing data. The systems and methods include operations for: storing a synchronization entry for a messaging application feature, the synchronization entry comprising a last update timestamp associated with a first update to content of the messaging application feature received from a first source; receiving a second update to the content of the messaging application feature from the first source; determining that the second update was received within a write window of the last update timestamp; in response to determining that the second update was received within the write window of the last update timestamp, preventing updating the last update timestamp; and sending the first update and the second update to a client device in response to receiving a synchronization request from the client device based on the last update timestamp.

Abstract: Systems and methods are provided for transmitting events. The systems and methods include operations for: receiving data indicating a level of user engagement with a messaging application for a given user; determining that the level of user engagement is below a specified threshold; prioritizing a plurality of events, associated with the messaging application, for transmission to a client device of the given user in response to determining that the level of user engagement is below the specified threshold; and transmitting a first event of the plurality of events to the client device based on prioritizing the plurality of events.
