## Abstract

A data processing method providing message synchronization, the method comprising: maintaining, by a server computer implementing a communications service, a stream of events comprising a plurality of members, the stream of events representing a thread of communication between the plurality of members, wherein each event in the stream comprises a sequence number; receiving, by the server, a request to synchronize a local state of a client computer, wherein the client computer is associated with a member of the plurality of members; sending a plurality of new events to the client computer using sequence numbers of the stream of events, wherein the client computer represents the thread of communication as conversations; receiving, by the server, a conversation object comprising a temporary identifier from the client computer; assigning, by the server, a globally unique identifier to the conversation object; notifying, by the server, the plurality of members of the conversation object.

## Claims

### Claim 1

A data processing method providing message synchronization, the method comprising:
maintaining, by a server computer implementing a communications service, a stream of events comprising a plurality of members, the stream of events representing a thread of communication between the plurality of members, wherein each event in the stream comprises a sequence number;
receiving, by the server computer, a request to synchronize a local state of a client computer, wherein the client computer is associated with a member of the plurality of members;
sending, by the server computer, a plurality of new events to the client computer using sequence numbers of the stream of events, wherein the client computer represents the thread of communication as conversations;
receiving, by the server computer, a conversation object comprising a temporary identifier from the client computer;
assigning, by the server computer, a globally unique identifier to the conversation object;
notifying, by the server computer, the plurality of members of the conversation object.
