  • Patent number: 10860457
    Abstract: Methods, systems, and computer-readable media for globally ordered event stream logging are disclosed. A first host of a plurality of hosts generates an additional chain of a stream comprising a plurality of chains and representing a globally ordered sequence of events. The first host sends information describing the additional chain to a second host. The second host receives a request to store a data object representing an event. The request is associated with a stream identifier of the stream. The second host stores, in the additional chain, the data object, a timestamp associated with the data object, and an identifier of the second host. The data object in the additional chain is associated with a position in the globally ordered sequence across the plurality of chains.
