Digital twin change feed

A system of an environment, comprising:

• one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to:
• receive a change to a graph, the graph comprising a plurality of nodes and a plurality of edges between the plurality of nodes, the plurality of nodes representing entities of the environment and the plurality of edges representing relationships between the entities of the environment;
• generate an event recording the change to the graph;
• and
• post the event to a topic to cause the event to be delivered to a system or component subscribed to the topic;
• wherein a plurality of events are posted to the topic to provide a feed of changes to the graph made a plurality of different times.

A method, comprising:

• receiving, by one or more processing circuits, a change to a graph, the graph comprising a plurality of nodes and a plurality of edges between the plurality of nodes, the plurality of nodes representing entities of an environment and the plurality of edges representing relationships between the entities of the environment;
• generating, by the one or more processing circuits, an event recording the change to the graph;
• and
• posting, by the one or more processing circuits, the event to a topic to cause the event to be delivered to a system or component subscribed to the topic;
• wherein a plurality of events are posted to the topic to provide a feed of changes to the graph made a plurality of different times.

One or more storage media having instructions thereon, that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving a change to a graph, the graph comprising a plurality of nodes and a plurality of edges between the plurality of nodes, the plurality of nodes representing entities of an environment and the plurality of edges representing relationships between the entities of the environment;
• generating an event recording the change to the graph;
• and
• posting the event to a topic to cause the event to be delivered to a system or component subscribed to the topic;
• wherein a plurality of events are posted to the topic to provide a feed of changes to the graph made a plurality of different times.
