Fundamental assumptions are that data will arrive in temporal order, at some discrete frequency and periodicity. Data should not be sent in batches with data records potentially out-of-temporal-order. GeoEvent Server can receive batches of data, but the batch is assumed to be a collection of individual observations from discrete sensors, not a collection of observations from a single sensor.</P><P>You might want to look into using SDK samples available on the <A href="http://links.esri.com/geoevent-gallery" target="_self">GeoEvent Server Gallery</A> to supplement your solution.

In my understanding,&nbsp;GeoEvent is an asynchronous product to increase throughput.&nbsp;</P> Wed, 13 Oct 2021 15:55:21 GMT https://community.esri.com/t5/arcgis-geoevent-server-questions/can-geoevent-support-sychronous-messaging-to-avoid/m-p/1107131#M3639 WilliamYip 2021-10-13T15:55:21Z https://community.esri.com/t5/arcgis-geoevent-server-questions/can-geoevent-support-sychronous-messaging-to-avoid/m-p/1107359#M3642 <P>Hello William --</P><P>The inbound connectors you configure assume that they will receive the latest avilable data from a sensor network in real-time or near-real-time.
