Abstract
The described technology is generally directed towards consistently replicating and reconstructing a data stream made up of a dynamic set of (ordered) segments into a different location (e.g., cluster) from the one in which the stream was created. The technology facilitates consistently and generally continuously and replicating a stream of events ingested in a source cluster to a target cluster for consumption (reading). As stream data segments are replicated to a target cluster by a replicator which is not guaranteed to keep the replicated data consistent, a target controller reconstructs the replicated data stream up to a stream cut point at which the replicated data has been sufficiently replicated so as to be consistent. Reading of the replicated data stream is limited to a view up to the stream cut point; as more data is replicated, additional data up to a later stream cut point becomes available for reading.
