External Stream

You can also create External Streams in Timeplus to query data in the external systems without loading the data into Timeplus. The main benefit for doing so is to keep a single source of truth in the external systems (e.g. Apache Kafka), without duplicating them. In many cases, this can also achieve even lower latency to process Kafka or Pulsar data, because the data is read directly by Timeplus core engine, without other components, such as Redpanda Connect or Airbyte.
