Teradata Listener Ingest is a micro-service that receives and pushes data into the Listener data pipeline to stream to a target. Ingest is the only way to send data to a Listener instance.
Increasing the number of Ingest instances increases the rate that data loads into Listener, but not the rate that Listener processes the data.
Listener's micro-services platform manages the automatic scaling of micro-services based on a pre-configured resource utilization profile. Ingest is the only scalable micro-service, which is configurable by Listener administrators.
The auto-scaling paradigm for each supported micro-service is configured by an administrator who sets the maximum number of micro-service replicas using either the API or UI. Administrators cannot change the minimum setting for Ingest instances.
