The Teradata Listener Ingest micro-service 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.
The Listener micro-services platform manages the automatic scaling of micro-services based on a pre-configured resource usage 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.
|max_replicas||Maximum instances Ingest-services can scale up to.|
|min_replicas||Minimum instances Ingest-services can scale down to.|
|current_replicas||Number of currently running instances of Ingest-services.|
|last_scale_time||Timestamp of when the ingest-service was scaled up or down.|
|replicas_available||Total number of replicas available (calculated based on resources available).|
