A Vertica notifier is a push-based mechanism for sending messages from Vertica to endpoints like Apache Kafka or syslog.

A Vertica notifier is a push-based mechanism for sending messages from Vertica to endpoints like Apache Kafka or syslog. For example, you can configure a long-running script to send notifications at various stages and then at the completion of a task.

To use a notifier:

  1. Create a syslog or Kafka notifier.

  2. Send a notification to the NOTIFIER endpoint with any of the following:

    • NOTIFY: Manually sends a message to the NOTIFIER endpoint.

    • SET_DATA_COLLECTOR_NOTIFY_POLICY: Creates a notification policy, which automatically sends a message to the NOTIFIER endpoint when a specified event occurs.
