Trigger

yaml

type: "io.kestra.plugin.debezium.mongodb.Trigger"

Wait for change data capture event on MongoDB server and create new execution.

If you would like to consume each message from change data capture in real-time and create one execution per message, you can use the io.kestra.plugin.debezium.mongodb.RealtimeTrigger instead.

Examples

WHEN_NEEDED: The connector runs a snapshot upon startup whenever it deems it necessary. That is, when no offsets are available, or when a previously recorded offset specifies a binlog location or GTID that is not available in the server.
