RealtimeTrigger RealtimeTrigger

yaml
type: "io.kestra.plugin.debezium.mongodb.RealtimeTrigger"

Consume a message in real-time from a MongoDB database via change data capture and create one execution per row.

If you would like to consume multiple messages processed within a given time frame and process them in batch, you can use the io.kestra.plugin.debezium.mongodb.Trigger instead.

    • ON_EACH_BATCH
    • ON_STOP

How to commit the offsets to the KV Store.

Possible values are:

  • ON_EACH_BATCH: after each batch of records consumed by this trigger, the offsets will be stored in the KV Store. This avoids any duplicated records being consumed but can be costly if many events are produced.
  • ON_STOP: when this trigger is stopped or killed, the offsets will be stored in the KV Store. This avoid any un-necessary writes to the KV Store, but if the trigger is not stopped gracefully, the KV Store value may not be updated leading to duplicated records consumption.
