EN | ES

Description

The Onesait origin stage is used to connect to the Digital Broker of the Onesait platform once it has a IoT device configured and accesible.

It supports connecting to different origins in separated pipelines.

To add it to the pipeline, search for Onesait in the stages palette like so.

Drag and drop to the panel.

Once imported, it can be configured to achieve different beheaviours depending on the case.

This tab has general information and an option to show the event generator point on the stage.

Checking the "Produce Events" option the stage shows another point to make usage of the events.

The events are triggered on

This tab shows a form to fill with the Digital Broker information of the Onesait platform.

Where is the information?

All the information needed is available on the platform in the IoT section.

This tab shows the query and some more configuration of the stage.

Query: The query to send to the Digital Broker
Query type: Native or SQL
Batch number: The items to retreive on every batch. Note: Only works when performing iteration. See the next setcion.
Starting offset: Set if need to start from any specific point on the query.
Delay: Milliseconds to wait between queries.
Stop on complete: Stops the pipeline if it reaches the last item on the ontology.
Delay On No Results (ms): The time interval in milliseconds between queries when no data is received.

In order to make batches on the queries it is needed on the query sintax to include the variables batch and offset.

Eg.

Using just one variable will produce an error.

This sintax will make interations on the ontology and finish once no more data is fetched if the option Stop on complete is checked.

If it is not checked, it will make calls repeteadly until the user stops the pipeline.
