Smart Factory Datalake Workshop

Brining Context to the data

In order to make the data useful we need to bring some more context to the data.

The OPC UA Connector includes a contextualizer - let’s have a look in the code what it’s doing.

Open the Lambda service from AWS Console:

Open the OPCUA-Connector... function.

Then lets look into the python script called contextualize.py

So this portion is a stateful function which adds the current product id to all events that are processed - in this way you don’t need to have a complex calculation later on to add this context.

For this workshop you don’t need to modify anything here but if you have different data it’s a good pattern do add more context to the incoming events.
