This article is about how to carry out the structural analysis of the SAP Data Intelligence Graph json source code, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Take the example Graph com.sap.demo.http.server of the SAP Data Intelligence standard as an example, save its json code locally, and use the json editor to view:

There are eight line connections between the operator, corresponding to the eight elements in the connections array in the json file:

Each element contains two objects, source and target. The following figure is an example:

The src object represents the get port in the figure:

Target stands for message named request:

Id blankjavascriptoperator2 can be seen on the configuration page of GET handler:

The six nodes in the figure, that is, the six Operator, are the six sub-objects in the Processes object in json:

Its route path is / objects/:id, with three output:

Three outport:

First, take a look at the jsOperator labeled object store:

According to three different types of HTTP requests, get,post and delete, read, insert and delete data from object store:

After understanding this idea, it is easy to understand http get handler: extract parameters from the http request, construct a message and send it to outport.

As you can see from the source code of 31multiplexer, it does not contain any configuration itself:

The above is how to analyze the structure of the SAP Data Intelligence Graph json source code. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
