Load on CAP API

[sujitsingh5191]

We need to check how many users can access an API built by a CAP application.

Or how many calls to an API we can make at a time for CAP APIs.

This is mainly to balance the load on the service. Is there any way SAP provides us to check that?

I would suggest that you run a load test against one instance with different memory assignments to get a feeling how much traffic you app can handle. Then start testing the scale out scenario with additional instances.

Sujit, there is a lot of good stuff on the cap website (https://cap.cloud.sap/) as to how to improved load handling.

The three things I have used successfully are:

1. Probably the most important one is to adjust the default connection pool information https://cap.cloud.sap/docs/node.js/databases#pool

2. Memory utilization, memory parameter in mta module (https://help.sap.com/viewer/4505d0bdaf4948449b7f7379d24d0f0d/2.0.05/en-US/4050fee4c469498ebc31b10f2ae15ff2.html)

3. Number of instances: vial instances parameter.

You can then use the standard Kibana logging to track the impact on memory, database etc.
