The Activity Feed node establishes a connection with the Security Manager application through an Application Programming Interface (API). The API has a limit of processing 500 messages per second. This limit is far beyond what you would normally expect. However, you can easily reach that limit if you use many connections that fetch the same data at once.

Therefore, use as few Activity Feed nodes in the workflow as possible.

For sharing the data output from the Activity Feed node across multiple flows without having to overload the number of connections on the Activity Feed API, use the link in and link out nodes.

Avoid using multiple Activity Feed nodes in the flows as this could result in a degraded performance. Use the link in / link out nodes for sharing the activity feed data across multiple flows.
