EventOccurredFilter

in prefect

The

EventOccurredFilter

in Prefect is used within the context of event-driven automation. It allows you to filter events based on specific criteria such as the resource type or related resources. This is particularly useful when you want to trigger actions based on specific event occurrences. Here's a brief overview of how you might use it: 1. Define Match Filters: You can specify filters to match events based on their primary resource or related resources. For example, you might filter events where the primary resource is a flow run with a name starting with certain prefixes. 2. Set Expected Events: After filtering, you determine if the event counts towards triggering an action. You specify the event names you expect and set a threshold for how many such events should occur within a given time frame. 3. Use After for Complex Scenarios: This allows for more complex event reactivity, ensuring that certain conditions are met before triggering actions, such as waiting for specific events to occur before proceeding. For more detailed examples and configurations, you can refer to the Prefect documentation on custom triggers and events. If you need to explore more about Prefect's API, you can check the top-level API which includes functions and classes such as
