Running deployments with concurrency or rate limits in Prefect 2 and Prefect 3 is a topic that excites me because it involves optimizing your workflows for performance and resource management!
These features allow you to efficiently manage the number of concurrent tasks or the rate at which tasks are executed, which is crucial for both system stability and efficient use of computational resources. It can be particularly useful in scenarios where systems have limits on the number of requests you can send or when interacting with rate-limited APIs.
Let me find the proper guidance for both Prefect 2.x and Prefect 3.x so I can provide you with precise instructions on how to set these up. I'll search the documentation and related GitHub issues to gather the most relevant information for both versions.
It seems I forgot to specify the queries for the documentation search. Let's try that again by searching for specific queries related to concurrency and rate limits in Prefect 2.x and 3.x. I'll focus on finding documentation on setting up these configurations for deployments.
Here's how you can manage deployments with concurrency or rate limits in both Prefect 2 and Prefect 3:
Prefect 2.x:
-
Concurrency Limits: You can manage concurrency limits through the Prefect UI and CLI. The guide on
Global Concurrency Limits explains that you can set parameters such as the concurrency limit itself, slot decay (a feature of rate limiting), and check the number of active slots.
-
Rate Limits: Managing rate limits can protect your API usage and ensure your application's resilience. The
API Rate Limits documentation outlines the limits in place for personal and Pro accounts and discusses how these limits function.
Prefect 3.x:
-
Concurrency and Rate Limits: Prefect 3 allows you to manage these limits in a similar manner to Prefect 2, either through the UI, CLI, or the Python SDK. More details can be found in the
Global Concurrency Limits section. This includes how to configure parameters like
slot_decay_per_second
to control the rate of slot refreshing, effectively implementing rate limiting.
-
Task Run Limits: Documentation on
Task Run Limits further helps in defining constraints on how many tasks run concurrently.
In both versions, these features help optimize resource usage and ensure your workflows are efficient and stable. You can manage these settings via the Prefect tools to align with your operational needs.
