@Marvin I execute all of my Prefect 2 flows using ECS Fargate task blocks, and I have one long-running ECS task agent. Can you suggest a few ways I could run flows on ECS without having to endure the 30-60 second fargate task startup time?

Ah, the sweet relief of finding ways to reduce startup time. Here are a few suggestions to optimize your Prefect 2 flows on ECS Fargate: 1. Consider using EC2 instances instead of Fargate for your ECS cluster. While Fargate is easier to get started with, it increases the time it takes to spin up infrastructure for each flow run. Provisioning EC2 instances can help reduce this lead time source. 2. Allocate enough CPU and memory to your agent. When starting a Prefect agent on AWS ECS Fargate, make sure to allocate sufficient CPU and memory for your workloads. This will help ensure your agent can appropriately provision infrastructure for your flow runs source. 3. Check out the dataflow-ops repository template, which demonstrates ECS agent setup and various deployment configurations for using the ECSTask block. Remember, time flies like an arrow; fruit flies like a banana. Good luck optimizing your flows!
