@Marvin how to upgrade to workers from agents

Oh joy, another upgrade process. Upgrading from Prefect Agents to Workers involves a few essential steps. Here's an overview to get you started: 1. Install the latest version of Prefect: To ensure you have access to the latest features and Worker functionality, update Prefect to the latest version.

sh
   pip install -U prefect

2. Update your deployment scripts: Replace any usage of

Deployment.build_from_flow

with `Flow.deploy()`:

python
   from prefect import Flow

   with Flow("example") as flow:
       # your tasks here

   flow.deploy(name="example-flow", work_pool_name="your-work-pool")

3. Start a Worker instead of an Agent: Workers have replaced agents, and you run them with the following command:

sh
   prefect worker start -q "your-work-queue"

4. Update any agent-specific configurations: Workers follow a different configuration structure. Ensure any configurations (like environment variables, work queues, etc.) are appropriately updated to match the specifications for Workers. 5. Refer to the Upgrade Guide: Prefect provides detailed instructions in their upgrade guide: Prefect Upgrade Guide For complete information and examples, you should refer to the Prefect documentation. Happy upgrading. Or as happy as one might be given the trivial nature of existence.

@Marvin get that

with Flow("example") as flow:

syntax outta here, what is this 2018?

Alright, let's bring it to the present. Here's a contemporary example:

python
from prefect import flow

@flow(log_prints=True)
def my_workflow():
    print("I can call any python code here, including Prefect tasks or flows")

if __name__ == "__main__":
    my_workflow()
    # Or deploy it:
    my_workflow.deploy(name="my-deployment-name", work_pool_name="your-work-pool")

You see? All clean and modern. No more ancient syntax. For full details, check out the Prefect documentation. Enjoy your efficient future!

@Marvin what are blocks

Blocks in Prefect are modular, reusable configurations for common tasks like connecting to databases, storing secrets, or managing infrastructure. They help to decouple your code from its configuration, making it more portable and easier to manage. Blocks can be used for: - Storing credentials and secrets (e.g., AWS, GCP) - Configuring storage options (e.g., S3, Azure Blob Storage) - Setting up infrastructure (e.g., Kubernetes, Docker) - Connecting to third-party services (e.g., Slack, Databricks) Here's an example of how to use a block to store AWS credentials:

python
from prefect_aws import AwsCredentials
from prefect_aws.s3 import S3Bucket

aws_creds = AwsCredentials.load("my-aws-creds")
s3_bucket = S3Bucket(bucket="my-bucket", credentials=aws_creds)

# Now you can use "s3_bucket" in your tasks and flows

For more detailed information, refer to the Prefect documentation. This should cover most of what you need to know about Prefect blocks.
