I have high level design question: It is advisable to share the flow code between two deployments of the same flow? details in thread

09/28/2022, 4:21 PMIt looks like I could do this with the Python API:
Copy code
storage_block = S3.load("myfirstblock")
deploymentA = Deployment(
flow_name="FooFlow",
name="FooA",
parameters={"arg", "A"}
entrypoint="foo.py:foo"
storage=storage_block,
path="/foo_code"
)
deploymentA.apply()
deploymentA.upload_to_storage()
deployment = Deployment(
flow_name="FooFlow",
name="FooB",
parameters={"arg", "B"}
entrypoint="foo.py:foo"
storage=storage_block,
path="/foo_code"
)
deploymentB.apply()k

09/28/2022, 4:22 PMI am storing code in s3 for now.
I am going to have, for example, 100-200 deployments per flow (each with different arguments) so I would like to avoid making a separate upload for each deployment.
Is re-using code like this one of the intended ways Deployments are used, or am I doing off the rails?

09/28/2022, 4:23 PMit is desirable to have two deployments for the same flow?I'm asking specifically about whether its acceptable to have two deployments share the exact same chunk of flow code stored in S3.

09/28/2022, 4:24 PMFrom the docs it seems like that having multiple deployments per Flow registration is by design.

09/28/2022, 4:24 PMYes, deployment allows you to run a single flow with different parameters as explained here

09/28/2022, 4:25 PMThanks, I read that. That is not what I'm asking.

09/28/2022, 4:26 PMI would like to have two deployments (for the same flow), each with separate sets of default args (that may be overridden), but only upload the code to s3 once.

09/28/2022, 4:27 PMYou can skip uploading when building a deployment using the command
--skip-uploadd
