Hi, I have a quick question regarding fast registration via flytectl. According to docs, there is no difference between regular and fast registration - so does that mean that if there are no python dependency changes and I want to use fast registration, then I can add

--fast

flag to my

pyflyte package ...

command, but leave the

flytectl register files …

command the same and then forego the docker build process?

That’s correct 👍 I think you might also need to use

pyflyte ... serialize fast

beforehand 🙂 Under the hood, this will create a zip file with all your modules code which is then uploaded to your blob storage together with the workflow and task definitions

Hi @agreeable-kitchen-44189 thanks! But I’m not sure what you mean by

pyflyte serialize

? I’ve always only done

pyflyte package

to output

flyte-packages.tgz

and then

flytectl register files --archive flyte-packages.tgz

- do I need to run another command besides these?

I think in the case of

pyflyte package

you’ll need the

--fast

flag to get to the same result

OK so no need for

pyflyte serialize

?

Yep 👍 If I’m not mistaken

pyflyte package

is the newer version that replaces

pyflyte serialize

Sorry I missed this - I think there’s a difference there (based on the docs anyway). Not sure exactly, but if used in a team, I think flytectl is preferred?
