Hi Yaqi, I have a few questions after my first pass:

1. I noticed a few outstanding v2 SDK references that may or may not be an issue (I'm unsure). Can you let me know what you think?

• One example
• .dockerignore --> should this just be build instead of v2/build? Or maybe we can just append build to the list?
• Do we want to update the imports/namespace references in the components/ directory? (Example)
• Do we want to update the v2 imports (and namespace) in the pipelines/frontend/mock-backend/data/v2/pipeline/ directory (example)?

2. Can you explain why we want to keep the v2/ directory with only an empty __init__.py file? Is it possible to remove this? Tests pass when this is removed.

Thanks for the review!

1. Edited the first one, for dockerignore, it refers to the backend folders.
2. For empty init, we will provide possible redirects in next PR, for current users to migrate. Thanks for pointing it out! @connor-mccarthy
