調査方針
Start by understanding the collection lifecycle in Milvus, focusing on the write and release mechanisms. Look at the codebase in the 'internal' directory for collection management. The issue outlines steps: disable writing, release collection, change collection ID, cleanup metadata, and await async garbage collection. There are two assignees, so check their linked work or comments. Review the garbage collection process for async data cleanup. The maintainers may have additional context in the comments (8 comments) about design decisions.
