Hi all! My team is laboring between the decision to fully commit to zero-downtime schema change operations resulting in needing to fully reindex the new collection and then point the alias to it, and allowing acceptable write-blocking schema changes. Is there information somewhere about "how long" an operation like "adding a new field" or "deleting a field" against a collection with data in it would take, ie how long write operations would be blocked for? I think this is a crux that will help us decide. Thank you!
