= Ideas for OpenStack Swift =

This page is a collection of "brain dumps" for ideas about features in OpenStack Swift. If you're working on something, it's a very good idea to write down what you're thinking about. This lets others get up to speed, helps you collaborate, and serves as a great record for future reference. Write down your thoughts somewhere and put a link to it here. It doesn't matter what form your thoughts are in; use whatever is best for you. Your document should include why your idea is needed and your thoughts on particular design choices and tradeoffs. Please include some contact information (ideally, your IRC nick) so that people can collaborate with you.

Historic "specs" are available at https://specs.openstack.org/openstack/swift-specs/
