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.

* ring validator (in swift-recon): eg test that something is running on the ports in the ring -- not just "something", must verify correct type, because deployers sometimes flip a/c/o and then inexplicable 400 happens -- https://wiki.openstack.org/wiki/OutreachProgramForWomen/Ideas#Swift_-_storage_server_OPTIONS_support_and_checker_tool

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/

Etherpads from previous meetups/hackathons/Design Summits/PTGs are available at Swift/Etherpads
