Future features

Object Storage Swift API related functionality

• chunking -> http://docs.openstack.org/api/openstack-object-storage/1.0/content/chunked-transfer-encoding.html
• CORS -> https://docs.openstack.org/swift/latest/cors.html
• Content encoding -> http://docs.openstack.org/api/openstack-object-storage/1.0/content/enabling-file-compression-with-content-encoding-header.html
• Content disposition (ie, bypassing content handling in the browser, and forcing file save) -> http://docs.openstack.org/api/openstack-object-storage/1.0/content/enabling-browser-bypass-with-content-disposition-header.html
• Versioning -> https://docs.openstack.org/swift/latest/overview_object_versioning.html
• Fine-grained authorization on containers -> https://docs.openstack.org/swift/latest/overview_acl.html
• Pseudo-hierarchies (to emulate directory structures) -> specifically, example 4.36/4.37 (path and delimiter) in http://docs.openstack.org/api/openstack-object-storage/1.0/content/folders-directories.html
• Automatically apply Swift convention for large objects, which is to store segmented objects separate from the manifests into a "_segments"-postfixed container: https://docs.openstack.org/swift/latest/overview_large_objects.html

Wishlist for JOSS separate from Object Storage functionality

• Content-sniffing; make content-sniffing (as opposed to file extension matching) a part of JOSS
• Persistable in-memory Object Store; useful if a server is running on in-memory object store and wants to persist its state after a server restart
• Method for asking whether an object's metadata has been read

Grizzly

• Added support for large objects with static manifests: http://docs.openstack.org/developer/swift/misc.html#module-swift.common.middleware.slo
• Support for the OPTIONS verb: Clients can use the OPTIONS verb as defined in http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
• Added support for CORS requests: http://www.w3.org/TR/cors/
• Bulk requests
  • Added support for auto-extracting archive uploads: A client can upload an archive file (ie a .tar file) and the contents will be stored individually in the cluster
  • Added support for bulk deletes: A client can delete many objects with one delete request
• Support for multi-range requests: Clients can request multiple ranges from an object with just one request
• Quotas
  • Added user-managed container quotas
  • Added support for account-level quotas (managed by an auth reseller)
• Swift now returns 406 if it cannot satisfy the Accept header
