swift (2.3.0)
* Erasure Code support (beta)
Swift now supports an erasure-code (EC) storage policy type. This allows
deployers to achieve very high durability with less raw capacity as used
in replicated storage. However, EC requires more CPU and network
resources, so it is not good for every use case. EC is great for storing
large, infrequently accessed data in a single region.
Swift's implementation of erasure codes is meant to be transparent to
end users. There is no API difference between replicated storage and
EC storage.
To support erasure codes, Swift now depends on PyECLib and
liberasurecode. liberasurecode is a pluggable library that allows for
the actual EC algorithm to be implemented in a library of your choosing.
As a beta release, EC support is nearly fully feature complete, but it
is lacking support for some features (like multi-range reads) and has
not had a full performance characterization. This feature relies on
ssync for durability. Deployers are urged to do extensive testing and
not deploy production data using an erasure code storage policy.
Full docs are at http://swift.openstack.org/overview_erasure_code.html
* Add support for container TempURL Keys.
* Make more memcache options configurable. connection_timeout,
pool_timeout, tries, and io_timeout are all now configurable.
* Swift now supports composite tokens. This allows another service to
act on behalf of a user, but only with that user's consent.
See http://swift.openstack.org/overview_auth.html for more details.
* Multi-region replication was improved. When replicating data to a
different region, only one replica will be pushed per replication
cycle. This gives the remote region a chance to replicate the data
locally instead of pushing more data over the inter-region network.
* Internal requests from the ratelimit middleware now properly log a
swift_source. See http://swift.openstack.org/logs.html for details.
* Improved storage policy support for quarantine stats in swift-recon.
* The proxy log line now includes the request's storage policy index.
* Ring checker has been added to swift-recon to validate if rings are
built correctly. As part of this feature, storage servers have learned
the OPTIONS verb.
* Add support of x-remove- headers for container-sync.
* Rings now support hostnames instead of just IP addresses.
* Swift now enforces that the API version on a request is valid. Valid
versions are configured via the valid_api_versions setting in swift.conf
* Various other minor bug fixes and improvements.
swift (2.2.2)
* Data placement changes
