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
