features:
|
|
- |
|
|
Added container sharding, an operator controlled feature that
|
|
may be used to shard very large container databases into a
|
|
number of smaller shard containers. This mitigates the issues
|
|
with one large DB by distributing the data across multiple
|
|
smaller databases throughout the cluster. Please read the full
|
|
overview at
|
|
https://docs.openstack.org/swift/latest/overview_container_sharding.html
|
|
|
|
- |
|
|
Provide an S3 API compatibility layer. The external "swift3"
|
|
project has been imported into Swift's codebase as the "s3api"
|
|
middleware.
|
|
|
|
- |
|
|
Added "emergency mode" hooks in the account and container replicators.
|
|
These options may be used to prioritize moving handoff
|
|
partitions to primary locations more quickly. This helps when
|
|
adding capacity to a ring.
|
|
|
|
- Added ``-d <devs>`` and ``-p <partitions>`` command line options.
|
|
|
|
- Added a handoffs-only mode.
|
|
|
|
- |
|
|
Add a multiprocess mode to the object replicator. Setting the
|
|
``replicator_workers`` setting to a positive value N will result
|
|
in the replicator using up to N worker processes to perform
|
|
replication tasks. At most one worker per disk will be spawned.
|
|
|
|
Worker process logs will have a bit of information prepended so
|
|
operators can tell which messages came from which worker. The
|
|
prefix is "[worker M/N pid=P] ", where M is the worker's index,
|
|
N is the total number of workers, and P is the process ID. Every
|
|
message from the replicator's logger will have the prefix
|
|
|
|
- |
|
|
The object reconstructor will now fork all available worker
|
|
processes when operating on a subset of local devices.
|
|
|
|
- |
|
|
Add support for PROXY protocol v1 to the proxy server. This
|
|
allows the Swift proxy server to log accurate client IP
|
|
addresses when there is a proxy or SSL-terminator between the
|
|
client and the Swift proxy server. Example servers supporting
|
|
this PROXY protocol include stunnel, haproxy, hitch, and
|
|
varnish. See the sample proxy server config file for the
|
|
appropriate config setting to enable or disable this
|
|
functionality.
|
|
|
|
- |
|
|
In the ratelimit middleware, account whitelist and blacklist
|
|
settings have been deprecated and may be removed in a future
|
|
release. When found, a deprecation message will be logged.
|
|
Instead of these config file values, set X-Account-Sysmeta-
|
|
Global-Write-Ratelimit:WHITELIST and X-Account-Sysmeta-Global-
|
|
Write-Ratelimit:BLACKLIST on the particular accounts that need
|
|
to be whitelisted or blacklisted. System metadata cannot be added
|
|
or modified by standard clients. Use the internal client to set sysmeta.
|
|
|
|
- |
|
|
Add a ``--drop-prefixes`` flag to swift-account-info,
|
|
swift-container-info, and swift-object-info. This makes the
|
|
output between the three more consistent.
|
|
|
|
- |
|
|
statsd error messages correspond to 5xx responses only. This
|
|
makes monitoring more useful because actual errors (5xx) will
|
|
not be hidden by common user requests (4xx). Previously, some 4xx
|
|
responses would be included in timing information in the statsd
|
|
error messages.
|
|
|
|
- |
|
|
Truncate error logs to prevent log handler from running out of buffer.
|
|
|
|
- |
|
|
Updated requirements.txt to match global exclusions and formatting.
|
|
|
|
- |
|
|
tempauth user names now support unicode characters.
|
|
|
|
- |
|
|
Various other minor bug fixes and improvements.
