Spark/Hadoop workloads which use Hadoop MR
Committer v1/v2 algorithm upload objects to a
temporary prefix in a bucket. These objects are
'renamed' to a different prefix on Job commit.
Object storage admins are forced to configure
separate ILM policies to expire these objects
and their versions to reclaim space.
Our solution:
This can be avoided by simply marking objects
under these prefixes to be excluded from versioning,
as shown below. Consequently, these objects are
excluded from replication, and don't require ILM
policies to prune unnecessary versions.
- MinIO Extension to Bucket Version Configuration
```xml
<VersioningConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Status>Enabled</Status>
<ExcludeFolders>true</ExcludeFolders>
<ExcludedPrefixes>
<Prefix>app1-jobs/*/_temporary/</Prefix>
</ExcludedPrefixes>
<ExcludedPrefixes>
<Prefix>app2-jobs/*/__magic/</Prefix>
</ExcludedPrefixes>
<!-- .. up to 10 prefixes in all -->
</VersioningConfiguration>
```
Note: `ExcludeFolders` excludes all folders in a bucket
from versioning. This is required to prevent the parent
folders from accumulating delete markers, especially
those which are shared across spark workloads
spanning projects/teams.
- To enable version exclusion on a list of prefixes
```
mc version enable --excluded-prefixes "app1-jobs/*/_temporary/,app2-jobs/*/_magic," --exclude-prefix-marker myminio/test
```
introduce x-minio-force-create environment variable
to force create a bucket and its metadata as required,
it is useful in some situations when bucket metadata
needs recovery.
heal bucket metadata and IAM entries for
sites participating in site replication from
the site with the most updated entry.

- Allow proper SRError to be propagated to
handlers and converted appropriately.
- Make sure to enable object locking on buckets
when requested in MakeBucketHook.
- When DNSConfig is enabled attempt to delete it
first before deleting buckets locally.
- New sub-system has "region" and "name" fields.
- `region` subsystem is marked as deprecated, however still works, unless the
new region parameter under `site` is set - in this case, the region subsystem is
ignored. `region` subsystem is hidden from top-level help (i.e. from `mc admin
config set myminio`), but appears when specifically requested (i.e. with `mc
admin config set myminio region`).
- MINIO_REGION, MINIO_REGION_NAME are supported as legacy environment variables for server region.
- Adds MINIO_SITE_REGION as the current environment variable to configure the
server region and MINIO_SITE_NAME for the site name.
currently getReplicationConfig() failure incorrectly
returns error on unexpected buckets upon upgrade, we
should always calculate usage as much as possible.
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

- add checks such that swapped disks are detected
and ignored - never used for normal operations.
- implement `unrecognizedDisk` to be ignored with
all operations returning `errDiskNotFound`.
- also add checks such that we do not load unexpected
disks while connecting automatically.
- additionally humanize the values when printing the errors.
Bonus: fixes handling of non-quorum situations in
getLatestFileInfo(), that does not work when 2 drives
are down, currently this function would return errors
incorrectly.
This change allows a set of MinIO sites (clusters) to be configured
for mutual replication of all buckets (including bucket policies, tags,
object-lock configuration and bucket encryption), IAM policies,
LDAP service accounts and LDAP STS accounts.
In (erasureServerPools).MakeBucketWithLocation deletes the created
buckets if any set returns an error.
Add `NoRecreate` option, which will not recreate the bucket
in `DeleteBucket`, if the operation fails.
Additionally use context.Background() for operations we always want to be performed.
- Supports object locked buckets that require
PutObject() to set content-md5 always.
- Use SSE-S3 when S3 gateway is being used instead
of SSE-KMS for auto-encryption.
This PR however also proceeds to simplify the loading
of various subsystems such as
- globalNotificationSys
- globalTargetSys
converge them directly into single bucket metadata sys
loader, once that is loaded automatically every other
target should be loaded and configured properly.
fixes#13252
- deletes should always Sweep() for tiering at the
end and does not need an extra getObjectInfo() call
- puts, copy and multipart writes should conditionally
do getObjectInfo() when tiering targets are configured
- introduce 'TransitionedObject' struct for ease of usage
and understanding.
- multiple-pools optimization deletes don't need to hold
read locks verifying objects across namespace and pools.
This happens because of a change added where any sub-credential
with parentUser == rootCredential i.e (MINIO_ROOT_USER) will
always be an owner, you cannot generate credentials with lower
session policy to restrict their access.
This doesn't affect user service accounts created with regular
users, LDAP or OpenID
This feature also changes the default port where
the browser is running, now the port has moved
to 9001 and it can be configured with
```
--console-address ":9001"
```
Also adding an API to allow resyncing replication when
existing object replication is enabled and the remote target
is entirely lost. With the `mc replicate reset` command, the
objects that are eligible for replication as per the replication
config will be resynced to target if existing object replication
is enabled on the rule.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
attempt a delete on remote DNS store first before
attempting locally, because removing at DNS store
is cheaper than deleting locally, in case of
errors locally we can cheaply recreate the
bucket on dnsStore instead of.
This commit adds support for SSE-KMS bucket configurations.
Before, the MinIO server did not support SSE-KMS, and therefore,
it was not possible to specify an SSE-KMS bucket config.
Now, this is possible. For example:
```
mc encrypt set sse-kms some-key <alias>/my-bucket
```
Further, this commit fixes an issue caused by not supporting
SSE-KMS bucket configuration and switching to SSE-KMS as default
SSE method.
Before, the server just checked whether an SSE bucket config was
present (not which type of SSE config) and applied the default
SSE method (which was switched from SSE-S3 to SSE-KMS).
This caused objects to get encrypted with SSE-KMS even though a
SSE-S3 bucket config was present.
This issue is fixed as a side-effect of this commit.

This commit replaces the custom KES client implementation
with the KES SDK from https://github.com/minio/kes
The SDK supports multi-server client load-balancing and
requests retry out of the box. Therefore, this change reduces
the overall complexity within the MinIO server and there
is no need to maintain two separate client implementations.

This commit adds basic SSE-KMS support.
Now, a client can specify the SSE-KMS headers
(algorithm, optional key-id, optional context)
such that the object gets encrypted using the
SSE-KMS method. Further, auto-encryption now
defaults to SSE-KMS.
This commit does not try to do any refactoring
and instead tries to implement SSE-KMS as a minimal
change to the code base. However, refactoring the entire
crypto-related code is planned - but needs a separate
effort.

With this change, MinIO's ILM supports transitioning objects to a remote tier.
This change includes support for Azure Blob Storage, AWS S3 compatible object
storage incl. MinIO and Google Cloud Storage as remote tier storage backends.
Some new additions include:
- Admin APIs remote tier configuration management
- Simple journal to track remote objects to be 'collected'
This is used by object API handlers which 'mutate' object versions by
overwriting/replacing content (Put/CopyObject) or removing the version
itself (e.g DeleteObjectVersion).
- Rework of previous ILM transition to fit the new model
In the new model, a storage class (a.k.a remote tier) is defined by the
'remote' object storage type (one of s3, azure, GCS), bucket name and a
prefix.
* Fixed bugs, review comments, and more unit-tests
- Leverage inline small object feature
- Migrate legacy objects to the latest object format before transitioning
- Fix restore to particular version if specified
- Extend SharedDataDirCount to handle transitioned and restored objects
- Restore-object should accept version-id for version-suspended bucket (#12091)
- Check if remote tier creds have sufficient permissions
- Bonus minor fixes to existing error messages
