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`
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

- Add 32-bit checksum (32 LSB part of xxhash64) of the serialized metadata.
This will ensure that we always reject corrupted metadata.
- Add automatic repair of inline data, so the data structure can be used.
If data was corrupted, we remove all unreadable entries to ensure that operations
can succeed on the object. Since higher layers add bitrot checks this is not a big problem.
Cannot downgrade to v1.1 metadata, but since that isn't released, no need for a major bump.
versionID is the one that needs to be preserved and as
well as overwritten in case of replication, transition
etc - dataDir is an ephemeral entity that changes
during overwrites - make sure that versionID is used
to save the object content.
this would break things if you are already running
the latest master, please wipe your current content
and re-do your setup after this change.
