This PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.
This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.
Some design details and restrictions:
- Objects are distributed using consistent ordering
to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
requirement, you can start with multiple
such sets statically.
- Static sets set of disks and cannot be
changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
slower since List happens on all servers,
and is merged at this sets layer.

in-memory caching cannot be cleanly implemented
without the access to GC which Go doesn't naturally
provide. At times we have seen that object caching
is more of an hindrance rather than a boon for
our use cases.
Removing it completely from our implementation
related to #5160 and #5182
This is a generic minimum value. The current reason is to support
Azure blob storage accounts name whose length is less than 5. 3 is the
minimum length for Azure.
This change adds documentation about PKCS-8 vs PKCS-1 pitfalls. It
also provides a command to convert encrypted PKCS-8 RSA keys to
encrypted PKCS-1 RSA keys.
Fixes#5453
If STANDARD storage class is set before starting up Minio server,
but x-amz-storage-class metadata field is not set in a PutObject
request, Minio server defaults to N/2 data and N/2 parity disks.
This PR changes the behaviour to use data and parity disks set in
STANDARD storage class, even if x-amz-storage-class metadata
field is not present in PutObject requests.
Manta has the ability to allow users to authenticate with a
username other than the main account. We want to expose
this functionality to minio manta gateway.
This change adds support for password-protected private keys.
If the private key is encrypted the server tries to decrypt
the key with the password provided by the env variable
MINIO_CERT_PASSWD.
Fixes#5302
- Add storage class metadata validation for request header
- Change storage class header values to be consistent with AWS S3
- Refactor internal method to take only the reqd argument
This adds configurable data and parity options on a per object
basis. To use variable parity
- Users can set environment variables to cofigure variable
parity
- Then add header x-amz-storage-class to putobject requests
with relevant storage class values
Fixes#4997
Manta is an Object Storage by [Joyent](https://www.joyent.com/)
This PR adds initial support for Manta. It is intended as non-production
ready so that feedback can be obtained.
Ever since commit 5db1e9f3dd the
default region as been '', instead of 'us-east-1'. Update
documentation to reflect this, in particular, documentation about
notifications.
With https://github.com/minio/minio/pull/4869 maximum size of a single
multipart upload part in not restricted to 100MB. 1TB maximum object
size limitation is no longer applicable too.
This implementation is similar to AMQP notifications:
* Notifications are published on a single topic as a JSON feed
* Topic is configurable, as is the QoS. Uses the paho.mqtt.golang
library for the mqtt connection, and supports connections over tcp
and websockets, with optional secure tls support.
* Additionally the minio server configuration has been bumped up
so mqtt configuration can be added.
* Configuration migration code is added with tests.
MQTT is an ISO standard M2M/IoT messaging protocol and was
originally designed for applications for limited bandwidth
networks. Today it's use is growing in the IoT space.
This patch also reverts previous changes which were
merged for migration to the newer disk format. We will
be bringing these changes in subsequent releases. But
we wish to add protection in this release such that
future release migrations are protected.
Revert "fs: Migration should handle bucketConfigs as regular objects. (#4482)"
This reverts commit 976870a391.
Revert "fs: Migrate object metadata to objects directory. (#4195)"
This reverts commit 76f4f20609.
This PR also does backend format change to 1.0.1
from 1.0.0. Backward compatible changes are still
kept to read the 'md5Sum' key. But all new objects
will be stored with the same details under 'etag'.
Fixes#4312
public.crt needs sometimes to have a chain certificate, this PR
explains how to construct public.crt when certificate are issued
by a certificate authority.
This change adds `access` format support for notifications to a
Elasticsearch server, and it refactors `namespace` format support.
In the case of `access` format, for each event in Minio, a JSON
document is inserted into Elasticsearch with its timestamp set to the
event's timestamp, and with the ID generated automatically by
elasticsearch. No events are modified or deleted in this mode.
In the case of `namespace` format, for each event in Minio, a JSON
document is keyed together by the bucket and object name is updated in
Elasticsearch. In the case of an object being created or over-written
in Minio, a new document or an existing document is inserted into the
Elasticsearch index. If an object is deleted in Minio, the
corresponding document is deleted from the Elasticsearch index.
Additionally, this change upgrades Elasticsearch support to the 5.x
series. This is a breaking change, and users of previous elasticsearch
versions should upgrade.
Also updates documentation on Elasticsearch notification target usage
and has a link to an elasticsearch upgrade guide.
This is the last patch that finally resolves#3928.
