Post as a guest Name. Email Required, but never shown.MinIO is a high performance, distributed object storage system. MinIO is different in that it was designed from its inception to be the standard in private cloud object storage.

Because MinIO is purpose-built to serve only objects, a single-layer architecture achieves all of the necessary functionality without compromise. The result is a cloud-native object server that is simultaneously performant, scalable and lightweight. While MinIO excels at traditional object storage use cases like secondary storage, disaster recovery and archiving, it is unique at overcoming the private cloud challenges associated with machine learning, analytics and cloud-native application workloads.

From the AWS S3 API to S3 Select and our implementations of inline erasure coding and security, our code is widely admired and frequently copied by some of the biggest names in technology and business. MinIO protects data with per-object, inline erasure coding, which is written in assembly code to deliver the highest performance possible. This means that in a 12 drive setup, an object is sharded across as 6 data and 6 parity blocks.

MinIO's implementation ensures that objects can be read or new objects are written even if multiple devices are lost or unavailable. Finally, MinIO's erasure code is at the object level and can heal one object at a time.

It is one thing to encrypt data in flight; it is another to protect data at rest. MinIO supports multiple, sophisticated server-side encryption schemes to protect data - wherever it may be. Encrypted objects are tamper-proofed with AEAD server side encryption.

Additionally, MinIO is compatible with and tested against all commonly used Key Management solutions e. HashiCorp Vault. Given the exceptionally low overhead, auto-encryption can be turned on for every application and instance. The means that data once written becomes tamper-proof. This has practical applications for many different regulatory requirements. MinIO supports the most advanced standards in identity management, integrating with the OpenID connect compatible providers as well as key external IDP vendors.

That means that access is centralized and passwords are temporary and rotated, not stored in config files and databases. Furthermore, access policies are fine grained and highly configurable, which means that supporting multi-tenant and multi-instance deployments become simple. The challenge with traditional replication approaches is that they do not scale effectively beyond a few hundred TB.

Having said that, everyone needs a replication strategy to support disaster recovery and that strategy needs to span geographies, data centers and clouds. By leveraging Lambda compute notifications and object metadata it can compute the delta efficiently and quickly. Lambda notifications ensure that changes are propagated immediately as opposed to traditional batch mode.

Continuous replication means that data loss will be kept to a bare minimum should a failure occur - even in the face of highly dynamic datasets. Finally, like all that MinIO does, continuous replication is multi-vendor, meaning that your backup location can be anything from NAS to the public cloud. The modern enterprise has data everywhere.

MinIO allows those various instances to be combined to form a unified global namespace. The impact of this approach is that an object store can scale massively for large, geographically distributed enterprise while retaining the ability to accommodate a variety of applications S3 Select, MinSQL, Spark, Hive, Presto, TensorFlow, H20 from a single console.

All enterprises are adopting a multi-cloud strategy. This also includes private clouds. As a result, your bare-metal virtualization containers and public cloud services including non-S3 providers like Google, Microsoft and Alibaba have to look identical. While the modern application is highly portable, the data that powers those applications is not.

Making that data available, wherever it may reside, is the primary challenge that MinIO addresses. MinIO runs on bare metal, network attached storage and every public cloud.

To run mc against other S3 compatible servers, start the container this way:. Source installation is intended only for developers and advanced users.

If you do not have a working Golang environment, please follow How to install Golang. To add one or more Amazon S3 compatible hosts, please follow the instructions below.

Object Storage - the key to Cloud and Big Data

Alias is simply a short name to your cloud storage service. S3 end-point, access and secret keys are supplied by your cloud storage provider. API signature is an optional argument. By default, it is set to "S3v4". It is a hosted MinIO server for testing and development purpose. To test Amazon S3, simply replace "play" with "s3" or the alias you used at the time of setup.

Use --incomplete flag to list partially copied content. On a filesystem, it behaves like mkdir -p command. Bucket is equivalent of a drive or mount point in filesystems and should not be treated as folders. MinIO does not place any limits on the number of buckets created per user.

On Amazon S3, each account is limited to buckets. Please refer to Buckets Restrictions and Limitations on S3 for more information. On a filesystem, it behaves like rmdir command. Note that when a bucket is removed all policies associated with the bucket will also be removed. If you would like to just empty the objects in a bucket use rm command. You may also use it to simply display the contents to stdout. Example: Display the contents of a server encrypted object myencryptedobject.

Pass base64 encoded string if encryption key contains non-printable character like tab.

For more query examples refer to official AWS S3 documentation here. Example: Display the first line of a server encrypted object myencryptedobject. Example: Set object lock configuration of 30 day compliance on bucket mybucket.

Example: Set governance for 30 days for object prefix on bucket mybucket.Using MinIO build high performance infrastructure for machine learning, analytics and application data workloads. Generally, it is not recommended to use default keys with containers. Please visit MinIO Docker quickstart guide for more information here. Source installation is only intended for developers and advanced users.

If you do not have a working Golang environment, please follow How to install Golang. Minimum version required is go1. By default MinIO uses the port to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port. Use below command to allow access to port For hosts with ufw enabled Debian based distrosyou can use ufw command to allow traffic to specific ports.

Note that permanent makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect. MinIO Server comes with an embedded web based object browser. It supports filesystems and Amazon S3 compatible cloud storage services. When deployed on a single drive, MinIO server lets clients access any pre-existing data in the data directory.

MinIO server supports rolling upgrades, i. This allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However, we recommend all our users to use mc admin update from the client. This will update all the nodes in the cluster and restart them, as shown in the following command from the MinIO client mc :.In the first part of this series, we saw why object storage systems like Minio are the perfect approach to build modern data lakes that are agile, cost-effective, and massively scalable.

One of the design principles of object storage is to abstract some of the lower layers of storage away from the administrators and applications. Thus, data is exposed and managed as objects instead of files or blocks.

Objects contain additional descriptive properties which can be used for better indexing or management. Administrators do not have to perform lower-level storage functions like constructing and managing logical volumes to utilize disk capacity or setting RAID levels to deal with disk failure.

Object storage also allows the addressing and identification of individual objects by more than just file name and file path. Object storage adds a unique identifier within a bucket, or across the entire system, to support much larger namespaces and eliminate name collisions.

Object storage explicitly separates file metadata from data to support additional capabilities. As opposed to fixed metadata in file systems filename, creation date, type, etc.

Use Minio documentation to deploy Minio on your preferred platform. Then, follow the steps to see how to integrate Minio with Hadoop. We need to make changes in core-site. Instead we need to use another protocol, and most commonly used one is s3a. S3 stands for Simple Storage Service, created by Amazon and is widely used as access protocol for object storage. Hence in core-site. Refer the below file for details and update it into core-site.

Note that you also need to match your Hadoop version with the jar files you download. I used Hadoop version 3. These are the jar files needed :. Note that this is needed only if you want to use hdfs filesystem as well as s3a. Then enter. Check the Minio browser now, you should see the file in bucket mydemobucket. Alsotry hadoop fs —cat command on any file that you may have:.

Execute following command with appropriate change to your data file location and name. Make sure you bring the data to be copied to your local. Please note that you must give upto parent directory, not the file name.

I have highlighted the error message you may get when you give filename. You have now created a HIVE table from s3 data. That means, with the underlying file system as S3, we can create a data warehouse without the dependency on HDFS. You may now require another important component: How to combine data with an already existing system, when you move to Object Storage? Follow the deployment instructions.

At the minimum, we need the presto server and presto client for accessing the server.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The mc ls command is equivalent to the aws ls command and not the aws head-object call, so this is working as intended. Sorry if I wasn't clear. This is a feature request, not a bug. At the moment there is no way to retrieve user metadata through the mc utility.

Requesting user metadata might be really expensive operation on large buckets are you sure you want this information? Please see the example I posted above, the request is to retrieve metadata for one specific object only. I understand what you mean wholly. I want to suggest a better alternative for you to look at object metadata through populating your namespace to a query friendly backend. This can be achieved by using the previously referenced documentation.

This option is not useful for mc and will be seldomly used IMO. You need to provide a stronger use case otherwise we prefer to avoid adding rarely used options. S3 object metadata is probably the most important feature of self-hosted object storage, so i'm sure many people would appreciate at least being able to retrieve it even if only for testing.

Since the --debug flag is a seldomly used feature, perhaps it would make sense to include user metadata when specifying --debug? What do you think?

We decided to implement this as a new sub command such as mc stat which has variations like mc stat --recursive which can pretty much give you the metadata information about each objects.
