Basho Technologies is a distributed systems company that develops a key-value NoSQL database technology, Riak, and an object storage system that is built on the Riak platform, called Riak CS. == Technology and Products == Basho is the developer of Riak, an open source distributed database that offers high availability, fault tolerance, operation simplicity and scalability. Riak Enterprise is a commercial version of the database offered by Basho, the project's sponsor, with advanced multi-data center replication and enterprise support. Riak is a key value store system that can collect unstructured data and store it as objects in buckets that can then be queried. It's also highly scalable, able to distribute itself over a server cluster and add new servers as needed, while maintaining its own high availability. Riak is written in Erlang, a language that gives a system built-in support for distribution across a server cluster, fault tolerance, and an ability to absorb new hardware being added to the cluster without disrupting operations. Basho also offers Riak Cloud Storage (CS), an open source multi-tenant cloud storage database, built on the Riak platform, that integrates with private clouds and public clouds such as Amazon Web Services (AWS). It can be used by enterprises to power internal private clouds and by startups with an Amazon-compatible API for their own download service. Riak CS includes large object support, S3-compatible API and authentication, multi-tenancy and per-user reporting, an operational model for adding capacity, and a visual interface for monitoring and metrics. Riak 1.0 was released in September 2011 and featured secondary indexes, Riak Pipe, Riak Search integration, Lager, and LevelDB support. Riak 1.1 was released in early 2012 and included numerous changes to Riak Core, a new ownership claim algorithm, Riak KV improvements and MapReduce improvements. In August 2012, Riak 1.2 was released. Riak Enterprise 1.2 added SSL encryption, better balancing and more granular control of replication across multiple data centers. In March 2013, Basho released portions of Riak CS code to open source. Basho also announced the commercial version of Riak CS Enterprise, adding multi-datacenter replication, monitoring tools, and 24x7 support. Riak 1.4 features PN-Counters, which is the database's first distributed data type, which are eventually consistent and can be incremented and decremented on any node across the cluster. It has a compact binary data format that reduces storage overheads connected with small objects or large bucket names. Riak CS 1.4 provides compatibility with OpenStack, OpenStack Object Storage (Swift) and CEPH object stores with increased scalability. Riak 2.0 was released in September 2014 and includes support for new data types, tunable consistency and search integration with Apache Solr. Riak 2.1 was released in April 2015 and focussed on further performance and simplification for both developers and system administrators 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Basho Technologies」の詳細全文を読む スポンサード リンク
