MariaDB is launching version 10 of its open source database today. It has woken up to the importance of giving its users access
to non-relational databases.
New in version 10 is the CONNECT engine, which can link up the MariaDB database system to outside sources of data, and Cassandra-compatibility
Maria DB 'CONNECT' can access information managed by NoSQL software, such as Riak and MongoDB, offering system admins read/write access
to various data sets through traditional SQL commands, along with some other features.
"With CONNECT, MariaDB has one of the most advanced implementations of Management of External Data (MED) without the need of complex
additions to the SQL syntax (foreign tables are "normal" tables using the CONNECT engine)," said Team MariaDB.
It's worth noting that MySQL has had a similar capability for several years via its implementation of the Mem Cached API for slurping
NoSQL data into its InnoDB storage engine.
This technology also offers MySQL developers a way to link NoSQL web applications into MySQL infrastructure, allowing them to present
and further integrate with modern applications built with these systems without having to indulge in the long and complex migration of a
Additionally, with version 10, system admins can access data directly from NoSQL Cassandra databases within open-source MariaDB.
Besides the CONNECT engine and Cassandra capabilities, MariaDB version 10 also has new features based on technology developed at Google
(parallel replication), and Chinese web giant Taobao (per-thread memory usage, multi-source replication) and it's also gained dynamic columns.
Alongside the release, major MariaDB developer SkySQL released the second version of its "Enterprise" paid-for distribution of the
technology. This backs MariaDB installs with a subscription-based support policy.
"What we now offer is, along with the MariaDB ten launch and going forward, an enterprise-grade distribution. That means number one
support. The vast majority of support is more consultative than it is break-fix," explained SkySQL's vice president of product management
Roger Levy. The MariaDB Enterprise version costs $5,000 per server per year.
The purpose of the MariaDB Foundation is to ensure that there is not just one person or one company that is driving MariaDB/MySQL development.
It is the custodian of the MariaDB code and guardian of the MariaDB community.
The MariaDB Foundation also holds the trademark of the MariaDB server. This ensures that the official MariaDB development tree will
always be open for the MariaDB developer community.
It's the MariaDB Foundation that ensures that all community patches, including MySQL source code, are merged into MariaDB. It also does
the builds and QA of MariaDB and provides a lot of the MariaDB documentation.

Data storage system provider Scality said earlier this morning that it's developing its RING object storage platform to use Seagate’s
Kinetic family of drives.
These disk drives implement an on-board key/value store and are directly accessed over Ethernet networks using Get and Put requests.
Each drive has two 1 Gbit/s Ethernet ports that are both easy to configure. Scality’s RING storage device appliance uses scale-out nodes
that can grow to multi-petabyte levels of data storage capacity.
Overall, Seagate has developed its Kinetic drives with the goal of rendering a storage array controller layer-- what Seagate calls the
storage server tier, in the application-to-disk-access stack redundant, and thus giving large scale/big data storage providers a more cost-effective
Scality CEO Jerome Lecat says-- “The Seagate Kinetic Open Storage platform represents exactly the kind of innovation required to achieve
the full promise of the Software-Defined Data Centre.”
There are few details, however. We know Scality is testing its Kinetic RING in the Rausch Netzwerktechnik Bigfoot Object Storage Solution
(BOSS) which is aimed at scale-out cloud customers.
A BOSS 4U chassis contains 72 disk drives, according to the Seagate release giving 288 TB. It uses Seagate’s 4 TB Kinetic drives. A BOSS
Rack of 10 x 4U chassis provides 2.8 PB of data storage capacity.
The 4U chassis has an Ethernet switch on its backplane. We wrote about Seagate and Rausch Netzwerktechnik GmbH in early March. Now
Scality has been revealed as being involved as well.
The Rausch website has an added BigFoot Object storage product, added to the XXL and JBOD variants we mentioned before. There are
also BigFoot XXFast and XXCold products.
The BOSS object storage text on the site says each drive has its own IP address. Scality storage is based on a ring structure of X86
server nodes that store objects and operate in parallel.
The servers provide the storage media. It must be modifying its RING disk storage access to talk to the Kinetic drives via
Gets and Puts. We might imagine that each Scality X86 node could have an Ethernet-attached 4U BOSS chassis.
There is clearly a lot of processing to do with object storage and thus the balance between x86 CPU/memory resources and the amount
of storage must be considered, otherwise you could load a single X86 server with a rack of disks.
So we need to think about adding the requisite RING X86 server nodes as well. In effect you might think, you would need 1U of server
resource per 4U or 8U JBOD of Kinetic drives.

Western Digital is now making a new portable external drive dubbed 'My Passport Pro' while the power is delivered over the data
The new external drive comes in 2 TB and 4 TB configurations using two 2.5-inch drives, with either RAID 0 (striping) or RAID 1
(mirroring) for MAC users.
RAID 0 delivers up to 233 MB/sec bandwidth with the 2 TB unit and a somewhat lower 230MB/sec with the 4 TB unit, using the integrated
Western Digital says that's roughly twice as fast as USB 3.0 with RAID 0 set, when transferring a 22 GB high-definition video file.
Overall, the enclosure looks similar to a thicker 'My Passport Ultra' which runs up to a 2 TB capacity.
Western Digital says that the Pro My Passport, which it claims is the first Thunderbolt-powered dual-drive portable, is for
creative professionals and enthusiasts.
Jim Welsh, WD executive vice president for branded products talked of photographers, videographers and musicians to graphic designers
and architects, people who depend on portable storage for their livelihood.
They can generate and process large files of digital outside the studio faster than before. This My Passport Pro is available now at
Apple and major consumer electronics retailers and e-tailers.
The MSRP for the 2 TB My Passport Pro is US $399 and US $579 for the 4 TB model. You can also purchase them online on the company's
