You don’t have to wait for long… Oracle Introduces Oracle Exadata Storage Expansion Rack, just days after I blogged about it at Forthcoming Oracle Appliances. Configurations from half rack to several full racks can be combined for massive storage. Interesting that Oracle wants us to use this not only for relational data but all sorts or other stuff as well:

The Oracle Exadata Storage Expansion Rack is ideal for storing massive amounts of structured and unstructured data including historical relational data; backups of Oracle Exadata Database Machine; weblogs; documents, images, LOBs and XML files

Curt Monash about Forthcoming Oracle appliances, based on information from Oracle’s earnings call (full transcript) last week. There will be an IMDB appliance based on TimesTen for high speed analytics, and a Hadoop appliance for MapReduce jobs, targetted at data preprocessing and feeding into Oracle. It really looks like Oracle is full steam ahead on the appliance strategy, and is also starting to embrace the MapReduce and massively parallel models. All of that is likely to be announced in more details at Oracle Open World.

Good 28 page whitepaper on NoSQL for SQL Server developers, first familiarizing the reader with NoSQL, then showing what NoSQL options there are in the Microsoft and Azure stack. Also a fair bit of positioning and what are appropriate use cases for NoSQL.

A nice howto on AlwaysOn, the combined Mirroring and Clustering HA/DR solution in SQL Denali, the next version of SQL.

Reported and analysed by Tony Baer in OnStrategies Perspectives, and reported by Derrick Harris in GigaOm’s in EMC, NetApp Make It a Big Day for Big Data Star Hadoop, we learn that EMC is using the on-going EMC World conference to its potential, and is announcing that they’re growing the Database division with the decision to sell their own Hadoop distribution with value add management tools and integration. I expect to see more soon.

RainStor Database Technology Embedded Within HP Investigation Solution. I don’t know how many people have a need for investigation solutions, but there are certainly manz who have some requirements that point into the same direction, namely providing on-line (SQL) access to large amounts of relatively structured information (think logs or messages) for a long time (up to ten years or more). The announcement is also interested given that HP is probably still looking to grow its DB portfolio, so maybe there’s a new acquisition ahead if this partnership works out?

Already 3 months gone by? April 2011 Critical Patch Update Released (direct link to Database vulnerabilities). Mostly obscure components that aren’t in widespread use in the DB world, but who knows…

State of the MySQL Ecosystem

April 20th, 2011

Brian Aker wrote a good article about MySQL, State of the Ecosystem on his blog. Glad to see a key figure for MySQL be positive about the future of the ecosystem!

The 451 Group recently released a report about “How will the database incumbents respond to NoSQL and NewSQL?” Unfortunately it’s only available to their subscribers, so I can’t get the details… anyway – they followed up with a blog post What we talk about when we talk about NewSQL, which includes a pretty complete list of companies and technologies that we have to watch outside the established RDBMS vendors.

“NewSQL” is our shorthand for the various new scalable/high performance SQL database vendors. We have previously referred to these products as ‘ScalableSQL’ to differentiate them from the  incumbent relational database products. Since this implies horizontal  scalability, which is not necessarily a feature of all the products, we  adopted the term ‘NewSQL’ in the new report.

[...]

So who would be consider to be the NewSQL vendors? Like NoSQL, NewSQL  is used to describe a loosely-affiliated group of companies, but what  they have in common is the development of new relational database  products and services designed to bring the benefits of the relational  model to distributed architectures, or to improve the performance of  relational databases to the extent that horizontal scalability is no  longer a necessity.

In the first group we would include (in no particular order)  Clustrix, GenieDB, ScalArc, Schooner, VoltDB, RethinkDB, ScaleDB,  Akiban, CodeFutures, ScaleBase, Translattice, and NimbusDB, as well as  Drizzle, MySQL Cluster with NDB, and MySQL with HandlerSocket. The  latter group includes Tokutek and JustOne DB. The associated  “NewSQL-as-a-service” category includes Amazon Relational Database  Service, Microsoft SQL Azure, Xeround, Database.com and FathomDB.

I’ve been following most of them, but some of them were still news to me.

MySQL just announced a pre-release snapshot which comes with an integrated Memcached plugin accessing the InnoDB storage engine directly: NoSQL to InnoDB with Memcached

The ever-increasing performance demands of web-based services have generated significant interest in providing NoSQL access methods to MySQL. Today, MySQL is announcing the preview of the NoSQL to InnoDB via memcached. This offering provides users with the best of both worlds – maintain all of the advantages of rich SQL query language, while providing better performance for simple queries via direct access to shared data. In this preview release, memcached is implemented as a MySQL plugin daemon, accessing InnoDB directly via the native InnoDB API

I wouldn’t be surprised to see more of this kind of integration also from other DB vendors.
