I am looking for a few more unique examples to add to the final chapter of my upcoming book on MySQL Backup & Recovery. If you would like to share your fun experience, receive a mention and a free copy please let me know via comment. If you would like to share but not have your comment published, please note at top of your feedback.
Thanks for helping to contribute to a detailed list of what could go wrong and how to be prepared for a MySQL disaster.
Oracle has announced an open source product for the NoSQL space, the Oracle NoSQL Database. Unlike other popular products including Redis, MongoDB, Cassandra, Voldermort and many others, Oracle has set a benchmark on the features that are truly necessary for highly available data systems.
Many products in the NoSQL space have told you that consistency is not needed, eventual consistency is good enough, that transactions are not performant enough to include as a feature. No standards exists, there is no common interface for communication, or key features that products aim to meet or better. With this product, features including transactions, replicated data and failover which are built in, are features other open source NoSQL products will need to match.
Oracle NoSQL Database is a key value store, supporting a major/minor key for co-locating regularly accessed information for more consistent data retrieval. The API (built in Java) supports GET, PUT, and DEL operators. The system is designed to not have a single point of failure, and to support a node failure without impact. The replication factor is reported to enable up to 7 copies of information, which would be a feature to support cross data center management. The database driver is latency aware, so this can support load balancing operations for optimal performance.
I am excited to hear about this and looking forward to evaluating the software. I will be watching more closely how the integration of MySQL and Oracle NoSQL can be an offering for startups and Web 2.0
At Oracle Open World 2011 there has been a large number of MySQL presentations. You can download the slides of my two presentations at Explaining the MySQL Explain and Improving Performance with Better Indexes.
You can find additional supporting information for these presentations in the Effective MySQL: Optimizing SQL Statements book.
Announced on Sunday at Oracle Open World 2011 is the release of the Effective MySQL book series starting with the “Optimizing SQL Statements” title. The goal of the Effective MySQL series is a highly practical, concise and topic specific reference providing applicable knowledge to use on each page. A feedback comment provided today was “no fluff” which is great comment to re-enforce the practical nature of the series.
Details on the Effective MySQL Optimizing SQL Statements page include a sample chapter, code downloads and purchase links for print and e-books at Amazon, McGraw-Hill and Barnes & Noble.
