MySQL & NoSQL – Best of Both Worlds. Upcoming webinar

On Thursday 22nd May I’ll be hosting a webinar explaining how you can get the best from the NoSQL world while still getting all of the benefits of a proven RDBMS. As always the webinar is free but please register here.

There’s often a lot of excitement around NoSQL Data Stores with the promise of simple access patterns, flexible schemas, scalability and High Availability. The downside can come in the form of losing ACID transactions, consistency, flexible queries and data integrity checks. What if you could have the best of both worlds?

This webinar shows how MySQL Cluster provides simultaneous SQL and native NoSQL access to your data, with a simple key-value API (Memcached), REST, JavaScript, …

MySQL Cluster 7.4.0 Labs Release

The first version of MySQL Cluster 7.4 has now been released on MySQL Labs. Note that labs loads are not suitable for production use (in fact they’re even less mature than Development Milestone Releases); their purpose is to give users a chance to see what’s in the works, try it for themselves and then provide feedback. Having read that, if you’d like to try it out then Download MySQL Cluster 7.4 from MySQL Labs.

The focus of this first Cluster 7.4 load is performance and data node restart times.

Performance

MySQL Cluster was designed from the outset to be a distributed, in-memory database and …

MySQL Cluster on Raspberry Pi - Sub-second failover

MySQL Cluster claims to achieve sub-second failover without any data loss for commited transactions. And I always wanted to show this in a demo. Now we created that demo finally. See Mark's blog and Keith's blog for setting up MySQL Cluster on RaspberryPi.
The nice thing about the RPis is that you can easily pull the plug to test failover. Ok, that is only one possible failure scenario but for sure the most obvious and more impressive than "kill -9".


That demo application is constantly using the database for storing new lines, removing old lines and reading all line data for the graphical view. There is no caching. It uses JDBC directly.
To document the setup here is the config.ini file for MySQL Cluster:

MySQL Cluster to Hadoop

How do you get data from a MySQL Cluster into Hadoop? Easy, replicate from the cluster to a stand alone MySQL instance and from there use the MySQL Hadoop Applier to HDFS.

This question came from a long time MySQL user who has jumped into the Big Data world.


Webinar: Migrating to MySQL, MariaDB Galera and/or Percona XtraDB Cluster

February 13, 2014 By Severalnines

 

Galera is slowly but surely establishing itself as a credible replacement for traditional MySQL master-slave architectures. 

The benefits are clear - a true multi-master InnoDB setup with built-in fail-over, potentially across data centers. 

But how do you migrate? Does the schema or application change? What are the limitations? Can migration be done online, without service interruption? What are the potential risks, and how to address those?

As a reminder, this webinar covered what’s new in MySQL Cluster Manager 1.3 which recently went GA.

By their very nature, clustered environments involve more efforts and resources to administer than standalone systems and this holds true for MySQL Cluster, the database designed for web-scale throughput with carrier-grade …
