Last weekend I got to present to the MySQL Developers Room at FOSDEM in Brussels.
The subject of my presentation was NoSQL and SQL the best of both worlds…
There’s a lot of excitement around NoSQL Data Stores with the promise of simple access patterns, flexible schemas, scalability and High Availability.…
The native Memcached API for MySQL Cluster is now GA as part of MySQL Cluster 7.2
This post was first published in April 2011 when the first trial version of the Memcached API for MySQL Cluster was released; it was then up-versioned for the second MySQL Cluster 7.2 Development Milestone Release in October 2011.…
ClusterJ is part of the MySQL Cluster Connector for Java which is currently in beta as part of MySQL Cluster 7.1. It is designed to provide a high performance method for Java applications to store and access data in a MySQL Cluster database.…
The replay of the two webinars can now be accesed from mysql.com
Remember that the second part of the webinar will be on March 3rd (details below).
MySQL have been working on a new way of accessing MySQL Cluster using Java.…
This guide explores how to tune and optimize the MySQL Cluster database to handle diverse workload requirements. It discusses data access patterns and how to build distribution awareness into applications, before exploring schema and query optimization, tuning of parameters and how to get the best out of the latest innovations in hardware design.…
If you have asynchronous replication where the slave database is using MySQL Cluster then you can use the NDB API events functionality to mask/overwrite data. You might do this for example if the replica is to be used for generating reports where some of the data is sensitive and not relevant to those reports.…
A new page has been added to this site: NDB API Docs which presents the information from the header files for both the NDB API and the NDB Management API.
The material has been generated using doxygen and will be refreshed shortly after any new major, minor or maintenance release is made generally available (starting from MySQL Cluster 7.0.6).…
When adding rows to a table that’s using MySQL Cluster as the storage engine, each row is assigned to a partition where that partition is mastered by a particular data node in the Cluster. The best performance comes when all of the data required to satisfy a transaction is held within a single partition so that it can be satisfied within a single data node rather than being bounced back and forth between multiple nodes where extra latency will be introduced.…
As many people are aware, the best performance can be achieved from MySQL Cluster by using the native (C++) NDB API (rather than using SQL via a MySQL Server). What’s less well known is that you can improve the performance of your NDB-API enabled application even further by ‘batching’.…
The answer is yes – kind of.
Stored procedures are implemented in a MySQL Server and can be used regardless of the storage engine being used for a specific table. One inference from this is that they won’t work when accessing the Cluster database directly through the NDB API.…
