MySQL - An Excellent Choice for a Low Cost Embedded Database

MySQL is an excellent choice for a low cost embedded database. Over 3,000 ISVs, OEMs and VARs choose MySQL for this purpose and benefit from significant cost savings when compared to using a competing database product.

The MySQL for Developers training course teaches you how to plan, design and implement applications using MySQL. Expert Oracle University instructors teach you through realistic examples, interactive instruction and hands-on exercises.

This course brings you lots of interesting facts. For example, the 'libmysqld' library is effectively a MySQL server in its own right. it is shipped as part of the standard MySQL installation. Developers with C/C++ ability can embed this library easily within their applications and it can do most of what a …

Live reconfiguration of replication topography in Connector/Java

As noted in a previous post, MySQL Connector/Java supports multi-master replication topographies as of version 5.1.27, allowing you to scale read load to slaves while directing write traffic to multi-master (or replication ring) servers.  The new release of version 5.1.28 builds upon this, allowing live management of replication host (single or multi-master) topographies.  This parallels functionality that has long existed for load-balanced connections, and enables users to add or remove hosts – or now promote slaves – for Java applications without requiring application restart.  This post aims to …

Multi-master support in MySQL Connector/Java

MySQL Connector/Java has long had support for replication-aware deployment, allowing a single logical Connection object to effectively “pool” connections to both a master and (potentially multiple) slaves.  This allowed scale-out of read load by distribution of read traffic to slaves, while routing write load to the master.  The JDBC specification provides a nice hook to know what’s read-only traffic – Connection.setReadOnly().  When a boolean value of true is passed, a ReplicationConnection will route further commands a selected slave instance, while values of false trigger routing to the master.  This is sufficient for many simple replication topographies, but not all – most notably, it …

MySQL Connector/J with Fabric Support

As Tomas announced in his keynote at MySQL Connect 2013, we are working on a brand new product called MySQL Fabric. Along with this release of MySQL Fabric, we are releasing Connector/J 5.1.26 with Fabric support on labs.mysql.com. This is an alpha-quality release that adds support for scalability features in MySQL Fabric. Sharding and read/write splitting are the initial features supported by Connector/J.
In a setup involving read/write splitting or customized sharding, we generally have to duplicate knowledge of this configuration in the client applications. This is done in connection strings specified in configuration files or directly in code. With MySQL Fabric, we can express our system-wide configuration of database servers in a way that it can be accessed by client applications. In cases where this needs to change (and it always does..), the configurations affecting client applications no longer need to be changed. The connector will …

Practical P_S: Fixing gaps in GLOBAL STATUS

Over three years ago, I noticed that there was no STATUS counter for COM_PING commands – something that is useful for ensuring proper configuration of JDBC connection pools.  Mark Leith even provided a patch, but it’s never been incorporated.  With the advances PERFORMANCE_SCHEMA makes in MySQL 5.6, that’s OK – a STATUS counter becomes somewhat redundant:

mysql> SELECT SUM(count_star) as pings
    -> FROM events_statements_summary_global_by_event_name
    -> WHERE event_name = 'statement/com/Ping';
+-------+
| pings |
+-------+
|    12 |
+-------+
1 row in set (0.02 sec)


Not only does PERFORMANCE_SCHEMA provide capabilities which mirror the STATUS counters, it really goes well beyond what’s capable there. A global counter is interesting, …
