“We went down the path of building Oracle NoSQL database because of explicit request from some of our largest Oracle Berkeley DB installations that wanted to move away from maintaining home grown sharding implementations and very much wanted an out of box technology that can replicate the robustness of what they had built “out of [...]

Many MySQL users are familiar with using slow query logs and tools such as mysqldumpslow to identify poor-performing SQL commands, and MySQL 5.6 introduces new powerful tools in PERFORMANCE_SCHEMA.  Both allow you to identify the date/time and the user account from which the command was issued, which is helpful – but if you’re using MySQL Enterprise Monitor (MEM), you can immediately identify the actual line of code responsible for the SQL command in question.  This happens to be one of my favorite and powerful features of MEM, but it’s frequently overlooked by new and experienced MEM users alike, so I’m writing the post to highlight it.

MySQL Enterprise Monitor, of course, is a commercial product that’s part of the MySQL Enterprise subscription.  But it’s freely-available under 30-day trial terms for evaluation from Oracle Software Delivery Cloud – if …

MySQL Connector/J 5.1.25 has been released, and is available in Community and Enterprise flavors on dev.mysql.com and My Oracle Support, respectively.  I’ve already noted the addition of support for connection attributes for MySQL 5.6 – 5.1.25 adds this functionality.  This release also includes a fix for Bug#68733, which caused the special light-weight ping operation to execute only against the master and currently-selected slave, rather than …

Introduced in 5.6.6, connection attributes haven’t been mentioned in any of the many overviews of new 5.6 features that I’ve seen.  You might not have even known they exist – there’s not really a “feature page” in the documentation that tells you what this is all about.  The best documentation is found in the description of the PERFORMANCE_SCHEMA tables which expose these connection attributes:

As of MySQL 5.6.6, application programs can provide key/value connection attributes to be passed to the server at connect time, using the mysql_options() and mysql_options4() C API functions. The Performance …

The recent release of the MariaDB client libraries has prompted questions about their purpose as well as provenance.  Colin Charles posted that some of these would be answered in the very near future.  I have a couple of specific questions about the MariaDB JDBC driver, which I hope will be addressed at that time.  
1.) What is really in the MariaDB JDBC driver and how exactly does it differ from the drizzle JDBC driver?  What, if any, relation is there to Connector/J code?  There is a  …
