Practical P_S: How idle are your connections?
Employee +2 Vote Up -0Vote Down

Idle connections can cause problems both at the application side, increasing the risk of connection timeouts for applications where persistent connections are used, and the server side, where resources remain allocated to idle connections.  Any application with persistent connections, such as a JDBC application using a connection pool, will have periods where connections are idle – but it’s good to know how much time is spent idle.  Too much idle time might mean connections pools configured to …

Finding the source of problematic queries
Employee +3 Vote Up -0Vote Down

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 …

Connection attributes in MySQL 5.6
Employee +1 Vote Up -0Vote Down

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 …
