DBJ – Ten Dials To Set

This month in Database Journal we start a two part article on tuning the dials of your new MySQL database.  After you install and setup your first database, you’ll need to set various parameters in your my.cnf file.  These control memory, logfiles, temp table usage, sorting, joins, and a whole lot more.  We’ll review some of the more important wants and start you on your way to more nuanced tuning of your MySQL instance.

DBJ: Optimizing the MySQL Query Cache

The MySQL Query Cache is a powerful piece of engineering that users of the popular open source database can take advantage of to speed up throughput of their applications.  MySQL’s cache operates a little bit differently from other database engines.  It does not just cache query plans, but the query data as well.  What this means is that the size and number of queries that your database manages will be variables when tuning the query cache.  We discuss all of these items in our new article at DatabaseJournal.

DBJ – Advanced MySQL Replication – Improving Performance

 Our latest article over at Database Journal is hot off the presses.  Advanced MySQL Replication – Improving Performance discusses some of the best ways to improve the performance of your MySQL slave setup.  If the slave is constantly getting further and further behind the master database, we discuss a number of techniques which may help you bring it under control.

DBJ: Reliable MySQL Replication

Part II in our series on MySQL picks up where we left off from talking about some of the challenges, and potential issues and problems that come up with MySQL replication after you have it setup and running for some time. DBJ: Fixing MySQL Replication

DBJ: Replication Pitfalls

In this month’s Database Journal article  we write about Replication Pitfalls with MySQL.

Replication is fairly straightforward to setup, however your slave databases can get out of sync, or throw errors.  We investigate some of the reasons why, and help you identify those before they come back to bite you!
