In this presentation I describe a successful client implementation with the result of 10x performance improvements. https://ronaldbradford.com/blog/calculating-your-database-size-2009-09-25/ Fri, 25 Sep 2009 05:06:15 +0000 https://ronaldbradford.com/blog/calculating-your-database-size-2009-09-25/ I generally use the following MySQL INFORMATION_SCHEMA (I_S) query to Calculate Your MySQL Database Size . This query and most others that access the MySQL INFORMATION_SCHEMA can be very slow to execute because they are not real tables and are not governed by physical data, memory buffers and indexes for example but rather internal MySQL data structures. https://ronaldbradford.com/blog/understanding-mysql-innodb-transaction-isolation-2009-09-24/ Thu, 24 Sep 2009 06:33:04 +0000 https://ronaldbradford.com/blog/understanding-mysql-innodb-transaction-isolation-2009-09-24/ The MySQL Innodb storage engine provides ACID compliance, the ‘I’ being isolation. There are four states defined in MySQL with the tx_isolation system variable, READ-UNCOMMITTED, READ-COMMITTED, REPEATABLE-READ and SERIALIZABLE. Generally MySQL installations do not modify the default value of tx_isolation = REPEATABLE-READ, however I have seen with a number of clients the default value has been changed to READ-COMMITTED. https://ronaldbradford.com/blog/setting-up-sysbench-with-mysql-drizzle-2009-07-23/ Fri, 24 Jul 2009 00:47:16 +0000 https://ronaldbradford.com/blog/setting-up-sysbench-with-mysql-drizzle-2009-07-23/ Sysbench is a open source product that enables you to perform various system benchmarks including databases. Drizzles performs regression testing of every trunk revision with a branched version of sysbench within Drizzle Automation . https://ronaldbradford.com/blog/what-to-do-at-325am-2009-07-16/ Thu, 16 Jul 2009 07:33:37 +0000 https://ronaldbradford.com/blog/what-to-do-at-325am-2009-07-16/ Look at MySQL bug reports of course? Well actually I’m writing multiple blog posts, and I was confirming additional reference sources and links when I came across MySQL Bug #29847 – Large CPU usage of InnoDB crash recovery with a big buf pool. https://ronaldbradford.com/blog/understanding-the-various-mysql-products-variants-2009-03-13/ Fri, 13 Mar 2009 16:29:16 +0000 https://ronaldbradford.com/blog/understanding-the-various-mysql-products-variants-2009-03-13/ The MySQL marketplace today is far more complex then simply choosing between a particular version of MySQL that Sun/MySQL produces. The MySQL server product in general is released under the GNU General Public License (GPL) v2 , however you should carefully review the MySQL Legal Policies {#s0rl} as a number of exceptions and different license agreements operate for companion tools such as MySQL Cluster, MySQL client libraries and documentation for example. https://ronaldbradford.com/blog/storage-engines-at-the-mysql-conference-2008-04-08/ Tue, 08 Apr 2008 09:25:24 +0000 https://ronaldbradford.com/blog/storage-engines-at-the-mysql-conference-2008-04-08/ I’ll be following closely the progression of Storage Engines available in the MySQL Database server, well soon to be available when 5.1 gets to GA (hopefully by end of Q2 which is what we have been told).
