By default, MySQL does not enforce data integrity. It allows what is called silent truncations where the result of what you INSERT or UPDATE does not represent truth. https://ronaldbradford.com/blog/the-drizzle-census-2010-04-28/ Thu, 29 Apr 2010 03:01:54 +0000 https://ronaldbradford.com/blog/the-drizzle-census-2010-04-28/ One thing I have often wondered is just how many MySQL instances exist in the world and what MySQL versions and architectures are in use. We hear of 50,000 windows downloads per day but this is misleading because MySQL is basically bundled with Linux by default or installed from various repositories. https://ronaldbradford.com/blog/how-to-find-mysql-developers-2010-03-24/ Wed, 24 Mar 2010 17:07:42 +0000 https://ronaldbradford.com/blog/how-to-find-mysql-developers-2010-03-24/ Brian wrote recently Where did all of the MySQL Developers Go? , while over in Drizzle land they have been accepted for the Google Summer of code along with many other open source projects. https://ronaldbradford.com/blog/understanding-drizzle-user-authentication-options-part-2010-03-12/ Fri, 12 Mar 2010 22:45:26 +0000 https://ronaldbradford.com/blog/understanding-drizzle-user-authentication-options-part-2010-03-12/ A key differentiator in Drizzle from it’s original MySQL roots is user based authentication. Gone is the host/user and schema/table/column model that was stored in the MyISAM based mysql.user table. https://ronaldbradford.com/blog/understanding-drizzle-authentication-options-part-1-2010-03-12/ Fri, 12 Mar 2010 21:46:49 +0000 https://ronaldbradford.com/blog/understanding-drizzle-authentication-options-part-1-2010-03-12/ A key differentiator in Drizzle from it’s original MySQL roots is user based authentication.

Any chance to swing Drizzle into a MySQL discussion is worth the research. What I found was an issue compiling and an issue running on Ubuntu 9. https://ronaldbradford.com/blog/sql-analysis-with-mysql-proxy-part-2-2009-09-03/ Thu, 03 Sep 2009 16:31:19 +0000 https://ronaldbradford.com/blog/sql-analysis-with-mysql-proxy-part-2-2009-09-03/ As I outlined in Part 1 MySQL Proxy can be one tool for performing SQL analysis. The impact with any monitoring is the art of monitoring will affect the results, in this case the performance. https://ronaldbradford.com/blog/seeking-public-data-for-benchmarks-2009-08-28/ Fri, 28 Aug 2009 18:05:29 +0000 https://ronaldbradford.com/blog/seeking-public-data-for-benchmarks-2009-08-28/ I have several side projects when time permits and one is that of benchmarking various MySQL technologies (e.g. MySQL 5.0,5.1,5.4), variants (e.g. MariaDB, Drizzle) and storage engines (e.g. Tokutek, Innodb plugin) and even other products like Tokyo Cabinet which is gaining large implementations. 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/drizzle-query-logging-2009-07-21/ Wed, 22 Jul 2009 03:49:48 +0000 https://ronaldbradford.com/blog/drizzle-query-logging-2009-07-21/ Currently Drizzle offers three (3) separate query logging plugins. These plugins offer an extensible means of gathering all or selected queries and provide the foundation for a query analyser tool. Additional filtering includes selecting queries by execution time, result size, rows processed and by any given regular expression via PCRE. https://ronaldbradford.com/blog/an-important-drizzlemysql-difference-2009-07-04/ Sat, 04 Jul 2009 04:01:11 +0000 https://ronaldbradford.com/blog/an-important-drizzlemysql-difference-2009-07-04/ There are many features that are similar in MySQL and Drizzle. There are also many that are not. I’ve previously discussed topics like Datatypes and tables , SQL_MODE and SHOW . https://ronaldbradford.com/blog/benchmarking-drizzle-with-mybenchdbddrizzle-2009-07-01/ Wed, 01 Jul 2009 17:13:37 +0000 https://ronaldbradford.com/blog/benchmarking-drizzle-with-mybenchdbddrizzle-2009-07-01/ With thanks to Patrick Galbraith and his DBD::drizzle 0.200 I am now able to test client benchmarks side by side with MySQL and Drizzle.

This feature enabled a closer compatibility to other RDBMS products. MySQL by default performs a number of silent data changes which do not help in providing a level of data integrity if you come from a more traditional background. https://ronaldbradford.com/blog/a-beginners-look-at-drizzle-datatypes-and-tables-2009-04-01/ Wed, 01 Apr 2009 22:52:31 +0000 https://ronaldbradford.com/blog/a-beginners-look-at-drizzle-datatypes-and-tables-2009-04-01/ The Drizzle database, while similar to MySQL includes a number of significant differences.
