Heterogenous replication involves moving data from one database platform to another. This is a complicated endevour because datatypes, date & time formats, and a whole lot more tend to differ across platforms.

“MySQL’s JSON data type is great! But how do you index the JSON data?” I was recently presenting at the CakePHP Cakefest Conference and was asked that very question. And I had to admit I had not been able to play, er, experiment with the JSON datatype to that level. Now I have and it is fairly easy.
Greetings everyone! Let’s discuss a 3rd Party auditing solution to MySQL and how we can leverage MongoDB to make sense out of all of that data.The McAfee MySQL Audit plugin does a great job of capturing, at low level, activities within a MySQL server. It does this through some non-standard APIs which is why installing and configuring the plugin can be a bit difficult. The audit information is stored in JSON format, in a text file, by default.
Ever since MySQL replication has existed, people have dreamed of a good solution to automatically split read from write operations, sending the writes to the MySQL master and load balancing the reads over a set of MySQL slaves. While if at first it seems easy to solve, the reality is far more complex.First, the tool needs to make sure it parses and analyses correctly all the forms of SQL MySQL supports in order to sort writes from reads, something that is not as easy as it seems. Second, it needs to take into account if a session is in a transaction or not.
The following outlines an approach of identifying and improving unit tests in an OpenStack project.
You can obtain a copy of current source code for an OpenStack project at http://git.openstack.org. Active projects are categorized into openstack, openstack-dev, openstack-infra and stackforge.
NOTE: While you can find OpenStack projects on GitHub, these are just a mirror of the source repositories.
