The client shows SQL statements, bound SQL statements, elapsed time, elapsed time preparing the statements, and more.
Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types. Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level. It not only supports mapping between attribute names, but also conversion between types. Many conversion scenarios are supported out of the box, but custom conversions can be specified via XML.
LibMySequoia provides an alternative library for MySQL C client library (libmysqlclient.so) to benefit from the Sequoia high availability and performance scalability clustering solution. Native MySQL client programs can use the Sequoia clustering solution without changing any line of code in the application. The benefit of this solution is that native C applications, PHP, Perl, and Python programs using the MySQL C API interface now can transparently connect to a Sequoia cluster.
