The 1.1 and 1.0 series expose a similar feature set. Internally, the 1.1 series has been refactored to plan for future feature additions. A new configuration file format has been introduced, and limitations have been lifted. And the code quality and quality assurance has been improved.
Added the (chainable) filter concept:
use_master. Future changes are likely. Please see,
mysqlnd_ms.disable_rw_split. The configuration setting allows using the load balancing and lazy connection functionality independently of read write splitting.
function was removed, and replaced in favor of a new
user filter. You can no longer set a callback
at runtime, but instead have to configure it in the plugins
configuration file. The
user filter will pass
the same arguments to the callback as before. Therefore, you can
continue to use the same procedural function as a
callback.callback It is no longer possible to use static class
methods, or class methods of an object instance, as a callback.
Doing so will cause the function executing a statement handled
by the plugin to emit an
E_RECOVERABLE_ERROR level error, which
might look like: "
(mysqlnd_ms) Specified callback
(picker) is not a valid callback." Note: this may
halt your application.
