I am glad to announce the availability of the first alpha version of PDO_MYSQLND. PDO_MYSQLND is a PHP PDO driver for MySQL based on the MySQL native driver. PDO_MYSQLND 1.0.2-alpha is available for download on http://downloads.mysql.com/forge/pdo_mysqlnd_preview.

Updates include fixes for return values, patches for memory leaks, more code coverage and some "very promising results" running on a set of dedicated testing machines.

59 - that is the number of statistics collected by mysqlnd. When I started writing this blog post, I hoped it would be easy going describing them. But it wasn't. Some ten days ago, we've had 51 statistics and near zero tests for them. Now we have 59 statistics. And, in a certain way, every figure is a tuning screw in the hand of one who knows what they do.

The list of stats presented include functionality for:

• buffered_sets, ps_buffered_sets
• rows_buffered_from_client_normal, rows_buffered_from_client_ps
• rows_fetched_from_client_ps_buffered
• unbuffered_sets, ps_unbuffered_sets
• rows_fetched_from_client_ps_unbuffered
• flushed_normal_sets, flushed_ps_sets

Check out the rest of the post for the numbers and results (as well as some images showing the difference between buffered and unbuffered results).
