mysqlnd_ms PECL extension allows read/write splitting of SQL queries on PDO layer to distribute DB and Drupal servers geographically.

The fine granularity of control over cache tables and function makes this module the ultimate tool to clear the Drupal caches.

Introduction

Cache Consistent provides a transactional aware cache backend wrapper as a means of ensuring cache consistency in setups not using the database as a cache backend. #1679344: Race condition in node_save() when not using DB for cache_field

Cache Consistent works best with the database isolation level is set to READ-COMMITTED.
It CAN be used with REPEATABLE-READ, but will in this case only mitigate the problem,
not eliminate it all together. When configured for REPEATABLE-READ, there may also
be occasionally more cache-misses.

This module tries to give an report about the current performance settings and tries to come with some recommendation related to performance extension that every Drupal site should be using to boot
