Decoding binary protocols in python is far away from the speed one knows from C based decoders. Static typing with Cython to the rescue.

Roland opened a bug "Documentation indicates some MYSQL_FIELD->flags are deprecated which aren't."

The MySQL protocol uses the string values of ENUM- and SET-fields. To indicate that this string originated from a ENUM- or SET-column the ENUM_FLAG and SET_FLAG are used in the Column Defintion

I'm preparing the code for my MySQLConf 2010 session "MySQL Proxy meets: Memcache" where I'll present how to replicate from MySQL to memcache by using the MySQL Proxy.

Part of it will be using the semi-sync replication support for MySQL 5.5 to implement a synchronous MySQL-to-Memcache replication ...
