[HyperDB] Splitting READs and WRITEs

[J M]

i have this configuration:

add_db_server('global',0,'slave1',1,0,'192.168.136.141:3306','
192.168.136.141:3306',wordpress,user,user);
// Slave DB

add_db_server('global',0,'master1',2,1,'192.168.136.70:3306','
192.168.136.70:3306',wordpress,user,user);
// Master DB



-- enabled logging in mysql but some reason not select's are being thrown to
the "slave1" node.. all SQL are being executed on "master"

any ideas why? did i miss something?
