René Cannaò	3520dbbacc	Remove all references to PS handling before 1.4 ... Handling of prepared statements changed a lot in 1.4 , as a lot of code was rewritten.

René Cannaò	e75d474878	Added mutex in replication_lag_action()	8 years ago
René Cannaò	18f6826ef7	Added new variable to limit the number of backend connections per second ... Variable name is `mysql-throttle_connections_per_sec_to_hostgroup` . Curently it is a global variable and limits the number of new connections per hostgroup, and not per specific node. For example, if mysql-throttle_connections_per_sec_to_hostgroup=100, no more than 100 new connections can be created on any hostgroup no matter the number of servers in that hostgroup. The default is very high (1000000) thus not changing default behaviour. Tuning this variable allows to control and throttle connections spikes to the backend servers. Added also new status variable `Server_Connections_delayed`. This is a counter of how many times Hostgroup Manager didn't return a connection because the limit was reached. It is worth to note that a single client request could make multiple requests, therefore this variable counts the number of time a new connection wasn't created and not how many requests were delayed.	8 years ago
