René Cannaò	d04ee3d385	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. Old code was still present, and was possible to toggle it on and off based on PROXYSQL_STMT_V14 . Because only the new code is maintained, all references to old code are now removed, including PROXYSQL_STMT_V14	8 years ago

René Cannaò	7dbcbc3e7a	Bug fix for #1188 ... * all commands expected in Admin are serialized * Cluster get mysql servers information directly from MyHGM * Before applying MySQL servers changes, Cluster fetch again the checksum to verify it didn't change	9 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.	9 years ago
