/**

* @file rw_select_insert.cpp Checks changes of COM_SELECT and COM_INSERT after queris to check if RWSplit
|
||||
* sends queries to master or to slave depending on if it is write or read only query
|
||||
* - connect to RWSplit, create table
|
||||
* - execute SELECT using RWSplit
|
||||
* - check COM_SELECT and COM_INSERT change on all nodes
|
||||
* - execute INSERT using RWSplit
|
||||
* - check COM_SELECT and COM_INSERT change on all nodes
|
||||
* - repeat previous steps one more time (now SELECT extracts real date, in the first case table was empty)
|
||||
* - execute SELECT 100 times, check COM_SELECT and COM_INSERT after every query (tolerate 2*N+1 queries)
|
||||
* - execute INSERT 100 times, check COM_SELECT and COM_INSERT after every query (tolerate 2*N+1 queries)
