how does connection pool work with mysql replicationDriver

I wonder how connection pool work with mysql replicationDriver. If I set connection pool to 100. How many connections would be consumed in master and slaves individually?

<property name="driverClass" value="com.mysql.jdbc.Driver"/>        
<property name="jdbcUrl" value="jdbc:mysql:replication://master,slave1,slave2,slave3/test"/> 
<property name="maxPoolSize" value="1000"/>
