I'm evaluating the possibility toi scale up performance of my system dividing write operation and read operations on two separate machines. At present state my original machine named SIRIUS hosts MySQL 5.7 64bits and was configured as MASTER in the replication scheme 
the details of the Master operation are shown here:
at the beginning I decided to replicate just one db named splc_smartplc see 
Then I configured the second DB server named MIZAR as SLAVE see 
and here you can see that the replication was successfully started 
but if I add new records in the table called data_target (see the last two ones in fig.3) I cannot find them in the replicated server 
Does anybody know where is the problema and how the replication works? Looking at MySQL phpmyadmin I see that everything is ok and the replication is running fine however if I make changes to MASTER records I cannot find them replicated into the SLAVE machine as it would be. Am I wrong?
