Synchronization

We need to synchronize databases -> consistency check.

Problems:

• server have already saved the value
• other slaves have already saved the value
• all slaves correctly saved the value, but there was problems with network etc

Solution:

• Don`t give up police. If the node does not respond it will recover. Just wait for it and block user.
• When conflict appears choose a latest and become master
• Commit by getting approve from the more than half devices and get a value asked more than a half of devices
