Conflict Resolution
As the consistency achieved is eventual, the system has to resolve conflicts. There are three types of resolution:
- Read repair: The correction is done when a read finds an inconsistency. This slows down the read operation.
- Write repair: The correction takes place during a write operation, if an inconsistency has been found, slowing down the write operation.
- Asynchronous repair: The correction is not part of a read or write operation.
Concepts used for the conflict resolution are the client-specified timestamps and vector clocks.
