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.

Famous quotes containing the words conflict and/or resolution:
“Let’s start with the three fundamental Rules of Robotics.... We have: one, a robot may not injure a human being, or, through inaction, allow a human being to come to harm. Two, a robot must obey the orders given it by human beings except where such orders would conflict with the First Law. And three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.”
—Isaac Asimov (1920–1992)
“Unfortunately, many things have been omitted which should have been recorded in our journal; for though we made it a rule to set down all our experiences therein, yet such a resolution is very hard to keep, for the important experience rarely allows us to remember such obligations, and so indifferent things get recorded, while that is frequently neglected. It is not easy to write in a journal what interests us at any time, because to write it is not what interests us.”
—Henry David Thoreau (1817–1862)
