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:
“The history of mankind interests us only as it exhibits a steady gain of truth and right, in the incessant conflict which it records between the material and the moral nature.”
—Ralph Waldo Emerson (1803–1882)
“We often see malefactors, when they are led to execution, put on resolution and a contempt of death which, in truth, is nothing else but fearing to look it in the face—so that this pretended bravery may very truly be said to do the same good office to their mind that the blindfold does to their eyes.”
—François, Duc De La Rochefoucauld (1613–1680)
