Conflict Resolution:
Go
For reasons explained in the Introduction to conflict resolution, we strongly recommend adopting a conflict resolution strategy that requires applications to resolve siblings according to usecase-specific criteria. Here, we’ll provide a brief guide to conflict resolution using the official Riak Go client.
How the Go Client Handles Conflict Resolution
In the Riak Go client, it is possible that the result of a fetch will return an array of sibling objects. If there are no siblings, that property will return an array with one value in it.
Example: creating object with siblings
So what happens if the length of Values is greater than 1, as in the case
above?
In order to resolve siblings, you need to either: fetch, update, and store a
canonical value; or choose a sibling from the Values slice and store that as
the canonical value.
Basic Conflict Resolution Example
In this example, you will ignore the contents of the Values slice and will
fetch, update and store the definitive value.
Example: resolving siblings via store
Choosing a value from Values
This example shows a basic sibling resolution strategy in which the first sibling is chosen as the canonical value.
Example: resolving siblings using the first value
Using ConflictResolver
This example shows a basic sibling resolution strategy in which the first sibling is chosen as the canonical value via a conflict resolution type.
