Why use riak

They are extended each time a replica is updated to keep track of versions. You can also allow clients to resolve conflicts themselves if that is a better fit for your use case. If you are not interested in dealing with version conflicts on the application side, Riak Data Types offer a powerful yet easy-to-use means of storing certain types of data while allowing Riak to handle merge conflicts. These conflicts are resolved automatically by Riak using Data Type-specific algorithms inspired by research into convergent replicated data types.

When an outdated replica is returned as part of a read request, Riak will automatically update the out-of-sync replica to make it consistent. In Riak, you can set an R value for reads and a W value for writes.

These values give you control over how many replicas must respond to a request for it to succeed. This allows Riak to provide read availability even when nodes are down or laggy. The same applies for the W in writes. If this value is not specified, Riak defaults to quorum , according to which the majority of nodes must respond. There is more on replication properties elsewhere in the documentation. Riak KV 2. Riak KV. Release Notes. Download Riak KV.
