Riak is a key/value data store written in Erlang. It implements principles from Amazon's Dynamo paper.

Riak is a NoSQL database implementing the principles from Amazon's Dynamo paper. Riak is designed to deliver maximum data availability by distributing data across multiple servers. As long as your Riak client can reach one Riak server, it should be able to write data.

While Riak is typically known as an eventually consistent system, beginning with version 2.0 it can be used either as an eventually or strongly consistent system, and these two approaches can be mixed and matched in a single cluster.

Upsert in Riak TS

Is there any way to upsert in RIAK TS, like one can do in Mongodb? Do I have to check if a key exists and if it does, manually overwrite it? Or can I assume that an insert will overwrite any existing key?
