Riak TS
Riak TS is a distributed NoSQL key/value store optimized for time series data. With TS, you can associate a number of data points with a specific point in time. TS uses discrete slices of time to co-locate data. For example, humidity and temperature readings from a meter reported during the same slice of time will be stored together on disk.
This release is uses OTP 22.
Riak TS uses tables defined according to a schema for each coherent group of data. This allows for both flexibility, in terms of collecting many different sets of data, and enough structure to make the experience of working with the collected data better.
Suppose you have a number of meters (for humidity and temperature) spread across the US. It would make sense to group your data by the state and meter number. You could even store data along multiple dimensions to ease querying.
Assuming we have a number of meters measuring humidity, temperature, and the general weather conditions, our table might look like:
CREATE TABLE BashoWeather
(
region VARCHAR NOT NULL,
state VARCHAR NOT NULL,
meter_no VARCHAR NOT NULL,
time TIMESTAMP NOT NULL,
weather VARCHAR NOT NULL,
temperature DOUBLE,
humidity DOUBLE,
PRIMARY KEY (
(region, state, QUANTUM(time, 15, 'm')),
region, state, time
)
);
Using this table we can map region, state and time (in 15 minute chunks) to weather condition, temperature, and humidity readings.

Get Started
Get started with Riak TS by downloading the TS package, then check out how to install it.
Once you have setup your first node, you will want to proceed with setting up the rest of your cluster. If you’re already familiar with Riak KV, you’ll feel right at home. If you’re new to Riak, refer to our Cluster Operations documentation.
When you’re up and running, check out our docs on querying or our supported clients.
