| Abstract |
MeerKAT, the 64-receptor radio telescope being built in the Karoo, South Africa, by Square Kilometre Array South Africa (SKA SA), comprises a large number of components. All components are interfaced to the Control and Monitoring (CAM) system via the Karoo Array Telescope Communication Protocol (KATCP). KATCP is used extensively for internal communications between CAM components and other subsystems. A KATCP interface exposes requests and sensors. Sampling strategies are set on sensors, ranging from several updates per second to infrequent updates. The sensor samples are of multiple types, from small integers to text fields. As the various components react to user input and sensor samples, the samples with timestamps need to be permanently stored and made available for scientists, engineers and operators to query and analyse. This paper present how the storage infrastructure (dubbed Katstore) manages the volume, velocity and variety of this data. Katstore is comprised of several stages of data collection and transportation. The stages move the data from monitoring nodes to storage node to permanent storage to offsite storage. Additional information (e.g. type, description, units) about each sensor is stored with the samples.
