The Internet of Things (IoT) is characterised by sensors, software, and other technologies that connect and share data with other devices and systems over the Internet. It is a complex interaction of languages, systems, and protocols where tapping its value depends on interoperability to process and extract value from the vast amounts of data being generated.
MQTT is a messaging protocol for IoT. It was designed as an extremely lightweight publish/subscribe messaging transport and is particularly useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
KX has released an MQTT interface (documented on code.kx.com with source code available on Github) and in this paper, Rian uses a Raspberry Pi to illustrate how kdb+, along with pre-existing Python and JSON functionality, can be used for capturing, storing and querying IoT data.
