Kx FOR DEVELOPERS

The kdb+ database, with its built-in programming language q, is limitless in its applications and proven by developers around the world, who are constantly finding new uses for it. Some focus on its streaming-analytics. Others simply use its historical database to give order to their large-scale data problems. The kdb+ database system is the foundation of Kx technology, which builds on the legacy of vector programming languages. Listening to kdb+ developers, we are constantly expanding its functionality. If you are a developer looking to learn more about kdb+/q, visit code.kx.com.

LANGUAGE

• Q is a vector-based functional paradigm programming language built into the kdb+ database.
• Further extended with qSQL, a superset of SQL, it supports time-series data types as well as joins, windowing and temporal and bitemporal aggregation and arithmetic.
• Above the time-series data types it has native support for dictionaries tables and key tables as a first class datatype, not as a plug in or after thought like other technologies.
• It is an ultrafast, compact interpreted environment, that entirely fits in the CPU's cache.
LANGUAGE

DATABASE

• Kdb+ is a jaw droppingly fast time-series columnar database with a built-in programming language called q. It is an SQL-like relational database that fully supports key value pairs. It is uniquely deployable as a streaming engine, an in-memory database and an historical database in one. Lambda/HTAP architecture is easily configurable out of the box.
• Kdb+ also has native support for time-series data types, dictionaries, tables and key tables as first class datatypes.
DATABASE

CONNECTIVITY

• The kdb+ database has an extensive array of supported connections, including ODBC [V3] and JDBC, to enable seamless connectivity to legacy database products
• Native support for web connectivity including HTTP, HTTPS, SSL/TLS, JSON, and WebSockets.
• Bi-directional communication with languages such Python and R allows you to embed your favorite libraries into q code.
• Further interfaces are available for C/C++, C#, Java, Javascript are supported along with a plethora of additional languages made available on our Github page.

SUPPORT

• There is a free 32-bit version of kdb+ available for download for non-commercial use.
• Kx has comprehensive documentation for kdb+ and q at code.kx.com, including a free version of "Q for Mortals, Version 3, An Introduction to Q Programming" by Jeffry Borror that can be found here.
• Registered users are able to participate in a listbox backed up by direct contact channels with the Kx development team. Support is also available on the public Kdb+ Personal Google Developers Group.
• Community contributions can be found on Github and there is a thriving Kx Community Meetup network in fifty countries.

Kx Technology

Kx TECHNOLOGY

The basis for Kx Technology is a unique integrated platform which includes a high-performance historical time-series columnar database called kdb+, an in-memory compute engine, and a real-time streaming processor all unified with an expressive query and programming language called q.

Designed from the start for extreme scale, and running on industry standard servers, the kdb+ database has been proven to solve complex problems faster than any of its competitors.
