Introduction

This library interfaces OCaml to kdb+/q from Kx Systems, the world’s fastest time-series database.

Kdb+ mostly is an interpreter for the q language, with an associated runtime able to seamlessly store data in memory or on disk.

The interface is done through Kdb+ IPC protocol. OCaml <-> Kdb+ type conversion is done through encodings, which are OCaml values representing q's datatypes.

Functions are then provided to, through so-called encoders and decoders, convert OCaml values to corresponding q values, enabling exchanging data between Kdb+ and an OCaml program.

Dependencies

• The parsing and printing of q IPC is done with Angstrom and Faraday.

• Jane Street's Async is used (in a separate module) to handle connectivity to a Kdb+ database.
