Former director of Industrial IoT Solutions at Kx, Hugh Hyndman, has recently posted another blog on interfacing between kdb+ and other technologies. In this article, he likens the integration of software solutions in technology to the dovetailing of wood in carpentry where, in taking the right approach, both elegance and function can be achieved. In particular, he outlines how the storage capabilities of kdb+ and the distributed clustering capabilities of Apache Spark can be cleverly combined, using their shared columnar design to achieve higher throughput and performance than via a row-based JDBC intermediary.

We would like to thank Hugh for his ongoing interest and support for Kx.
