I published an article on the Cockroach Labs Blog: Local and distributed query processing in CockroachDB. In this article, I explain the software architecture and overall mechanisms in the SQL execution engine of CockroachDB, in the code leading up to version v1.1.

I published an article on the Cockroach Labs Blog: Modesty in Simplicity: CockroachDB’s JOIN. In this article, I explain how I designed the first (and overly simplistic) implementation of SQL joins prior to CockroachDB v1.0. Also available via the Wayback Machine.| dr knz @ work
A few months ago, I was invited to present CockroachDB to a tech consulting office in Amsterdam. The audience was welcoming and receptive. They understood, appreciated, and lauded the “flagship” features of CockroachDB: distribution, scalability, high availability, operating simplicity. Yet a question came up which I had not heard before …| dr knz @ work

Why was CockroachDB designed to be compatible with PostgreSQL? Perhaps surprisingly, the answer to this question is currently (as of early May 2018) not documented publicly …| dr knz @ work
What is faster: a local connection over a unix domain socket, or a local TCP/IP connection with TLS encryption? To a network expert, the answer seems intuitively obvious: the unix socket. But why? And by how much? Moreover, online docs and tutorials for both PostgreSQL and CockroachDB recommend—or …| dr knz @ work
