How to Safely Add a New Column to a Production Database

Adding a new column can be trivial or explosive depending on the scale, the engine, and the system’s uptime requirements. In relational databases, it changes the table definition and, in some cases, rewrites data on disk. On large tables, this can lock writes or block queries. In distributed systems,
