This article explains why OLAP database schema migrations are significantly more complex than OLTP migrations due to fundamental design tradeoffs: immutable columnar storage, physical ordering keys, and materialized view dependencies. The author demonstrates how optimizations that enable fast analytical reads (compression, asynchronous mutations, pre-aggregated tables) create cascading costs when schemas change.
