Causal: Scaling Causal's Spreadsheet Engine from Thousands to Billions of Cells: From Maps to Arrays

Causal is a spreadsheet built for the 21st century to help people work better with numbers. Behind Causal’s innocent web UI is a complex calculation engine — an interpreter that executes formulas on an in-memory, multidimensional database. The engine sends the result from evaluating expressions like Price * Units to the browser. The engine calculates the result for each dimension such as time, product name, country e.g. what the revenue was for a single product, during February ‘22, in Australia.
