A Spreadsheet at Google-Sheets Scale: Cell Families and Focused Recompute in lazily-rs
lazily-rs now backs a full-capacity Google Sheets workbook — 10,000,000 cells — and the part that matters isn't the build time, it's that editing one cell and reading a 1,000-cell viewport costs ~11 microseconds no matter how big the sheet is. This post walks through the two new keyed primitives that make it possible — CellMap and CellFamily — and the lazy pull-based model that recomputes only the cells you focus on, with diagrams of coarse-vs-fine-grained reactivity and the spreadsheet graph.
