Could you build this?
Partial Building a reactive graph UI with basic spreadsheet math is straightforward, but integrating high-performance local-first OLAP SQL and managing complex directed acyclic execution state requires specialized data-engine engineering.
What it would actually take: The architecture pairs a client-side reactive DAG scheduler with an embedded analytical database engine like DuckDB compiled to WebAssembly. The hard parts are maintaining reactivity over columnar data structures, optimizing cache invalidation across dependent nodes during large OLAP scans, and ensuring low-latency sync. It requires deep knowledge of database internals, reactive computation graphs, and WebAssembly memory management.
