Using Cloud Firestore to Build Planetary Scale Apps
summary
Cloud Firestore provides real-time listeners and built‑in offline sync, supports multi-region strong consistency and multi‑document transactions, and delegates side effects to Cloud Functions. It scales to millions (examples: 20M–200M users) but enforces a 1MB document size, ~40,000 index limit, and one sustained write per document per second; billing is per read/write. Use Cloud Dataflow for high‑throughput aggregations and Cloud Run for custom backends. Expect fast bounded queries but no full‑text search, no OR, and limited multi‑range queries.
