This document includes advanced\nCloud Firestore topics. If you're just starting out with Cloud Firestore,\nsee the [quickstart guide](/docs/firestore/enterprise/create-and-query-database)\ninstead. To make sure that your applications continue to perform well as your\ndatabase size and traffic increase, it helps to understand the mechanics of\nreads and writes in the Firestore backend. You must also understand the\ninteraction of your read and writes with the storage layer and the underlying\nconstraints that may affect performance.\n\nTo learn about some best practices before architecting your application, read\nthe following:\n\n- Understand the [high level components](https://cloud.google.com/firestore/mongodb-compatibility/docs/understand-reads-writes-scale#understand_the_high_level_components) of an API request.\n- All [writes](https://cloud.google.com/firestore/mongodb-compatibility/docs/understand-reads-writes-scale#understand_the_life_of_a_write) are handled as read-write transactions to ensure ACID properties. If a write involves multiple splits, it may require a two-phase commit process.\n- [Reads](https://cloud.google.com/firestore/mongodb-compatibility/docs/understand-reads-writes-scale#understand_the_life_of_a_read), by default, are \"strongly consistent\" and use a timestamp-based approach to avoid locks.\n- To maintain high performance, you should [avoid hotspots](https://cloud.google.com/firestore/mongodb-compatibility/docs/understand-reads-writes-scale#avoid_hotspots) by distributing operations across the key range and keeping transactions small."]]
