Each Realtime Database instance has LIMITS on the number of write operations per second. For small writes, this LIMIT is approximately 1000 write operations per second. In addition, each database instance has a cap on the number of simultaneous database connections.

Our default limits are large ENOUGH for most applications. If you are building an APP that REQUIRES additional scale, we recommend tracking your usage over time and contacting us if you get near these limits. In some cases, we may need to shard your application across multiple database instances for added scale.
