Standard databases
| Quota | Limit | Adjustable | Burstable |
|---|---|---|---|
| Reads per second | 100 | Yes | Yes |
| Writes per second | 100 | Yes | Yes |
| Items | 1,000,000 | Yes | No |
| Query max nearest neighbours | 128 | Yes | No |
Capacity and burstable quotas
Burstable quotas allow you to exceed your throughput quota for a short period of time. This is useful for handling spikes in traffic. These quotas make use of token buckets to control the rate of requests.
Each database has a bucket for reads and a bucket for writes. The bucket is refilled at a rate of 100 tokens per second. Unused capacity is accumulated over time, up to a maximum of 1 minute. For example, if your quota is 100 reads per second, you can make 200 reads in 2 seconds, or 400 reads in 4 seconds, etc.
