The size of keys and values have different limits depending on the Durable Object storage backend you are using. Refer to either:
- [SQLite-backed Durable Object limits](/durable-objects/platform/limits/#sqlite-backed-durable-objects-general-limits)
- [KV-backed Durable Object limits](/durable-objects/platform/limits/#key-value-backed-durable-objects-general-limits).<br/><br/>

- <code>put(entries <Type text="Object" />, options <Type text="Object" />{" "}<MetaInfo text="optional" />)</code>: <Type text="Promise" />

- Takes an Object and stores each of its keys and values to storage.
- Each value can be any type supported by the [structured clone algorithm](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm), which is true of most types.
- Supports up to 128 key-value pairs at a time. Each key is limited to a maximum size of 2,048 bytes and each value is limited to 128 KiB (131,072 bytes).
- Supports up to 128 key-value pairs at a time. The size of keys and values have different limits depending on the flavor of Durable Object you are using. Refer to either:
