+   Check the API at https://deno.land/api?s=Deno.Kv&unstable
+2. Deno KV has **a fixed size limit** and you might run into some issues when you are using [the conversations plugin](https://grammy.dev/plugins/conversations) whilst you're building long forms or pagination system inside a conversation. You can find out more about it in the last paragraph of the [API description](https://deno.land/api?s=Deno.Kv&unstable) but here's the short version:
+   > Keys have a maximum length of 2048 bytes after serialization.
+   > Values have a maximum length of 64 KiB after serialization.
