Is there a way to specify a range and list from KV?

const kv = await Deno.openKv();
kv.set(["parent", 1], "key1")
kv.set(["parent", 2], "key1")
kv.set(["parent", 3], "key1")
kv.set(["parent", 4], "key1")

const kv = await Deno.openKv();
kv.set(["parent", 1], "key1")
kv.set(["parent", 2], "key1")
kv.set(["parent", 3], "key1")
kv.set(["parent", 4], "key1")

Is it possible to retrieve only those of these that match the content of ["parent", 1~3] ?

The condition of less than or equal to 3 is also acceptable.

You want the list interface. Here's how it might look:

const entries = await Array.fromAsync(kv.list({start: ["parent", 1], end: ["parent", 3]});

const entries = await Array.fromAsync(kv.list({start: ["parent", 1], end: ["parent", 3]});

There's also the getMany interface to get multiple keys at once. https://deno.land/api@v1.41.3?s=Deno.Kv&unstable=&p=prototype.getMany

@cknight Thank you. Understood
