method Deno.Kv.prototype.enqueue
Kv.prototype.enqueue(value: unknown,options?: { delay?: number; keysIfUndelivered?: KvKey[]; backoffSchedule?: number[]; },): Promise<KvCommitResult>
Add a value into the database queue to be delivered to the queue
listener via `Deno.Kv.listenQueue`.
```ts
const db = await Deno.openKv();
await db.enqueue("bar");
```
The `delay` option can be used to specify the delay (in milliseconds)
of the value delivery. The default delay is 0, which means immediate
delivery.
```ts
const db = await Deno.openKv();
await db.enqueue("bar", { delay: 60000 });
```
The `keysIfUndelivered` option can be used to specify the keys to
be set if the value is not successfully delivered to the queue
listener after several attempts. The values are set to the value of
the queued message.
The `backoffSchedule` option can be used to specify the retry policy for
failed message delivery. Each element in the array represents the number of
milliseconds to wait before retrying the delivery. For example,
`[1000, 5000, 10000]` means that a failed delivery will be retried
at most 3 times, with 1 second, 5 seconds, and 10 seconds delay
between each retry.
```ts
const db = await Deno.openKv();
await db.enqueue("bar", {
keysIfUndelivered: [["foo", "bar"]],
backoffSchedule: [1000, 5000, 10000],
});
```
