What is Upstash?

Upstash is a serverless database service compatible with Redis® API.

What does it mean Serverless Database?

You do not have to manage and provision servers. You do not deal with configuring or maintaining any server. You just use the service and pay what you use. If you are not using, you should not be paying.

What are the use cases?

Upstash works for all the common usecases for Redis®. You can use Upstash in your serverless stack. In addition, you can use Upstash as storage (or caching) for your serverless functions. See Use Cases for more.

Most of them. See Redis® API Compatibility for the list of supported commands.

Upstash is serverless. With Redis Labs or Compose.io, you always pay a lot when your data size is big but your traffic is low. In Upstash, the pricing is based on per request. See Compare for more info.

Do you persist data?

Yes, by default we write data to the disk. So in case of a failure you should not lose any data. For a better high availability, enable Multi Zone replication.

We support replication in Premium type database. We do not support sharding yet.

I have database with 10GB data, I pay nothing if I do not use it. Is that correct?

You only pay for the disk storage cost that is $0.25 per GB. For your case, you will pay $2.5 monthly.

What happens when I exceed the request limit on Free Database (10.000 requests per day)?

The exceeding commands return exception.
