Can I do unlimited retention using log compacted topics with Confluent Cloud?

Yes. You can set retention per topic in Confluent Cloud, including unlimited retention with log compaction. You are only limited by the amount of total storage for your cluster.

Yes, these are described in Confluent Cloud Limits and Supported Features. If you try to create more partitions than you are allowed, you will see this error:

Billing

Can I put my Confluent Cloud account on hold?

No, but you can transfer your data from Confluent Cloud before deleting your cluster. For more information, see Connecting Kafka Connect to Confluent Cloud.

How does billing work for Confluent Cloud?

All billing for Confluent Cloud is done through a credit card. If you have a Confluent Cloud Enterprise subscription, the billing setup is customized for your enterprise.

What payment methods are supported for Confluent Cloud?

Confluent Cloud only supports using a credit card for payment. With Confluent Cloud Enterprise you can use purchase order and other methods of payment.

When am I charged for using Confluent Cloud?

Pricing for Confluent Cloud is based on a consumption-based model. You only pay for the data you write, store, and read from the cluster. There is no hourly or other provisioning cost for a cluster. The monthly bill is calculated as the price per unit of usage times the total units consumed in the calendar month. For example, if write throughput was priced at $.10 per GB, and you write 500 GB of data to the cluster from January 1st to 31st, you would pay $50, plus storage and read usage charges. The credit card is charged after the end of each calendar month.

Important

To stop incurring charges after a cluster is provisioned, you can do either of the following:

  • Delete the cluster.
  • Stop all producer and consumer clients and delete all stored data.

What if I only use part of the month with Confluent Cloud?

You only pay for what you stream.

How do I change the email address used for billing on the Confluent Cloud cluster?

To change the invoice email address, contact the Confluent Cloud team. Your monthly invoice will be emailed to the email address that was provided initially during sign up for Confluent Cloud. The invoice can only be sent to a single email address.

Can I use the same email account for both Confluent Cloud Enterprise and Confluent Cloud?

No, an email account can only be in one organization at a time. If you are switching from Confluent Cloud to Confluent Cloud Enterprise or changing organizations, Confluent can move you to a different organization. If your email provider supports tagging with a plus sign (+), then you can register a new account using your existing email address with a different tag. For example, if you have an existing Confluent Cloud account using myemail@gmail.com then you could register a Confluent Cloud Enterprise account with this syntax: myemail+enterprise@gmail.com.

Where can I ask billing questions?

Use the Confluent Cloud web interface to submit a question, and the Confluent team will respond.
