Free Quota
We’re offering a free quota up to the first 5 clusters created in each Organization. If you need to create the 6th cluster, you need to create a Scalable Cluster. For this, you’ll be required to provide a credit card and set a Spending Limit. But if you delete some of your previous clusters before creating the 6th, the new cluster will still have a free quota. In other words, customers can enjoy the free quota for up to 5 clusters, whether it’s Free Cluster or Scalable Cluster.
Free Quota will be issued monthly to serverless clusters that meet these qualifications. With the free quota, customers can store 5 GiB of row-based data, 5 GiB of columnar data, and consume 50 million RUs for one month.
In total, each Organization can get 25 GiB of row storage, 25 GiB of column storage, and 250M Request Units (RUs) for free per month. Customers can take advantage of this offer and optimize your operations without worrying about initial costs.
