AWS doc on the pricing of AWS Redshift Spectrum says that we pay for only TB scanned. However, I still need to create a Redshift cluster and specify instance type as well as how many nodes in the cluster. So my question is: does AWS charge for the created cluster? I'd assume that a cluster with 2 dc2.8xlarge nodes would be more expensive than a cluster with 2 dc2.large nodes, even for a Redshift Spectrum cluster, but I can't find any documentation that explicitly discusses this.

CodePudding user response：

Redshift Spectrum is a querying engine service offered by AWS allowing customers to use only the computing capability of Redshift clusters on data available in S3 in different formats. This feature enables customers to add external tables to Redshift clusters and run complex read queries over them without actually loading or copying data to Redshift.

Since Redshift Spectrum is a built-in feature of Amazon Redshift, you need a redshift cluster.

To your question: Answer is yes. AWS charge for the created cluster. Yes even for redshift spectrum.
