Amazon S3 Select is now available in the AWS GovCloud (US) region, an isolated region designed to address specific regulatory and compliance requirements of US Government agencies, as well as contractors, educational institutions, and other US customers that run sensitive workloads in the cloud. 

S3 Select is a new Amazon S3 capability designed to pull out only the data you need from an object, which can dramatically improve the performance and reduce the cost of applications that need to access data in S3.  

Most applications have to retrieve the entire object and then filter out only the required data for further analysis. S3 Select enables applications to offload the heavy lifting of filtering and accessing data inside objects to the Amazon S3 service. By reducing the volume of data that has to be loaded and processed by your applications, S3 Select can improve the performance of most applications that frequently access data from S3 by up to 400%. 

S3 Select works on objects stored in CSV and JSON format. In addition, S3 Select supports Apache Parquet format, JSON Arrays, and BZIP2 compression for CSV and JSON objects. We are also adding support for CloudWatch Metrics for S3 Select, which lets you monitor S3 Select usage for your applications.
