Amazon S3 announces feature enhancements to S3 Select. S3 Select is an 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.
Today, Amazon S3 Select works on objects stored in CSV and JSON format. Based on customer feedback, we’re happy to announce S3 Select support for 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.
