Amazon S3 or Amazon Simple Storage Service is a “simple storage service” offered by Amazon Web Services that provides object storage through a web service interface.
HVR support for Amazon S3
When using HVR, files can be captured and copied or moved to a different location. CSV and XML files can be processed for a table target. As a target, HVR can write files in multiple formats including Parquet, JSON, Avro, CSV or XML with many options to fine tune the format and define compression. HVR’s data validation feature, Data Compare, is supported through Hive external tables, or directly by reading/parsing the files.
