The output can be used by other services for visualization, storage, or various analytics purposes. The source data in S3 can be in any of the following structured, semi-structured, or unstructured data formats: XML, JSON, CSV/TSV, AVRO, Parquet, or ORC (as well as others). CloudTrail, ELB logs, and VPC flow logs can also be stored in S3 and analyzed by Athena.
