  Flow Logs can be published to S3 in Parquet format: https://docs.aws.amazon.com/vpc/latest/userguide/flow-logs-s3.html#flow-logs-s3-path

  Publishing flow logs to Amazon S3 in Apache Parquet format and using Amazon Athena for analytics (D) is the most cost-effective solution. This approach minimizes storage costs due to the efficient compression of Parquet, and optimizes query performance and cost in Athena due to the reduced data size and optimized columnar storage.
