S3 server access logs at scale (14 minute read)
Yelp implemented object-level logging on its Amazon S3 buckets to improve data security, troubleshoot permission issues, and identify unused data for deletion, after AWS added essential features like date-based partitioning for S3 server access logs in November 2023. By converting raw logs to parquet format, Yelp reduced storage size by 85% and the number of objects by 99.99%, also using a single AWS account for querying between different accounts. The company uses access-based retention to delete unused objects. It is planning to forward S3 server access logs to Splunk for more efficient troubleshooting in the future.
