Building a distributed log using S3 (under 150 lines of Go)

The post describes how to implement a durable, distributed, and highly available log using AWS S3 in less than 150 lines of Go. Key highlights include the structure of the log interface, the implementation of the Append and Read operations, handling concurrent writes with S3 conditional writes, and failover/crash recovery mechanisms. The open-source project includes code and tests, with several open issues for further improvements.
