Redesigning Goth for Enhanced Flexibility and Performance

This article by Wojtek Mach, published on March 9, 2021, discusses updates to the Goth library, a popular library used to generate OAuth2 tokens for authenticating HTTP requests to Google Cloud Storage. The redesign includes replacing persistent_term with ETS for better suitability with changing data, introducing a new HTTP client contract to allow swapping clients like Finch and HTTPoison, and addressing potential performance bottlenecks by avoiding single-process message queues. The article emphasizes explicit configuration preferences, details the new library usage, and provides code snippets for implementing these changes. Additionally, it explains the benefits of using ETS for handling heavy traffic and caching. The article concludes with a call for community feedback and contributions.
