How Goldcast scaled event orchestration to millions using Temporal

What this post added

This post details Goldcast's implementation of Temporal Workflows for two key use cases: 1) Reliable email delivery at scale, involving breaking down large recipient lists into parallel batches, with a focus on resilient error handling and performance optimizations. 2) Event duplication orchestration using a two-phase workflow design: a synchronous, rollback-safe main workflow for core transactional operations and an asynchronous workflow for background processing of non-critical tasks. The post provides code examples and metrics demonstrating improved success rates and reduced processing times.
