Ever tried to migrate a terabyte of data while your production system is running at full capacity? In these times of big data, a terabyte might not sound like much – until you need to move it on a live system with strict memory and CPU constraints, zero downtime tolerance, and users depending on every millisecond of performance.
This session tells the story of a real-world data migration challenge that pushed .NET's capabilities to their limits. Faced with the daunting task of migrating 1TB of critical in-process data without impacting system performance, we turned to an elegant combination of Task Parallel Library (TPL) and System.Threading.Channels to orchestrate a solution that was both performant and reliable.
