-### Single-Writer Principle

- When scaling collectors for distributed tracing with tail sampling, it's important to consider 
-the Single-Writer Principle. This principle ensures a single logical writer makes sampling decisions for a
-particular trace, avoiding conflicts that might arise from multiple collectors evaluating the same trace for 
-sampling. Techniques like using load balancing exporters in front of tail-sampling collectors can help achieve this.
