Reconstructing a streaming session was a tedious and time consuming process that involved tracing all interactions (requests) between the Netflix app, our Content Delivery Network (CDN), and backend microservices. A second job taps the data feed from the first job, does tail sampling of data and writes traces to the storage system.

Estimates vary, but most reports put the average cost of unplanned database downtime at approximately $300,000 to $500,000 per hour, or $5,000 to $8,000 per minute. With so much at stake, database high availability and fault tolerance have become must-have items, but many companies just aren’t certain which one they must have.
