Welcome to your interview.
The question is on your right: Partitioning and Sharding for Scale. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the concept of data partitioning and sharding. How do these techniques improve query performance and scalability for Full Visibility data platforms?
