Foundations for Scalable Data Systems

Select an appropriate consistency model (strong, eventual, causal) for a specific feature, justifying the trade-offs between user experience, performance, and complexity.

Design a replication strategy (leader-follower vs. multi-leader) for a given workload, including a conflict resolution plan (e.g., Last-Write-Wins, CRDTs).

Apply consistent hashing with virtual nodes to distribute load or data evenly across a dynamic set of nodes.
