Design a Key Value Store

Design a high-performance, distributed key-value store system that offers fast data access, scalability, and high availability. The system should support operations such as set, get, delete, and conditional updates with minimal latency. Features should include data replication across multiple nodes to ensure fault tolerance, partitioning to distribute data evenly across the cluster, and persistence options to safeguard data. The system must efficiently handle high volumes of read/write operations and provide consistency and durability guarantees. Examples include, Redis or DynamoDB.
