Design Framework For Read-and ((hot)) Download-efficient Distributed Storage Codes - A Piggybacking

While many codes focus only on repairing "systematic" (original data) nodes, piggybacking can be used to efficiently repair parity nodes as well. Practical Impact and Implementation

The framework is engineered to meet critical requirements of modern data centers: While many codes focus only on repairing "systematic"

Unlike some advanced codes that require data to be divided into exponentially many parts, piggybacking works with a small number of "substripes," simplifying practical implementation. While many codes focus only on repairing "systematic"

This design typically reduces disk reads and network transmission by 25% to 50% during the recovery of a single-node failure. Key Design Goals While many codes focus only on repairing "systematic"
