What is Erasure Coding?

Erasure coding is a data protection method used in system design to ensure data reliability and availability. It works by dividing data into smaller chunks and then creating additional pieces of data called parity data using mathematical algorithms. This allows the system to recover the original data even if some chunks are lost or corrupted....
