Deduplication
Deduplication is a data processing technique that identifies and eliminates duplicate copies of repeating data to optimize storage, improve performance, and ensure data integrity. It is widely used in storage systems, databases, and data pipelines to reduce redundancy and manage resources efficiently. The process can occur at various levels, such as file-level, block-level, or byte-level, depending on the implementation.
Developers should learn deduplication when working with large-scale data storage, backup systems, or data-intensive applications to minimize storage costs and enhance data retrieval speeds. It is crucial in scenarios like cloud storage, database management, and data warehousing, where duplicate data can lead to inefficiencies and increased operational expenses. Understanding deduplication helps in designing systems that handle data more effectively and scale economically.
