Description: Table compression is the process of reducing the size of data stored in a table within a database. This process not only saves storage space but also improves query performance by decreasing the amount of data that needs to be read from disk. Compression is achieved through techniques that eliminate redundancies and optimize data representation, which may include encoding repeated values or using specific compression algorithms. In the context of columnar storage systems, table compression is particularly relevant, as this type of storage greatly benefits from data size reduction, allowing for faster and more efficient access. Compression can be applied automatically or manually, depending on user needs and data structure. Additionally, table compression can influence cloud storage costs, as less occupied space translates to lower expenses. In summary, table compression is an essential technique in modern database management, aimed at optimizing both storage and query performance.
