Description: Projection Encoding is a method used in data warehousing solutions to compress data, thereby optimizing storage and improving query performance. This approach is based on the idea that data can be represented more efficiently by storing only the necessary columns for a specific query, rather than the entire table. By applying this technique, data warehousing systems can significantly reduce the size of stored data, which in turn lowers storage costs and enhances data access speed. Projection Encoding allows users to define which columns should be included in the projection, facilitating customization and query optimization. Additionally, this method is particularly useful in large-scale data analysis environments, where storage efficiency and quick information retrieval are crucial. In summary, Projection Encoding is a powerful tool that helps maximize storage efficiency and query performance by enabling effective data compression.
