Description: The ‘Logical Plan’ is an abstract representation of a query that describes data transformations in data processing systems like distributed computing frameworks. This concept is fundamental in the realm of SQL query optimization, as it allows execution engines to understand and plan how operations on data should be carried out. Essentially, the Logical Plan focuses on the operations to be performed, such as filtering, projection, and joining, without delving into the specifics of how these operations will be physically executed. This provides a layer of abstraction that facilitates optimization, as the engine can apply various strategies to enhance query performance. Furthermore, the Logical Plan is crucial for query portability, allowing queries to run in different environments without the need to rewrite code. In summary, the Logical Plan is an essential component in the architecture of data processing systems, enabling better management and optimization of SQL queries, as well as efficient execution across different platforms.
