Data partitioning is the process of compressing data to save storage space, which indirectly improves query performance by reducing the amount of data read from disk.

Data partitioning refers to the practice of creating multiple copies of the same data across different storage locations to enhance data availability and fault tolerance, without directly impacting query performance.

Data partitioning is the method of encrypting data at rest and in transit to ensure security and privacy, which is unrelated to query performance optimization.
