Partitioning is the process of dividing a single database table or data set into smaller subsets, each stored and managed independently. While users interact with the database as a whole, the underlying system accesses only the relevant partition(s), significantly improving query performance.

• Key Goals of Partitioning:
  • Enhance query performance by reducing the amount of data scanned.
  • Improve manageability by isolating data into smaller, logical subsets.
