Kaip apskaičiuoti Index Size

Kas yra Index Size?

A database index size estimator calculates how much disk space database indexes will consume based on the number of rows, indexed column sizes, and index type. Indexes speed up queries but consume 20–100% of the table size in additional storage; over-indexing slows write performance.
