PAD INDEX Meaning and
Definition
-
Pad index is a term commonly used in database management systems to refer to a measure of data fragmentation within an index. It is essentially a ratio that quantifies the amount of space wasted within an index due to internal fragmentation.
Specifically, pad index is calculated as the percentage of wasted space within an index page. It represents the number of unused bytes within each page that could have been utilized to store additional data. A low pad index indicates a highly efficient index with minimal wasted space, while a high pad index suggests significant fragmentations and inefficiencies.
To calculate the pad index, one needs to determine the amount of empty space within each page of the index and divide it by the total size of the page. The resulting value, typically expressed as a percentage, represents the pad index.
The pad index value is crucial in maintaining optimal performance and space utilization within a database system. A high pad index can lead to reduced query performance, slower data retrieval, and increased storage requirements. Therefore, monitoring and minimizing the pad index is important in ensuring efficient data management and system performance.
Overall, pad index is a metric that measures the wasted space within index pages, providing insights into data fragmentation and index efficiency in database management systems.
