MongoDB Indexing | Types of Index in MongoDB

Показать описание

Indexes are the Data Structures that store a collection's data set in a form that is easy to traverse. Indexes aid in the execution of queries and help you find documents that match the query criteria without a collection scan. They provide high performance read operations for frequently used queries. Without indexes, MongoDB must scan every document of a collection to select only those documents that match the query statement. This scan is highly inefficient and requires MongoDB to process a large volume of data.
