Question

In DynamoDB, how is a Global Secondary Index (GSI) stored?

A) Alongside the base table, in a separate data structure
B) In a separate physical database
C) In the same table as the base table
D) In a separate DynamoDB region

Answer 1

In DynamoDB, a Global Secondary Index (GSI) is stored alongside the base table, in a separate data structure.

Step-by-step explanation:

In DynamoDB, a Global Secondary Index (GSI) is stored alongside the base table, in a separate data structure. This means that the GSI is stored in its own separate data storage that is related to the base table, but not stored within it. It allows for efficient querying of data based on alternate keys, providing flexibility and improved performance.
