What is DynamoDB indexing and how does it work?
DynamoDB indexing allows you to query your data efficiently. It uses primary keys and secondary indexes to retrieve items.
Can you explain the difference between a primary key and a secondary index?
A primary key uniquely identifies each item in a table, while a secondary index allows for querying on non-primary key attributes.
How do I create a secondary index in DynamoDB?
You can create a secondary index by specifying it in the table creation process or by updating an existing table.
What are the performance implications of using secondary indexes?
Secondary indexes can improve query performance but may increase write costs and storage requirements.
