Guided Lab: Querying a Local Secondary Index

Tutorials-Dojo

Description

A Local Secondary Index (LSI) in DynamoDB is an index that has the same partition key as the base table, but a different sort key. It’s “local” in the sense that every partition of a local secondary index is scoped to a base table partition that has the same partition key value.

One important thing to note about LSIs is that they must be specified at the time of table creation. You cannot add a local secondary index to an existing table. This is a key difference from Global Secondary Index.
