Hey 👋 A DynamoDB Local Secondary Index (LSI) is an index that has the same partition key as the base table, but a different sort key. It is referred to as "local" in the sense that every partition of a local secondary index is scoped to a base table partition with the same partition key value.
Amazon DynamoDB provides fast access to items in a table by specifying primary key values. However, applications often require accessing data using alternate keys as well. In these cases, defining a second set of keys, a Secondary Index, is advantageous and beneficial for data access.
In this video, let’s learn about Local Secondary Index in DynamoDB, how to create one, and query data using the Index.
