Working with DynamoDB Local and Global Indexes

In this lab, we will explore local and global secondary indexes in DynamoDB and investigate their impact on performance and capacity unit usage. An existing unindexed table is provided, and we will create a new table with local and global secondary indexes. Load the same dataset into our new table with a provided data loader. Then use a test utility to observe the performance and capacity differences when performing read operations against tables with and without indexes. **Note:** Please use the `us-east-1` region for this lab.
