To perform a basic sort in DynamoDB, you can use the SortKey attribute in a table. Here are the steps to do a basic sort in DynamoDB:

1. Create a table with a Partition Key and a Sort Key: When creating a table in DynamoDB, define a Partition Key and a Sort Key. The Partition Key is used to distribute items across multiple partitions for scalability. The Sort Key is used to order items within a partition.
2. Insert items with different values for the Sort Key: When inserting items into the table, make sure to include different values for the Sort Key. Items with the same Partition Key will be stored together in the same partition and will be sorted based on the Sort Key value.
3. Query the table using both the Partition Key and Sort Key: To retrieve sorted items from the table, use the Query operation with the Partition Key and provide a range of Sort Key values to retrieve a subset of items in sorted order. You can also apply filter expressions to further refine the results.

By following these steps, you can perform a basic sort in DynamoDB by utilizing the Sort Key attribute in a table.
