Of the table partition key and sort key values, plus the index key values. KEYS_ONLY вЂ“ Each item in the index consists only The following is some data that could represent this. To illustrate, suppose that a game named Comet Quest isД®specially difficult, with many new users trying but failing to get a score above zero. However, the key values in a global secondary index do In a DynamoDB table, each key value must be unique. GameTitleIndex as shown in the previous diagram, the query could notДЄccess any non-key attributes other than TopScore (although the keyДЄttributes GameTitle and UserId would automatically be

Queries cannot fetch attributes from the base table. The index, DynamoDB can retrieve these projected attributes efficiently. You can project other base table attributes into the index if you want. Other scalar types, document types, and set types are Of any top-level String, Number, or BinaryДЄttributes from the base table. (partition key and sort key)-or vice versa. Simple primary key (partition key), and create a global secondary index with a composite primary key Key schema can be different from the base table schema. Set the ScanIndexForward parameter to false, the results are returned inДescending order, so the highest score is returned first.Д®very global secondary index must have a partition key, and can have an optional sort key.

The results are ordered by the sort key values, TopScore. Now you can query GameTitleIndex and easily obtain the scores for MeteorД«lasters.
