  title: Amazon DynamoDB Backups Queries API
  description: Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB uses a JSON-based wire protocol with target-specific headers in an RPC style. The API exposes operations for creating and managing tables, reading and writing items, and executing queries and scans. All requests are authenticated via AWS Signature Version 4 and use the X-Amz-Target header to specify the operation.

      summary: Amazon Dynamodb Query Items by Primary Key
      description: Finds items based on primary key values. You can query a table, a local secondary index, or a global secondary index. You must provide a specific value for the partition key. You can optionally narrow the scope of the query using a sort key condition and filter expression. Query results are always sorted by the sort key value.

      description: Returns one or more items and item attributes by accessing every item in a table or a secondary index. Scan operations proceed sequentially. For faster performance on a large table or secondary index, you can request a parallel scan by specifying the Segment and TotalSegments parameters. A filter expression can be applied to narrow the results.
