Dynamodb offers two types of secondary indexes − global secondary index − this index includes a partition key and sort key, which may differ from the source table. Data organization and planning for data retrieval are critical steps when designing a table.

The number data type represented by n is used to store a number. Numbers − they are limited to 38 digits, and are either positive, negative, or zero. For more information, see data types in the amazon dynamodb developer guide. The scalar types are number, string, binary, boolean, and null. By virtue of being a managed service, users are abstracted away from the underlying infrastructure and interact only with the database over a remote endpoint. Number can be positive, negative or zero.
The number data type represented by n is used to store a number. Supported data types optimistic locking using a version number with dynamodb using the aws sdk for.net object persistence model mapping arbitrary data with dynamodb using the aws sdk for.net object persistence model batch operations using the aws sdk for.net object persistence model Dynamodb supports multiple types of sets where unlike lists, all the elements within a set must be of the same type and all the elements must be also unique. But users also have a need for olap access patterns — big, analytical queries over the entire dataset to find popular items, or number of orders by day, or other insights. Number can be positive, negative or zero.
