(dict) --
Represents the data for an attribute.
Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself.
For more information, see Data Types in the Amazon DynamoDB Developer Guide.
S (string) --
An attribute of type String. For example:
"S": "Hello"
N (string) --
An attribute of type Number. For example:
"N": "123.45"
Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"
SS (list) --
An attribute of type String Set. For example:

"NULL": true
BOOL (boolean) --
An attribute of type Boolean. For example:
"BOOL": true
boolean
The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.
