2021/11/23 - Amazon DynamoDB - 3 updated api methods
Changes DynamoDB PartiQL now supports ReturnConsumedCapacity, which returns capacity units consumed by PartiQL APIs if the request specified returnConsumedCapacity parameter. PartiQL APIs include ExecuteStatement, BatchExecuteStatement, and ExecuteTransaction.
{'ReturnConsumedCapacity': 'INDEXES | TOTAL | NONE'}
Response {'ConsumedCapacity': [{'CapacityUnits': 'double',
'GlobalSecondaryIndexes': {'string': {'CapacityUnits': 'double',
'ReadCapacityUnits': 'double',
'WriteCapacityUnits': 'double'}},
'LocalSecondaryIndexes': {'string': {'CapacityUnits': 'double',
'ReadCapacityUnits': 'double',
'WriteCapacityUnits': 'double'}},
'ReadCapacityUnits': 'double',
'Table': {'CapacityUnits': 'double',
'ReadCapacityUnits': 'double',
'WriteCapacityUnits': 'double'},
'TableName': 'string',
'WriteCapacityUnits': 'double'}]}
This operation allows you to perform batch reads or writes on data stored in DynamoDB, using PartiQL.
Note
The entire batch must consist of either read statements or write statements, you cannot mix both in one batch.

string
Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:
INDEXES - The response includes the aggregate ConsumedCapacity for the operation, together with ConsumedCapacity for each table and secondary index that was accessed. Note that some operations, such as GetItem and BatchGetItem , do not access any indexes at all. In these cases, specifying INDEXES will only return ConsumedCapacity information for table(s).
TOTAL - The response includes only the aggregate ConsumedCapacity for the operation.
NONE - No ConsumedCapacity details are included in the response.

This operation allows you to perform transactional reads or writes on data stored in DynamoDB, using PartiQL.
Note
The entire transaction must consist of either read statements or write statements, you cannot mix both in one transaction. The EXISTS function is an exception and can be used to check the condition of specific attributes of the item in a similar manner to ConditionCheck in the TransactWriteItems API.

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.
(string) --
BS (list) --
An attribute of type Binary Set. For example:
"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]
(bytes) --
M (dict) --
An attribute of type Map. For example:
"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}
(string) --
(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 .
L (list) --
An attribute of type List. For example:
"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N", "3.14159"}]
(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.

NULL (boolean) --
An attribute of type Null. For example:
"NULL": true
BOOL (boolean) --
An attribute of type Boolean. For example:
"BOOL": true
ConsumedCapacity (list) --
The capacity units consumed by the entire operation. The values of the list are ordered according to the ordering of the statements.
(dict) --
The capacity units consumed by an operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the request asked for it. For more information, see Provisioned Throughput in the Amazon DynamoDB Developer Guide .
TableName (string) --

CapacityUnits (float) --
The total number of capacity units consumed by the operation.
ReadCapacityUnits (float) --
The total number of read capacity units consumed by the operation.
WriteCapacityUnits (float) --
The total number of write capacity units consumed by the operation.
Table (dict) --
The amount of throughput consumed on the table affected by the operation.
ReadCapacityUnits (float) --
The total number of read capacity units consumed on a table or an index.
WriteCapacityUnits (float) --
The total number of write capacity units consumed on a table or an index.
CapacityUnits (float) --
The total number of capacity units consumed on a table or an index.
LocalSecondaryIndexes (dict) --
The amount of throughput consumed on each local index affected by the operation.
(string) --
(dict) --
Represents the amount of provisioned throughput capacity consumed on a table or an index.
ReadCapacityUnits (float) --
The total number of read capacity units consumed on a table or an index.
WriteCapacityUnits (float) --
