DynamoDbAsyncTable (AWS Java SDK :: DynamoDB :: Enhanced Client 2.17.13 API)

Type Parameters:

T - The type of the modelled object.

All Superinterfaces:

MappedTableResource<T>

All Known Implementing Classes:

DefaultDynamoDbAsyncTable
```
public interface DynamoDbAsyncTable<T>
extends MappedTableResource<T>
```
Asynchronous interface for running commands against an object that is linked to a specific DynamoDb table resource and therefore knows how to map records from that table into a modelled object.
By default, all command methods throw an UnsupportedOperationException to prevent interface extensions from breaking implementing classes.

DynamoDbAsyncIndex<T> index(String indexName)
```
    Returns a mapped index that can be used to execute commands against a secondary index belonging to the table being mapped by this object. Note that only a subset of the commands that work against a table will work against a secondary index.
    
    Parameters:

  - createTable
```
default CompletableFuture<Void> createTable(CreateTableEnhancedRequest request)
```
    Creates a new table in DynamoDb with the name and schema already defined for this DynamoDbTable together with additional parameters specified in the supplied request object, CreateTableEnhancedRequest.
    Use DynamoDbEnhancedClient.table(String, TableSchema) to define the mapped table resource.
    This operation calls the low-level DynamoDB API CreateTable operation. Note that this is an asynchronous operation and that the table may not immediately be available for writes and reads. Consult the CreateTable documentation for further details and constraints.
    Example:
```
 

 ProvisionedThroughput provisionedThroughput = ProvisionedThroughput.builder()
                                                                    .readCapacityUnits(50L)
                                                                    .writeCapacityUnits(50L)
                                                                    .build();
 mappedTable.createTable(CreateTableEnhancedRequest.builder()
                                                   .provisionedThroughput(provisionedThroughput)
                                                   .build())

  - createTable
```
default CompletableFuture<Void> createTable(Consumer<CreateTableEnhancedRequest.Builder> requestConsumer)
```
    Creates a new table in DynamoDb with the name and schema already defined for this DynamoDbTable together with additional parameters specified in the supplied request object, CreateTableEnhancedRequest.

    This operation calls the low-level DynamoDB API CreateTable operation. Note that this is an asynchronous operation and that the table may not immediately be available for writes and reads. Consult the CreateTable documentation for further details and constraints.
    Note: This is a convenience method that creates an instance of the request builder avoiding the need to create one manually via CreateTableEnhancedRequest.builder().
    Example:

                                                                    .build();
 mappedTable.createTable(r -> r.provisionedThroughput(provisionedThroughput)).join();
 
 
```
    Parameters:

Currently, there is no mechanism supported within this library to wait for/check the status of a created table. You must provide this functionality yourself. Consult the CreateTable documentation for further details and constraints.

default PagePublisher<T> query(Consumer<QueryEnhancedRequest.Builder> requestConsumer)
```
    Executes a query against the primary index of the table using a QueryConditional expression to retrieve a list of items matching the given conditions.
    Note: This is a convenience method that creates an instance of the request builder avoiding the need to create one manually via QueryEnhancedRequest.builder().

```
    Parameters:

```
default PagePublisher<T> query(QueryConditional queryConditional)
```
    Executes a query against the primary index of the table using a QueryConditional expression to retrieve a list of items matching the given conditions.
    The result is accessed through iterable pages (see Page) in an interactive way; each time a result page is retrieved, a query call is made to DynamoDb to get those entries.

You can use DynamoDbAsyncWaiter.waitUntilTableNotExists(software.amazon.awssdk.services.dynamodb.model.DescribeTableRequest) in the underlying client.
    Example:
```
 

 mappedTable.deleteTable().join();
 
 
```
    Returns:
    
    a CompletableFuture of Void.
