    Parameters:
    
    cancelJournalKinesisStreamRequest -
    
    Returns:
    
    A Java Future containing the result of the CancelJournalKinesisStream operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    InvalidParameterException One or more parameters in the request aren't valid.

    Exports journal contents within a date and time range from a ledger into a specified Amazon Simple Storage Service (Amazon S3) bucket. A journal export job can write the data objects in either the text or binary representation of Amazon Ion format, or in JSON Lines text format.
    
    If the ledger with the given Name doesn't exist, then throws ResourceNotFoundException.
    
    If the ledger with the given Name is in CREATING status, then throws ResourcePreconditionNotMetException.
    
    You can initiate up to two concurrent journal export requests for each ledger. Beyond this limit, journal export requests throw LimitExceededException.
    Parameters:
    
    exportJournalToS3Request -
    
    Returns:
    
    A Java Future containing the result of the ExportJournalToS3 operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    ResourceNotFoundException The specified resource doesn't exist.
    
    ResourcePreconditionNotMetException The operation failed because a condition wasn't satisfied in advance.
    
    SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc.
    
    QldbException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.

  - listJournalKinesisStreamsForLedgerPaginator
```
default ListJournalKinesisStreamsForLedgerPublisher listJournalKinesisStreamsForLedgerPaginator(ListJournalKinesisStreamsForLedgerRequest listJournalKinesisStreamsForLedgerRequest)
```
    This is a variant of listJournalKinesisStreamsForLedger(software.amazon.awssdk.services.qldb.model.ListJournalKinesisStreamsForLedgerRequest) operation. The return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will internally handle making service calls for you.
    
    When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and so there is no guarantee that the request is valid. If there are errors in your request, you will see the failures only after you start streaming the data. The subscribe method should be called as a request to start streaming data. For more info, see Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe method will result in a new Subscription i.e., a new contract to stream data from the starting request.
    
    The following are few ways to use the response class:
    1) Using the subscribe helper method
    software.amazon.awssdk.services.qldb.paginators.ListJournalKinesisStreamsForLedgerPublisher publisher = client.listJournalKinesisStreamsForLedgerPaginator(request); CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response }); future.get();
    2) Using a custom subscriber
    software.amazon.awssdk.services.qldb.paginators.ListJournalKinesisStreamsForLedgerPublisher publisher = client.listJournalKinesisStreamsForLedgerPaginator(request); publisher.subscribe(new Subscriber<software.amazon.awssdk.services.qldb.model.ListJournalKinesisStreamsForLedgerResponse>() { public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... }; public void onNext(software.amazon.awssdk.services.qldb.model.ListJournalKinesisStreamsForLedgerResponse response) { //... }; });
    As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
    Please notice that the configuration of MaxResults won't limit the number of results you get with the paginator. It only limits the number of results in each page.
    
    Note: If you prefer to have control on service calls, use the listJournalKinesisStreamsForLedger(software.amazon.awssdk.services.qldb.model.ListJournalKinesisStreamsForLedgerRequest) operation.
    Parameters:
    
    listJournalKinesisStreamsForLedgerRequest -
    
    Returns:
    
    A custom publisher that can be subscribed to request a stream of response pages.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    InvalidParameterException One or more parameters in the request aren't valid.
    
    ResourceNotFoundException The specified resource doesn't exist.
    
    ResourcePreconditionNotMetException The operation failed because a condition wasn't satisfied in advance.
    
    SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc.

    This is a variant of listJournalS3ExportsForLedger(software.amazon.awssdk.services.qldb.model.ListJournalS3ExportsForLedgerRequest) operation. The return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will internally handle making service calls for you.
    
    When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and so there is no guarantee that the request is valid. If there are errors in your request, you will see the failures only after you start streaming the data. The subscribe method should be called as a request to start streaming data. For more info, see Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe method will result in a new Subscription i.e., a new contract to stream data from the starting request.
    
    The following are few ways to use the response class:
    1) Using the subscribe helper method
    software.amazon.awssdk.services.qldb.paginators.ListJournalS3ExportsForLedgerPublisher publisher = client.listJournalS3ExportsForLedgerPaginator(request); CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response }); future.get();
    2) Using a custom subscriber
    software.amazon.awssdk.services.qldb.paginators.ListJournalS3ExportsForLedgerPublisher publisher = client.listJournalS3ExportsForLedgerPaginator(request); publisher.subscribe(new Subscriber<software.amazon.awssdk.services.qldb.model.ListJournalS3ExportsForLedgerResponse>() { public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... }; public void onNext(software.amazon.awssdk.services.qldb.model.ListJournalS3ExportsForLedgerResponse response) { //... }; });
    As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
    Please notice that the configuration of MaxResults won't limit the number of results you get with the paginator. It only limits the number of results in each page.
    
    Note: If you prefer to have control on service calls, use the listJournalS3ExportsForLedger(software.amazon.awssdk.services.qldb.model.ListJournalS3ExportsForLedgerRequest) operation.
    Parameters:
    
    listJournalS3ExportsForLedgerRequest -
    
    Returns:
    
    A custom publisher that can be subscribed to request a stream of response pages.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    SdkException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc.
    
    QldbException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.
