public class StreamAsyncClient
extends BaseAsyncClient
implements StreamAsync

Async client implementation for Stream service.
There are two ways to use async client: 1. Use AsyncHandler: using AsyncHandler, if the response to the call is an InputStream, like getObject Api in object storage service, developers need to process the stream in AsyncHandler, and not anywhere else, because the stream will be closed right after the AsyncHandler is invoked.
2. Use Java Future: using Java Future, developers need to close the stream after they are done with the Java Future.
Accessing the result should be done in a mutually exclusive manner, either through the Future or the AsyncHandler, but not both. If the Future is used, the caller should pass in null as the AsyncHandler. If the AsyncHandler is used, it is still safe to use the Future to determine whether or not the request was completed via Future.isDone/isCancelled.

Method Detail

builder

public static StreamAsyncClientBuilder builder()

Create a builder for this client.

Returns:

builder

consumerCommit

public Future<ConsumerCommitResponse> consumerCommit(ConsumerCommitRequest request,
                                                     AsyncHandler<ConsumerCommitRequest,ConsumerCommitResponse> handler)

Description copied from interface: StreamAsync

Provides a mechanism to manually commit offsets, if not using commit-on-get consumer semantics. This commits offsets assicated with the provided cursor, extends the timeout on each of the affected partitions, and returns an updated cursor.

Specified by:

consumerCommit in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

consumerHeartbeat

public Future<ConsumerHeartbeatResponse> consumerHeartbeat(ConsumerHeartbeatRequest request,
                                                           AsyncHandler<ConsumerHeartbeatRequest,ConsumerHeartbeatResponse> handler)

Description copied from interface: StreamAsync

Allows long-running processes to extend the timeout on partitions reserved by a consumer instance.

Specified by:

consumerHeartbeat in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

createCursor

public Future<CreateCursorResponse> createCursor(CreateCursorRequest request,
                                                 AsyncHandler<CreateCursorRequest,CreateCursorResponse> handler)

Description copied from interface: StreamAsync

Creates a cursor. Cursors are used to consume a stream, starting from a specific point in the partition and going forward from there. You can create a cursor based on an offset, a time, the trim horizon, or the most recent message in the stream. As the oldest message inside the retention period boundary, using the trim horizon effectively lets you consume all messages in the stream. A cursor based on the most recent message allows consumption of only messages that are added to the stream after you create the cursor. Cursors expire five minutes after you receive them from the service.

Specified by:

createCursor in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

createGroupCursor

public Future<CreateGroupCursorResponse> createGroupCursor(CreateGroupCursorRequest request,
                                                           AsyncHandler<CreateGroupCursorRequest,CreateGroupCursorResponse> handler)

Description copied from interface: StreamAsync

Creates a group-cursor.

Specified by:

createGroupCursor in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

getGroup

public Future<GetGroupResponse> getGroup(GetGroupRequest request,
                                         AsyncHandler<GetGroupRequest,GetGroupResponse> handler)

Description copied from interface: StreamAsync

Returns the current state of a consumer group.

Specified by:

getGroup in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

getMessages

public Future<GetMessagesResponse> getMessages(GetMessagesRequest request,
                                               AsyncHandler<GetMessagesRequest,GetMessagesResponse> handler)

Description copied from interface: StreamAsync

Returns messages from the specified stream using the specified cursor as the starting point for consumption. By default, the number of messages returned is undefined, but the service returns as many as possible. To get messages, you must first obtain a cursor using the createCursor operation. In the response, retrieve the value of the ‘opc-next-cursor’ header to pass as a parameter to get the next batch of messages in the stream.

Specified by:

getMessages in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

putMessages

public Future<PutMessagesResponse> putMessages(PutMessagesRequest request,
                                               AsyncHandler<PutMessagesRequest,PutMessagesResponse> handler)

Description copied from interface: StreamAsync

Emits messages to a stream. There’s no limit to the number of messages in a request, but the total size of a message or request must be 1 MiB or less. The service calculates the partition ID from the message key and stores messages that share a key on the same partition. If a message does not contain a key or if the key is null, the service generates a message key for you. The partition ID cannot be passed as a parameter.

Specified by:

putMessages in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.

updateGroup

public Future<UpdateGroupResponse> updateGroup(UpdateGroupRequest request,
                                               AsyncHandler<UpdateGroupRequest,UpdateGroupResponse> handler)

Description copied from interface: StreamAsync

Forcefully changes the current location of a group as a whole; reseting processing location of all consumers to a particular location in the stream.

Specified by:

updateGroup in interface StreamAsync

Parameters:

request - The request object containing the details to send

handler - The request handler to invoke upon completion, may be null.

Returns:

A Future that can be used to get the response if no AsyncHandler was provided. Note, if you provide an AsyncHandler and use the Future, some types of responses (like java.io.InputStream) may not be able to be read in both places as the underlying stream may only be consumed once.
