queryWriteStatus(QueryWriteStatusRequest request, StreamObserver<QueryWriteStatusResponse> responseObserver)
public void queryWriteStatus(QueryWriteStatusRequest request, StreamObserver<QueryWriteStatusResponse> responseObserver)
Determines the persisted_size for an object that is being written, which
can then be used as the write_offset for the next Write() call.
If the object does not exist (i.e., the object has been deleted, or the
first Write() has not yet reached the service), this method returns the
error NOT_FOUND.
The client may call QueryWriteStatus() at any time to determine how
much data has been processed for this object. This is useful if the
client is buffering data and needs to know which data can be safely
evicted. For any sequence of QueryWriteStatus() calls for a given
object name, the sequence of returned persisted_size values will be
non-decreasing.
readObject(ReadObjectRequest request, StreamObserver<ReadObjectResponse> responseObserver)
public void readObject(ReadObjectRequest request, StreamObserver<ReadObjectResponse> responseObserver)
Parameters
startResumableWrite(StartResumableWriteRequest request, StreamObserver<StartResumableWriteResponse> responseObserver)
public void startResumableWrite(StartResumableWriteRequest request, StreamObserver<StartResumableWriteResponse> responseObserver)
Starts a resumable write. How long the write operation remains valid, and
what happens when the write operation becomes invalid, are
service-dependent.
writeObject(StreamObserver<WriteObjectResponse> responseObserver)
public StreamObserver<WriteObjectRequest> writeObject(StreamObserver<WriteObjectResponse> responseObserver)
Stores a new object and metadata.
An object can be written either in a single message stream or in a
resumable sequence of message streams. To write using a single stream,
the client should include in the first message of the stream an
WriteObjectSpec describing the destination bucket, object, and any
preconditions. Additionally, the final message must set 'finish_write' to
true, or else it is an error.
For a resumable write, the client should instead call
StartResumableWrite() and provide that method an WriteObjectSpec.
They should then attach the returned upload_id to the first message of
each following call to Create. If there is an error or the connection is
broken during the resumable Create(), the client should check the status
of the Create() by calling QueryWriteStatus() and continue writing from
the returned persisted_size. This may be less than the amount of data the
client previously sent.
The service will not view the object as complete until the client has
sent a WriteObjectRequest with finish_write set to true. Sending any
requests on a stream after sending a request with finish_write set to
true will cause an error. The client should check the response it
receives to determine how much data the service was able to commit and
whether the service views the object as complete.
