Class SessionControllerClient (2.31.0)

The SessionController provides methods to manage interactive sessions.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

CreateSession(std::string const &, google::cloud::dataproc::v1::Session const &, std::string const &, Options)

Create an interactive session asynchronously.

Parameters
Name	Description
`parent`	`std::string const &` Required. The parent resource where this session will be created.
`session`	`google::cloud::dataproc::v1::Session const &` Required. The interactive session to create.
`session_id`	`std::string const &` Required. The ID to use for the session, which becomes the final component of the session's resource name. This value must be 4-63 characters. Valid characters are /[a-z][0-9]-/.

Returns

Type Description

future< StatusOr< google::cloud::dataproc::v1::Session > >

A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.dataproc.v1.Session proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

CreateSession(NoAwaitTag, std::string const &, google::cloud::dataproc::v1::Session const &, std::string const &, Options)

Create an interactive session asynchronously.

Specifying the NoAwaitTag immediately returns the [google::longrunning::Operation] that corresponds to the Long Running Operation that has been started. No polling for operation status occurs.

StreamRange< google::cloud::dataproc::v1::Session >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.dataproc.v1.Session, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.
