/**
* Service Description: Cloud Spanner API
*
* <p>The Cloud Spanner API can be used to manage sessions and execute transactions on data stored
* in Cloud Spanner databases.
*
* <p>This class provides the ability to make remote calls to the backing service through method
* calls that map to API methods. Sample code to get started:
*
* <p>Note: close() needs to be called on the SpannerClient object to clean up resources such as
* threads. In the example above, try-with-resources is used, which automatically calls close().
*
* <p>The surface of this class includes several types of Java methods for each of the API's
* methods:
*
* <ol>
* <li>A "flattened" method. With this type of method, the fields of the request type have been
* converted into function parameters. It may be the case that not all fields are available as
* parameters, and not every API method will have a flattened method entry point.
* <li>A "request object" method. This type of method only takes one parameter, a request object,
* which must be constructed before the call. Not every API method will have a request object
* method.
* <li>A "callable" method. This type of method takes no parameters and returns an immutable API
* callable object, which can be used to initiate calls to the service.
* </ol>
*
* <p>See the individual methods for example code.
*
* <p>Many parameters require resource names to be formatted in a particular way. To assist with
* these names, this class includes a format method for each type of name, and additionally a parse
* method to extract the individual identifiers contained within names that are returned.
*
* <p>This class can be customized by passing in a custom instance of SpannerSettings to create().
* For example:
*
* <p>To customize credentials:
*
* <pre>{@code
* SpannerSettings spannerSettings =
* SpannerSettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* SpannerClient spannerClient = SpannerClient.create(spannerSettings);
* }</pre>
*
* <p>To customize the endpoint:
*
* <pre>{@code
* SpannerSettings spannerSettings = SpannerSettings.newBuilder().setEndpoint(myEndpoint).build();
* SpannerClient spannerClient = SpannerClient.create(spannerSettings);
* }</pre>
*
* <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

/**
* Creates a new session. A session can be used to perform transactions that read and/or modify
* data in a Cloud Spanner database. Sessions are meant to be reused for many consecutive
* transactions.
*
* <p>Sessions can only execute one transaction at a time. To execute multiple concurrent
* read-write/write-only transactions, create multiple sessions. Note that standalone reads and
* queries use a transaction internally, and count toward the one transaction limit.
*
* <p>Active sessions use additional server resources, so it is a good idea to delete idle and
* unneeded sessions. Aside from explicit deletes, Cloud Spanner may delete sessions for which no
* operations are sent for more than an hour. If a session is deleted, requests to it return
* `NOT_FOUND`.
*
