This sample demonstrates how to use Google Cloud Spanner from Google App Engine standard Java 11 environment.

• Install the Google Cloud SDK and run:

   gcloud init

If this is your first time creating an App engine application:

   gcloud app create

• Create a Spanner instance.

• Update SPANNER_INSTANCE value in [app.yaml](src/main/appengine/app.yaml) with your instance id.

• /spanner : will run sample operations against the spanner instance in order. Individual tasks can be run using the task query parameter. See SpannerTasks for supported set of tasks. Note : by default all the spanner example operations run in order, this operation may take a while to return.

mvn clean package appengine:deploy -Dapp.deploy.projectId=<your-project-id>

To see the results of the deployed sample application, open https://PROJECT_ID.appspot.com/spanner in a web browser. Note : by default all the spanner example operations run in order, this operation may take a while to show results.
