Closes all connections to Google Cloud Spanner that have been opened by this driver during the lifetime of this application . You should call this method when you want to shutdown your application as this frees up all connections and sessions to Google Cloud Spanner . Failure to do so will keep sessions open server side and can eventually lead to resource exhaustion . Any open JDBC connection to Cloud Spanner opened by this driver will also be closed by this method . This method is also called automatically in a shutdown hook when the JVM is stopped orderly .
