Class ConnectionProperty<T>

java.lang.Object

com.google.cloud.spanner.connection.ConnectionProperty<T>

public class ConnectionProperty<T>
extends Object

ConnectionProperty is a variable for a connection. The total set of connection properties is the state of a connection, and determine the behavior of that connection. For example, a connection with a ConnectionProperty READONLY=true and AUTOCOMMIT=false will use read-only transactions by default, while a connection with READONLY=false and AUTOCOMMIT=false will use read/write transactions.

Connection properties are stored in a ConnectionState instance. ConnectionState can be transactional. That is; changes to a connection property during a transaction will be undone if the transaction is rolled back. Transactional connection state is the default for PostgreSQL-dialect databases. For GoogleSQL-dialect databases, transactional connection state is an opt-in.
