Abstract Value Members

  1. abstract def transaction[T](f: (Client) ⇒ Future[T]): Future[T]

    Execute f in a transaction.

    Execute f in a transaction.

    If f throws an exception, the transaction is rolled back. Otherwise, the transaction is committed.

    Example: 

    1. client.transaction[Foo] { c =>
 for {
    r0 <- c.query(q0)
    r1 <- c.query(q1)
    response: Foo <- buildResponse(r1, r2)
  } yield response
}
    Note

    we use a ServiceFactory that returns the same Service repeatedly to the client. This is to assure that a new MySQL connection (i.e. Service) from the connection pool (i.e., ServiceFactory) will be used for each new transaction. Only upon completion of the transaction is the connection returned to the pool for re-use.

  2. abstract def transactionWithIsolation[T](isolationLevel: IsolationLevel)(f: (Client) ⇒ Future[T]): Future[T]

    Execute f in a transaction using the given Isolation Level for this transaction only.

    Execute f in a transaction using the given Isolation Level for this transaction only. This Isolation Level overrides the session and global database settings for the transaction.

    If f throws an exception, the transaction is rolled back. Otherwise, the transaction is committed.

    Example: 

    1. client.transaction[Foo](IsolationLevel.RepeatableRead) { c =>
 for {
    r0 <- c.query(q0)
    r1 <- c.query(q1)
    response: Foo <- buildResponse(r1, r2)
  } yield response
}
