一。事务的隔离级别。
mysql的默认数据库级别是可重复读，一般的应用使用的是读已提交
http://www.zsythink.net/archives/1233/
1. Read UnCommitted(读未提交)
最低的隔离级别。一个事务可以读取另一个事务并未提交的更新结果。
2. Read Committed(读提交)
大部分数据库采用的默认隔离级别。一个事务的更新操作结果只有在该事务提交之后，另一个事务才可以的读取到同一笔数据更新后的结果。
3. Repeatable Read(重复读)
mysql的默认级别。整个事务过程中，对同一笔数据的读取结果是相同的，不管其他事务是否在对共享数据进行更新，也不管更新提交与否。
4. Serializable(序列化)
最高隔离级别。所有事务操作依次顺序执行。注意这会导致并发度下降，性能最差。通常会用其他并发级别加上相应的并发锁机制来取代它。
1.脏读。
当两个事务对数据进行操作时，事务A读取了一些数据之后，对其进行修改，但是还未提交，事务b对该数据进行读取的时候读取的是事务a修改后的数据，这个数据就是一个脏数据，如果数据a对该数据进行回滚，就会报错。
2.不可重复读
当事务A对一些数据进行读取的时候，事务B也对该数据进行了读取，并修改，当事务A再次对其进行读取的时候，就会发现数据不对，就是不可重复读。即数据不重复。
3。幻读。
在重复读的隔离级别下，数据是不能被修改的，但是可以被提交，所以当事务A对影响行数据进行读取的时候，事务b添加了一项数据，事务A再次读取的时候就会发现多了一条数据，就像出现幻觉一样。
处理方法：
1.悲观锁。
当事务处理数据的时候。默认所有的数据会被其他数据操作，所以加上锁，不开放任何权限（包括查的权限），保证所有数据都处理完再开放锁。
2。乐观锁，
当处理事务的时候，默认所有的数据不会被其他数据，再提交数据之前再进行判断库中的数据是否和一开始读的数据相同（需要再可重复读的级别下，再事务过程中，保证识别到其他操作的提交数据）。
在处理数据时，后提交的操作会时最终的数据。
二。celery
当订单提交完毕之后，用户不会马上支付，就会调用celery分配异步任务，将该任务延时一定时间，将其回滚到一开始的状态。
