Description

数据事务处理方法、装置以及电子设备
本申请要求2017年08月25日递交的申请号为201710738319.8、发明名称为“数据事务处理方法、装置以及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机技术领域，具体涉及一种数据事务处理方法。本申请同时涉及一种数据事务处理装置，另一种数据事务处理方法以及装置，以及两种电子设备。
背景技术
数据库事务是数据库的基本工作单元，让数据库从一个一致的状态转移到另一个一致的状态，数据库事务允许对数据库中不同的数据项同时进行写操作，这些操作要么全部成功执行，要么全部不执行，即使系统发生故障，未执行完成的数据库事务依然可以正确恢复，而数据库事务之间可以在不同程度上进行隔离，以保证数据的正确性。
目前，在分布式数据库中，数据分布在不同的机器上，一个数据库事务往往需要访问多台机器，为了保证事务的原子性，需要确保参与数据库事务的机器相互协作，这个过程非常复杂并且对系统的性能有很大的影响，所以大多数分布式数据库并不支持事务。以一个典型的业务场景邮箱业务为例，每封邮件有以下属性：发件人、时间、状态(已读/未读)等，当邮箱账号收到新邮件时，需要进行存储新邮件的内容、修改收件箱列表、未读邮件数等操作，为了满足不同查询条件排序的需求，业务还会对原始数据建立不同的索引，每次写入一份原始数据和多份索引数据，这些写入操作需要在一个事务中完成，但在数据库不支持多行事务的场景下，需要业务来实现事务的各项特性，参照附图1所示的业务层写入逻辑的示意图，根据读出来的数据对原有数据进行更新，并且每笔数据写入成功后再写下一笔数据，直到所有数据都成功写入。但这种方式需要考虑每次写入失败的回退处理，并且在回退删除已经写入的数据时需要进行无限重试，业务逻辑较为复杂；此外，如果业务程序发生宕机，写入数据无法进行回退，因此无法满足事务性需求。

具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其他方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施的限制。
本申请提供一种数据事务处理方法，本申请还提供一种数据事务处理装置，另一种数据事务处理方法以及装置，以及两种电子设备。以下分别结合本申请提供的实施例的附图逐一进行详细说明，并且对方法的各个步骤进行说明。
本申请提供的一种数据事务处理方法实施例如下：
参照附图2，其示出了本申请提供的一种数据库事务处理场景的示意图。
步骤1，接收客户端发送的在目标数据分区进行数据操作的申请请求。
本步骤是后续对目标数据分区进行数据操作的基础，通过所述客户端发送的在目标数据分区进行数据操作的申请请求，才可能获得操作所述目标数据分区的数据操作的权限。本申请实施例以数据库事务为例进行说明，比如构建在分布式系统之上的分布式数据库(如NoSQL数据库)的数据库事务。所述分布式系统是指通过网络将物理上分散的多个数据存储单元连接组成的逻辑统一的数据库，在所述分布式数据库的基础上基于数据分片和负载均衡，能够使所述分布式数据库在规模上实现无缝扩展。
所述目标数据分区，是指所述客户端期望操作的数据集合，本实施例中，所述目标数据分区是指分区当中的分区键，所述分区是指数据存储中负载均衡的基本调度单位，通过分区实现数据存储的水平扩展，保证性能和可用性。具体而言，数据库中包含的数据表的主键由数据表中的至少一个主键列组成，所述分区键是指所述数据表的第一个主键列组成的单分区键，在一个分区当中，可能包含多个分区键，并且这些分区键之间不会有重合。除此之外，在具体实施时，所述目标数据分区还可以是所述数据表中所述分区键之外的主键列或者多个主键列的集合，比如所述目标数据分区还可以是所述数据表的第一个主键列之外的其他任意一个主键列组成的单分区键，或者，所述目标数据分区还可以是所述数据表的多个主键列组成的联合分区键，或者所述目标数据分区还可以是多个分区键组成的联合分区键，本实施例对此不作限定。所述客户端在申请请求中嵌入目标数据分区的分区键，当接收到来自所述客户端的申请请求，获得所述申请请求中的分区键，进而确定所述客户端期望操作的数据集合。所述数据操作，是指对所述分区键下数据的具体操作，例如增加一行数据、删除一行数据、修改某行或某些行数据中的某个或某些值、读取某个或某些数据等。
本步骤中，接收所述客户端发送的在分区键下进行数据操作的申请请求，即申请分区键的数据库事务。例如，如附图2所示，接收业务1对应的客户端发送的申请分区键PK0为0的数据库事务。
步骤2，根据所述申请请求创建对应的数据事务，并为所述数据事务分配事务标识。
上述步骤1接收所述客户端发送的在分区键下进行数据操作的申请请求，即申请分区键的数据库事务，本步骤根据所述申请请求创建对应的数据库事务，并为所述数据库事务分配事务标识。
所述事务标识是为数据库事务分配的识别码，一个数据库事务有且仅有一个事务标识，并且每个数据库事务的事务标识都不相同。更具体地说，所述事务标识可以采用字符串的形式，也可以采用数字的形式。
例如，如附图2所示，接收到业务1对应的客户端发送的申请分区键PK0为0的数据库事务之后，创建数据库事务3，并为当前新创建的数据库事务3分配对应的事务ID(事务标识)。
本步骤中为所述数据库事务分配事务标识，为后续所述客户端修改所述数据库事务提供基础，由于服务端同时分配不同的数据库事务给若干个业务对应的客户端，因此，需要根据所述事务标识确定所述客户端所要修改的具体的数据库事务。同时，由于服务端同时分配不同的数据库事务给若干个业务对应的客户端，因此，在为所述数据库事务分配事务标识的同时，将所述数据库事务对应的所述分区键锁定，即不允许所述数据库事务之外的其他数据库事务对所述分区键下的数据进行数据操作。例如，如附图2所示，当业务1对应的客户端发送的申请分区键PK0为0的数据库事务3被锁定之后，业务2对应的客户端申请分区键PK0为0的数据库事务时，申请失败。
在实际应用中，可针对所述分区键设置相应的状态，包括锁定状态和未锁定状态，一旦接收到的所述申请请求为在当前分区键下进行数据操作的申请请求，当前分区键的状态被更新为锁定状态；若尚未接收到在当前分区键下进行数据操作的申请请求，则当前分区键的状态保持为未锁定状态。
基于此，在具体实施时，在本步骤据所述申请请求创建对应的数据库事务，并为所述数据库事务分配事务标识之前，需要判断所述客户端申请的分区键是否被锁定，具体通过判断所述分区键的状态是否为未锁定状态来判断所述分区键是否被锁定，如果所述分区键已经被锁定，则针对上述步骤1中所述客户端发送的在所述分区键下进行数据操作的申请请求，做出申请失败的回应，并且不再创建数据库事务以及分配事务标识；如 果所述分区键未被锁定，则执行本步骤，根据所述申请请求创建对应的数据库事务，并为所述数据库事务分配事务标识。
步骤3，将分配给所述数据事务的事务标识返回给所述客户端。
上述步骤2根据所述申请请求创建对应的数据库事务，并为所述数据库事务分配事务标识，本步骤中，将上述步骤2为所述数据库事务分配的事务标识返回给所述客户端。例如，如附图2所示，将分配给数据库事务3的事务ID返回给业务1对应的客户端，业务1对应的客户端接收到数据库事务3的事务ID，表示申请成功。
此外，将所述数据库事务分配的事务标识返回给所述客户端之后，还可以启动超时检测机制，所述超时检测机制具体通过判断在一定的时间阈值范围内是否接收到所述客户端发送的动作指令，即所述时间阈值范围内是否接收到下述步骤4中所述客户端发送的针对所述数据事务进行处理的动作指令，如果没有，则触发超时，销毁所述数据库事务，回收所述事务标识，也就是说，所述数据库事务标识失效，其所对应的事务标识亦失效。在具体实施时，所述时间阈值范围可根据实际应用场景灵活设定。
步骤4，根据所述客户端提交的携带所述事务标识的数据操作，基于所述目标数据分区执行所述数据操作。
本步骤根据所述客户端提交的携带所述事务标识的数据操作，基于所述目标数据分区执行所述数据操作。具体的，本实施例中，可实现对处于同一目标数据分区的多行数据同时进行修改。例如，如附图2所示，业务1可以携带新创建的数据库事务3对应的事务ID对分区键PK0为0下的多行数据进行修改，这些修改放在内存中，并不会立即生效，对其他数据库事务不可见，并且如果服务端所在的机器发生宕机，这些修改会被丢失。
步骤5，根据所述客户端发送的事务指令处理所述数据事务。
本步骤根据所述客户端发送的事务指令处理所述数据事务之前，需执行接收所述客户端发送的针对所述数据库事务进行处理的所述事务指令步骤。基于此，还可以在接收到针对所述数据库事务进行处理的所述事务指令之后，判断所述事务指令对应的数据库事务是否存在，如果存在，则执行本步骤，根据所述客户端发送的事务指令处理所述数据事务；如果不存在，则向所述客户端返回所述事务指令对应的数据库事务不存在的提醒信息。
本申请实施例所述事务指令，包括事务提交指令和事务取消指令，以下针对这两种事务指令分别进行说明：
1)所述客户端发送的事务指令为所述事务提交指令；
本步骤根据所述客户端发送的事务指令处理所述数据事务，具体采用如下方式实现：
将所述数据库事务提交到事务队列；
从所述事务队列中读取数据库事务，创建所述数据库事务对应的事务日志，并将所述数据库事务的数据操作记录在事务日志中；
将所述事务日志存储至预设数据存储空间中。
在实际应用场景中，服务端可能是同时与若干个客户端进行交互，不同的客户端可能在较短的时间内提交不同的数据库事务，这些数据库事务不能同时执行，因此设置事务队列，将所述数据库事务提交到事务队列，按照顺序依次执行数据库事务。具体的，所述事务队列可以是由数据库事务组成的一种线性表，该事务队列根据数据库事务提交的先后顺序将所述数据库事务进行排列，并且按照排列顺序依次读取所述数据库事务。
例如，如附图2所示，当接收到业务1对应的客户端针对数据库事务3发送的事务提交指令之后，将数据库事务3提交至事务队列当中；此后，对事务队列当中的数据库事务进行处理时，从事务队列当中读取数据库事务3，并将数据库事务3的数据操作记录在对应的事务日志中，并最终将事务日志存储在内存当中。
此外，上述针对所述数据库事务的提交操作完成之后，所述数据库事务被销毁，并回收所述数据库事务对应的事务标识，同时，所述数据库事务所对应的分区键实现解锁，即允许其他数据库事务对所述分区键下的数据进行数据操作，保证了数据库事务的隔离性。隔离性是数据库事务针对并发事务间的冲突提供的安全保证，数据库事务可以通过加锁在并发执行的事务间提供不同级别的分离，从而避免操纵相同的共享对象的多个并发事务的执行可能引起异常情况。
2)所述客户端发送的事务指令为所述事务取消指令；
本步骤根据所述客户端发送的事务指令处理所述数据事务，具体采用如下方式实现：
删除所述数据库事务，并回收所述数据库事务对应的事务标识。由于所述数据库事务并未真正执行，所述数据库事务作废，确保数据库事务的原子性。
除此之外，在具体实施时，所述客户端发送的针对所述数据库事务进行处理的事务指令还包括事务回滚指令，在所述数据库事务提交之前对所述数据库事务进行回滚，放弃之前针对所述数据库事务的修改，并终止处理所述数据库事务。
在具体实施时，本申请提供的所述数据事务处理方法，还可以基于云计算环境中部署的分布式数据库平台实现，所述分布式数据库平台设置有用于访问所述分布式数据库 (如NoSQL数据库)的数据访问接口，业务对应的客户端想要使用NoSQL数据库进行业务数据处理时，通过调用所述数据访问接口，向所述服务端提交基于NoSQL数据库的分区键申请数据库事务，所述服务端通过所述数据访问接口获取业务对应的客户端提交的基于NoSQL数据库的分区键申请数据库事务并进行相应处理；同时，业务对应的客户端还通过所述数据访问接口向所述服务端提交针对所述数据库事务进行处理的事务指令，所述服务端通过所述数据访问接口获取到所述事务指令，根据所述事务指令对所述数据库事务进行处理。
综上所述，本申请提供的所述数据事务处理方法，对所述客户端在所述分区键下进行数据操作的数据库事务进行处理时，为创建的数据库事务分配事务标识，并将所述事务标识返回给所述客户端，由所述客户端通过提交携带所述事务标识的数据操作在所述分区键下执行数据操作，并最终根据所述客户端发送的事务指令对所述数据库事务进行处理，从而使所述数据操作实现事务属性，满足了数据操作的事务性；同时，所述数据事务处理方法实现数据事务的业务逻辑较为简单，确保数据业务具有良好的事务性。
