技术领域Technical field

本发明涉及金融科技(Fintech)的分布式存储领域，尤其涉及一种基于Redis协议的KV数据存储方法及装置。The invention relates to the field of distributed storage of financial technology (Fintech), in particular to a KV data storage method and device based on the Redis protocol.

背景技术Background technique

随着计算机的普及和信息技术的进步，特别是企业计算机网络的飞速发展，企业信息安全的重要性日趋明显，因而对作为企业信息安全的一项重要内容的数据备份提出了严格的要求。目前为各企业广泛使用的一种分布式存储数据库——Redis数据库，通过采用主从复制模式，即当一个或多个从节点连接上主节点时，主节点会将数据复制到一个或多个从节点上，从而实现对数据的多个备份。这些备份数据可以很大程度提高Redis服务的读性能，同时也是保证Redis服务高可用和分布式的基础。With the popularization of computers and the advancement of information technology, especially the rapid development of corporate computer networks, the importance of corporate information security has become increasingly obvious. Therefore, strict requirements have been placed on data backup as an important part of corporate information security. Currently, Redis database, a distributed storage database widely used by various enterprises, adopts a master-slave replication mode, that is, when one or more slave nodes are connected to the master node, the master node will copy the data to one or more From the node, multiple backups of data can be realized. These backup data can greatly improve the read performance of the Redis service, and it is also the basis for ensuring the high availability and distribution of the Redis service.

然而，在Redis数据库中，基于Redis协议的数据在进行数据备份时，主节点到多个从节点的数据复制过程是异步进行的。这种异步复制的方式可能会出现主从节点数据不一致的情况，从而不能保证较强的数据一致性。例如，在长时间断网或者主节点宕机时，Redis数据库就会选举某个从节点作为新的主节点，但原主节点还未及时将最新数据发送至该新的主节点进行备份，从而导致该新的主节点中的数据不完整。However, in the Redis database, when data is backed up based on the Redis protocol, the data replication process from the master node to multiple slave nodes is performed asynchronously. This asynchronous replication method may cause data inconsistency between the master and slave nodes, which cannot guarantee strong data consistency. For example, when the network is disconnected for a long time or the master node is down, the Redis database will elect a slave node as the new master node, but the original master node has not sent the latest data to the new master node for backup in time, resulting in The data in the new master node is incomplete.

下面结合说明书附图对本发明实施例作进一步详细描述。The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.

如图1所示，为本发明实施例一种可能的***架构，基于该***架构可实现对基于Redis协议的KV数据存储。该架构包括数据存储装置102和数据库103。可选地，该架构还可以包括客户端101。As shown in FIG. 1, it is a possible system architecture of an embodiment of the present invention. Based on this system architecture, KV data storage based on the Redis protocol can be realized. The architecture includes a data storage device 102 and a database 103. Optionally, the architecture may also include the client 101.

其中，数据存储装置102用于将Redis协议数据转换为KV协议数据，并将KV协议数据发送至数据库103进行存储；以及，用于基于客户端101的请求，从数据库103获取KV协议数据并将该KV协议数据转换为Redis协议数据，然后将Redis协议数据发送至客户端101。Among them, the data storage device 102 is used to convert Redis protocol data into KV protocol data, and send the KV protocol data to the database 103 for storage; and, based on the request of the client 101, obtain the KV protocol data from the database 103 and The KV protocol data is converted into Redis protocol data, and then the Redis protocol data is sent to the client 101.

数据库103，用于存储基于KV协议的数据。The database 103 is used to store data based on the KV protocol.

客户端101，用于向数据存储装置102发送请求消息，以请求获取Redis协议数据，并接收来自于数据存储装置102的Redis协议数据。The client 101 is configured to send a request message to the data storage device 102 to request to obtain Redis protocol data, and to receive the Redis protocol data from the data storage device 102.

基于图1中的***架构，本发明实施例提供了一种基于Redis协议的KV数据存储方法，该方法可由图1中的数据存储装置102执行，如图2所示，该方法包括以下步骤：Based on the system architecture in FIG. 1, an embodiment of the present invention provides a KV data storage method based on the Redis protocol. The method can be executed by the data storage device 102 in FIG. 1. As shown in FIG. 2, the method includes the following steps:

步骤201，获取Redis协议数据，获取所述Redis协议数据的第一关键字和所述第一关键字对应的数据，其中，所述第一关键字对应的数据的数据类型为预设类型。Step 201: Obtain Redis protocol data, and obtain a first keyword of the Redis protocol data and data corresponding to the first keyword, wherein the data type of the data corresponding to the first keyword is a preset type.

Redis协议数据的数据类型包括但不限于以下四种：字符串(String)、哈希(Hash)、集合(Set)、列表(List)。其中，Redis协议数据均可以通过Key-Value值来表示。The data types of Redis protocol data include but are not limited to the following four types: string (String), hash (Hash), set (Set), and list (List). Among them, Redis protocol data can be represented by Key-Value values.

步骤202，根据所述第一关键字对应的数据的数据类型，获取所述数据类型对应的预设标识符号。Step 202: Obtain a preset identification symbol corresponding to the data type according to the data type of the data corresponding to the first keyword.

步骤203，基于所述第一关键字和所述预设标识符号，得到第二关键字；根据所述第二关键字和所述第一关键字对应的数据，得到KV协议数据，所述预设标识符号用于指示所述KV协议数据的数据类型与所述第一关键字对应的数据的数据类型一致。Step 203: Obtain a second keyword based on the first keyword and the preset identification symbol; obtain KV protocol data according to the data corresponding to the second keyword and the first keyword. The identification symbol is used to indicate that the data type of the KV protocol data is consistent with the data type of the data corresponding to the first keyword.

KV协议数据的数据类型包括但不限于以下四种：字符串(String)、哈希(Hash)、集合(Set)、列表(List)。其中，KV协议数据均可以通过Key-Value值来表示。The data types of KV protocol data include but are not limited to the following four types: String, Hash, Set, List. Among them, KV protocol data can all be represented by Key-Value values.

将Redis协议数据转换为KV协议数据时，若Redis协议数据的数据类型为字符串，则转换后的KV协议数据的数据类型也为字符串；若Redis协议数据的数据类型为哈希，则转换后的KV协议数据的数据类型也为哈希；若Redis协议数据的数据类型为集合，则转换后的KV协议数据的数据类型也为集合；若Redis协议数据的数据类型为列表，则转换后的KV协议数据的数据类型也为列表。When converting Redis protocol data to KV protocol data, if the data type of the Redis protocol data is a string, the data type of the converted KV protocol data is also a string; if the data type of the Redis protocol data is a hash, then the conversion The data type of the subsequent KV protocol data is also a hash; if the data type of the Redis protocol data is a collection, the data type of the converted KV protocol data is also a collection; if the data type of the Redis protocol data is a list, the converted The data type of the KV protocol data is also a list.

对于Redis协议数据，String属于简单数据类型，因而在将数据类型为String的Redis协议数据转换为KV协议数据时，转换得到的KV协议数据包括一个数据项，即实际数据。Hash、Set和List属于复杂数据类型，因而在将数据类型为Hash、Set或List的Redis协议数据转换为KV协议数据时，转换得到的KV协议数据包括至少两个数据项，分别为元数据和实际数据，其中元数据主要记录Hash、Set或List这三类数据的额外信息，比如当数据类型为Hash、Set时，元数据信息包括数据容量(Size)、过期时间(Time to Live，TTL)、标志位(Flag)等；当数据类型为List时，元数据信息包括头部信息(Head)、尾部信息(Tail)、数据容量(Size)、过期时间(Time to Live，TTL)、标志位(Flag)等。For Redis protocol data, String is a simple data type. Therefore, when the Redis protocol data whose data type is String is converted into KV protocol data, the converted KV protocol data includes a data item, that is, actual data. Hash, Set, and List are complex data types. Therefore, when the Redis protocol data with the data type of Hash, Set, or List is converted into KV protocol data, the converted KV protocol data includes at least two data items, namely metadata and Actual data. Metadata mainly records additional information about the three types of data: Hash, Set, or List. For example, when the data type is Hash, Set, the metadata information includes data size (Size) and expiration time (Time to Live, TTL) , Flag (Flag), etc.; when the data type is List, the metadata information includes header information (Head), tail information (Tail), data capacity (Size), expiration time (Time to Live, TTL), flag bit (Flag) and so on.

步骤204，将所述KV协议数据发送至KV数据库进行存储。Step 204: Send the KV protocol data to the KV database for storage.

基于该方案，由于KV数据库可以保证应用KV协议数据的主从节点之间的数据一致性，本方案将获取到的Redis协议数据转换为KV协议数据，并发送至KV数据库进行存储，因而有助于保证应用Redis协议数据的主从节点之间的数据强一致性。从而，当Redis服务在长时间断网或者主节点宕机而造成主从节点数据不一致时，通过该方案有助于保证应用Redis协议数据的主从节点之间的数据一致性。Based on this solution, since the KV database can ensure data consistency between the master and slave nodes that apply KV protocol data, this solution converts the obtained Redis protocol data into KV protocol data and sends it to the KV database for storage, which is helpful To ensure strong data consistency between the master and slave nodes that apply Redis protocol data. Therefore, when the Redis service is disconnected from the network for a long time or the master node is down and the data of the master and slave nodes are inconsistent, this solution helps to ensure the data consistency between the master and slave nodes that apply the Redis protocol data.

下面根据Redis协议数据的数据类型，给出将Redis协议数据转换为KV协议数据的具体实现方式。According to the data type of Redis protocol data, the specific implementation method of converting Redis protocol data into KV protocol data is given below.

情形一、Redis协议数据的数据类型为String，Redis协议数据包含第一关键字和第一取值。Case 1: The data type of the Redis protocol data is String, and the Redis protocol data includes the first keyword and the first value.

下面结合一个示例进行说明。如表1所示，是Redis协议数据的数据类型为String时的信息的示例。一条String类型的Redis协议数据，包含的关键字(Key)为alice_account，取值(Value)为43000212333111110000。Let's describe with an example. As shown in Table 1, it is an example of information when the data type of the Redis protocol data is String. A string of Redis protocol data contains the key (Key) as alice_account and the value (Value) as 4300212333111110000.

其中，这里的关键字(alice_account)也称为第一关键字，这里的取值(43000212333111110000)也称为第一取值。The keyword (alice_account) here is also called the first keyword, and the value here (43000212333111110000) is also called the first value.

表1Table 1

如表2所示，是对表1所示的Redis协议数据进行转换得到的KV协议数据。As shown in Table 2, it is the KV protocol data obtained by converting the Redis protocol data shown in Table 1.

表2Table 2

参考表2，其中，第二关键字为1alice_account，该关键字1alice_account也可以称为实际数据关键字。第二关键字1alice_account是根据第一关键字alice_account和第一标识字符“1”得到的，即在第一关键字alice_account之前添加第一标识字符“1”，得到第二关键字1alice_account，第一标识字符“1”用于指示该KV协议数据的数据类型与第一关键字alice_account对应的数据的数据类型一致，均为String。Refer to Table 2, where the second key is 1alice_account, and this key 1alice_account may also be called the actual data key. The second keyword 1alice_account is obtained based on the first keyword alice_account and the first identification character "1", that is, the first identification character "1" is added before the first keyword alice_account to obtain the second keyword 1alice_account, the first identification The character "1" is used to indicate that the data type of the KV protocol data is consistent with the data type of the data corresponding to the first keyword alice_account, and both are String.

该第二关键字对应的取值为43000212333111110000，即第二关键字对应的取值与第一关键字对应的取值相同，均为第一取值。The value corresponding to the second keyword is 4300212333111110000, that is, the value corresponding to the second keyword is the same as the value corresponding to the first keyword, and both are the first value.

情形二、Redis协议数据的数据类型为Hash，Redis协议数据包含第一关键字和第二取值。Case 2: The data type of the Redis protocol data is Hash, and the Redis protocol data includes the first keyword and the second value.

下面结合一个示例进行说明。如表3所示，是Redis协议数据的数据类型为Hash时的信息的示例。一条Hash类型的Redis协议数据，包含的关键字(Key)为alice，取值(Key)分别为name(爱丽丝)、age(18)、country(中国)和birthday(2000/1/1)。Let's describe with an example. As shown in Table 3, it is an example of information when the data type of the Redis protocol data is Hash. A piece of Hash type Redis protocol data contains the key (Key) as alice, and the value (Key) is name (Alice), age (18), country (China) and birthday (2000/1/1).
