[0040] Embodiments of the invention
[0041] Embodiments of the present invention
[0042] In order to make the invention purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0043] Figure 1 A schematic diagram of the structure of a distributed data management system is shown. The data processing method provided in the embodiment of the present application can be applied to Figure 1 In the distributed data management system 10 shown.
[0044] like Figure 1 As shown, the distributed data management system 10 includes a primary computer room 101 and one or more secondary computer rooms 102 (only three are shown in the figure). The primary computer room 101 is used to receive data information synchronized by the secondary computer room 102, and synchronize the information to other secondary computer rooms, so as to maintain data consistency. The secondary computer room 102 can receive the written data of the local user, and synchronize the written data to the primary computer room 101. The secondary computer room 102 can also receive data synchronized from the primary computer room 101.
[0045] Based on the above-mentioned distributed data management system 10, in order to solve the problem that when multiple secondary computer rooms simultaneously write the same data in such a distributed data management system, there is a simultaneous writing conflict, which affects the stability of the computer room, the present application provides a data processing method, such as Figure 2The figure is a flow chart of a data processing method provided in an embodiment of the present application. The data processing method is applied to a primary computer room. The method comprises the following steps:
[0046] Step 201: upon receiving first data sent by a secondary computer room, extracting first content and a first timestamp contained in the first data.
[0047] In an embodiment of the present application, when a local user of a secondary computer room writes data in the secondary computer room, the secondary computer room synchronizes the data written by the local user to the primary computer room so that the primary computer room synchronizes the data to other secondary computer rooms, thereby ensuring the consistency of data in multiple active computer rooms. When the primary computer room receives the first data sent by the secondary computer room, the primary computer room first extracts information from the first data before synchronously writing the first data into the memory of the primary computer room, and extracts the first content and the first timestamp contained in the primary data. The so-called timestamp refers to a complete and verifiable data that can indicate that a piece of data existed before a certain time. The timestamp is a piece of data, and the size of the timestamp can reflect the time when a piece of data was generated. Specifically, the larger the timestamp, the later the data was generated. The first data contains the first timestamp information, indicating that when the data in the secondary computer room is written, the secondary computer room will assign a timestamp to the written data.
[0048] Step 202: If there is second data with the same content as the first content in the storage of the first-level computer room, extract the timestamp of the second data.
[0049] In the embodiment of the present application, after extracting the first content of the received first data, the memory of the first computer room is searched to see whether there is data with the same content as the first content. If the second data with the same content as the first content is retrieved, the second timestamp of the second data is extracted. It can be understood that since the second computer room will give a timestamp to the written data when writing data, and the data in the first computer room is synchronized from the second computer room, the first computer room itself does not have the data writing function, so the data stored in the memory of the first computer room are all data with timestamps. That is, the second timestamp contained in the second data can be extracted from the second data.
[0050] Step 203: If the first timestamp is greater than the second timestamp, the second data in the memory of the first-level computer room is deleted and the first data is stored in the memory of the first-level computer room.
[0051] In the embodiment of the present application, the extracted first timestamp is compared with the second timestamp. When the first timestamp is greater than the second timestamp, it means that the generation time of the first data is after the generation time of the second data. The data generated first is deleted from the memory of the first-level computer room, and the data generated later is stored in the memory of the first-level computer room, that is, the first data is stored in the memory. If the first timestamp is less than the second timestamp, it means that the generation time of the first data is before the generation time of the second data, so the second data stored in the first-level computer room still needs to be saved, so the first-level computer room refuses to write the first data.
[0052] According to the above description, the data processing method provided by the embodiment of the present application includes: when receiving the first data sent by the secondary computer room, extracting the first content and the first timestamp contained in the first data; if there is second data with the same content as the first content in the memory of the primary computer room, extracting the timestamp of the second data; if the first timestamp is greater than the second timestamp, deleting the second data in the memory of the primary computer room and storing the first data in the memory of the primary computer room. This method is based on a hierarchical distributed data storage system. When the secondary computer room synchronizes data to the primary computer room, the primary computer room judges the data to be synchronized based on the content of the data and the timestamp of the data. For data with the same content, only the data with a larger timestamp is accepted for synchronization, thereby avoiding data writing conflicts and improving the stability of multi-active computer rooms.
[0053] Further, if the first timestamp is greater than the second timestamp, after deleting the second data in the memory of the primary computer room and storing the first data in the memory of the primary computer room, the method further includes:
[0054] The first data is sent to all secondary computer rooms.
[0055] In an embodiment of the present application, after determining that the first data meets the write condition and storing the first data in the memory of the primary computer room, the primary computer room will resynchronize and send the first data to all secondary computer rooms, so as to achieve the consistency of the latest data in all computer rooms. It can be understood that the above-mentioned first data is also synchronized to the primary computer room by one of the secondary computer rooms. Here, the secondary computer room that sends the above-mentioned first data to the primary computer room can be called the initial computer room. After the primary computer room stores the first data in the memory of the primary computer room, it is also possible to no longer synchronously send the first data to the initial computer room. It only needs to be sent to other secondary computer rooms.
[0056] Furthermore, the data processing method further includes:
[0057] If the second data having the same content as the first data does not exist in the memory of the first computer room, storing the first data in the memory of the first computer room;
[0058] Send primary data to all secondary computer rooms.
[0059] In the embodiment of the present application, if it is determined that there is no second data with the same content as the first data in the memory of the first-level computer room, the first data is stored in the memory of the first-level computer room to achieve data synchronization. After the first data is stored in the memory of the first-level computer room, the first-level computer room sends the first data to all the second-level computer rooms to achieve data consistency in all computer rooms.
[0060] like Figure 3 FIG. 1 is another flow chart of a data processing method provided in an embodiment of the present application. The data processing method is applied to a secondary computer room. The method includes the following steps:
[0061] Step 301, when a first data write request is detected, the source of the first data to be written is obtained;
[0062] In the embodiment of the present application, when the secondary computer room detects data writing, the source of the first data to be written is obtained. The first data to be written to the secondary computer room can be sent to the secondary computer room during data synchronization in the primary computer room, or can be written by a local user in the secondary computer room.
[0063] Step 302: If the first data originates from a primary computer room, extract the first content and the first timestamp contained in the first data.
[0064] In an embodiment of the present application, when it is determined that the first data originates from the first-level computer room, that is, the first data is sent to the second-level computer room when the first-level computer room performs data synchronization, the first content and the first timestamp contained in the first data are extracted.
[0065] Step 303: If there is second data with the same content as the first content in the storage of the secondary computer room, extract the second timestamp contained in the second data.
[0066] In the embodiment of the present application, after extracting the first content of the first data, a search is performed in the memory of the secondary computer room to determine whether there is second data with the same content as the first content based on the first content. When the second data with the same content as the first content is found in the memory of the secondary computer room, a second timestamp included in the second data is extracted.
[0067] Step 304: If the first timestamp is greater than the second timestamp, the second data in the secondary computer room memory is deleted and the first data is stored in the secondary computer room memory.
[0068] In an embodiment of the present application, the first timestamp of the extracted first data is compared with the second timestamp of the second data. When the first timestamp is greater than the second timestamp, it indicates that the generation time of the first data is later than the generation time of the second data. The second data stored in the memory of the secondary computer room is deleted and the first data is stored in the memory of the secondary computer room, that is, the data stored in the memory of the secondary computer room is updated to the first data, that is, the first data in the first computer room is synchronized to the secondary computer room. It can be understood that if the first time error is not greater than the second timestamp, it means that the generation time of the first data is earlier than the generation time of the second data. In this case, the secondary computer room does not accept the writing of the first data and still retains the second data. Furthermore, since the second data stored in the secondary computer room will also be synchronized to the primary computer room, the primary computer room will update the first data stored in the memory of the primary computer room to the second data and synchronize the second data to other secondary computer rooms, thereby achieving consistency of data in multiple active computer rooms.
[0069] Furthermore, the above method also includes:
[0070] If the second data having the same content as the first data does not exist in the secondary computer room memory, the first data is stored in the secondary computer room memory.
[0071] In an embodiment of the present application, when it is detected that there is no second data in the secondary computer room memory having the same content as the first data sent from the primary computer room, it means that the first data is new data, so the first data is stored in the memory of the secondary computer room.
[0072] Furthermore, the above method also includes:
[0073] If the first data is locally input from the secondary computer room, obtain the third content included in the first data and generate a third timestamp for the first data;
[0074] If there is fourth data with the same content as the third content in the memory of the secondary computer room, obtaining a fourth timestamp included in the fourth data;
[0075] If the third timestamp is greater than the fourth timestamp, the fourth data in the memory of the secondary computer room is deleted and the first data is stored in the memory of the secondary computer room, and the first data is sent to the primary computer room;
[0076] If the third timestamp is not greater than the fourth timestamp, generate fifth data, the fifth data includes the third content and the fifth timestamp, the value of the fifth timestamp is equal to the fourth timestamp plus one, store the fifth data in the memory of the secondary computer room and send the fifth data to the primary computer room.
[0077] In an embodiment of the present application, if it is identified that the first data is sourced from a local input in a secondary computer room, the content of the data is obtained, and the content of the first data is determined to be the third content. The secondary computer room automatically generates a corresponding third timestamp for the data based on the time of data input. It is searched whether there is fourth data with the same content as the third content in the memory of the secondary computer room. If so, a fourth timestamp of the fourth data is obtained. The third timestamp is compared with the fourth timestamp. If the third timestamp is greater than the fourth timestamp, the fourth data in the memory of the secondary computer room is deleted and the first data is stored in the memory of the secondary computer room. The first data is sent to the primary computer room so that the primary computer room can synchronize the data to other secondary computer rooms. If the third timestamp is not greater than the fourth timestamp, the fifth data is generated. The fifth data includes the third content and the fifth timestamp. The value of the fifth timestamp is equal to the fourth timestamp plus 1. For example, the third timestamp of the first data input is 123456, and the fourth timestamp of the fourth data stored in the memory of the secondary computer room is 123459, which means that the fourth data is not input locally but synchronized from the primary computer room. Since there are certain differences in the local stamps of different secondary computer rooms, the timestamp of the data stored in the secondary computer room may be greater than the timestamp of the same data input locally. At this time, a fifth timestamp is determined to be 123459+1=123460, and it is determined that the fifth data contains the third content and the fifth timestamp. The fifth data is stored in the memory of the secondary computer room, and the fifth data is sent to the primary computer room so that the primary computer room can synchronize the data to other secondary computer rooms.
[0078] The data processing method provided by the method ensures that the locally input data can be input, and can keep the timestamp of the data incremented, thus avoiding data writing conflicts and effectively ensuring the consistency of data stored in multi-active computer rooms.
[0079] Furthermore, the above method also includes:
[0080] If the fourth data having the same content as the third content does not exist in the memory of the secondary computer room, the first data is stored in the memory of the secondary computer room;
[0081] The first data is sent to the primary computer room.
[0082] In an embodiment of the present application, when data with the same content cannot be retrieved from the memory of the secondary computer room when the data input locally is input, the data input locally is stored in the memory of the computer room and synchronized to the primary computer room so that the primary computer room can synchronize the data to other secondary computer rooms.
