Description

Technical Field

[0001] The present invention relates to the field of big data technology, and in particular, to a data dual-writing method and device. Background Art

[0002] In a distributed system, since data is scattered in multiple unit databases according to a certain dimension, inevitably, at the transaction service entry, gateway routing information is required to tell which unit database the transaction data is in. For example, a banking system is usually divided into units centered on the customer number, that is, the customer number and other entities under the same customer number, such as account numbers and card numbers, should be assigned to the same unit. Then, the corresponding relationship between the customer number and the account number, or the customer number and the card number, needs to be maintained in the gateway routing information, so that it can be determined at the entry which unit the account transaction or card transaction should go to.

[0003] This also leads to such a problem: when new account numbers or card numbers are generated, or when account numbers or card numbers are logically deleted, the corresponding relationship between the customer number and the account number, or the customer number and the card number, needs to be synchronized and maintained in the gateway routing. Usually, the gateway routing information is in the full-scale database (cache), while the entity customer numbers, card numbers, and account numbers are in the unit database. In this way, different databases need to be operated simultaneously and both operations need to succeed, which will cause a large number of distributed transactions, thereby reducing concurrency and resulting in low efficiency. Summary of the Invention

[0004] An embodiment of the present invention provides a data dual-writing method to achieve data dual-writing and improve the efficiency and success rate of data dual-writing. The method includes:

[0005] After receiving a write request, write the data into the unit database and mark the status of the written data as to be synchronized;

[0006] After receiving the write success notification feedback from the unit database, write the relationship data of the data into the gateway routing information cache;

[0007] After receiving the write success notification feedback from the gateway routing information cache, write the relationship data of the data into the gateway routing information table in the gateway routing information database without waiting for the feedback from the gateway routing information database;

[0008] Query asynchronously through a process whether the relationship data corresponding to the data with the status of to be synchronized in the unit database is successfully written into the gateway routing information table;

[0009] If the write is successful, update the status of the data in the unit database to updated; <>

[0010] If the write is not successful, supplement and write the relationship data of the data into the gateway routing information table. When the supplementary write is successful, update the status of the data in the unit database to updated.

[0011] An embodiment of the present invention provides a data dual-writing device for implementing data dual-writing and improving the efficiency and success rate of data dual-writing. The device includes:

[0019] In an embodiment of the present invention, after receiving a write request, data is written into the unit database, and the status of the written data is marked as to be synchronized; after receiving a write success notification feedback from the unit database, the relationship data of the data is written into the gateway routing information cache; after receiving a write success notification feedback from the gateway routing information cache, the relationship data of the data is written into the gateway routing information table in the gateway routing information database without waiting for a feedback from the gateway routing information database; an asynchronous process is used to query whether the relationship data corresponding to the data with the status of to be synchronized in the unit database is successfully written into the gateway routing information table; if the write is successful, the status of the data in the unit database is updated to updated; if the write is not successful, the relationship data of the data is supplemented and written into the gateway routing information table, and when the supplementary write is successful, the status of the data in the unit database is updated to updated.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer and more understandable, the following further elaborates on the embodiments of the present invention with reference to the accompanying drawings. Herein, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but do not limit the present invention.

[0031] In the description of this specification, the terms "include", "comprise", "have", "contain", etc. are all open-ended terms, meaning including but not limited to. The descriptions referring to terms such as "one embodiment", "one specific embodiment", "some embodiments", "for example", etc. mean that the specific features, structures or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. The step sequences involved in each embodiment are used to schematically illustrate the implementation of the present application, and the step sequences are not limited and can be adjusted appropriately as needed.

[0032] Figure 1 This is the process of the data dual writing method in the embodiments of the present invention Figure 1 , as Figure 1 shown, the method includes:

[0033] Step 101, after receiving a write request, write the data into the unit database and mark the status of the written data as to be synchronized;

[0034] Step 102, after receiving the write success notification feedback from the unit database, write the relationship data of the data into the gateway routing information cache;

[0035] Step 103: After receiving the write success notification from the gateway routing information cache feedback, write the relationship data of the data into the gateway routing information table in the gateway routing information database without waiting for the feedback from the gateway routing information database;

[0036] Step 104: Use the asynchronous process query unit to check whether the relationship data corresponding to the data with the status of to be synchronized in the unit database is successfully written into the gateway routing information table;

[0037] Step 105: If the write is successful, update the status of the data in the unit database to updated;

[0038] Step 106: If the write is not successful, supplementarily write the relationship data of the data into the gateway routing information table. When the supplementary write is successful, update the status of the data in the unit database to updated.

[0039] In the embodiment of the present invention, while writing the unit database information, the gateway routing information cache is also written, and then the gateway routing information database is written. However, it does not wait for the feedback from the gateway routing information database. Instead, an asynchronous process is used to query whether the gateway routing information table is successfully written. If the write is successful, no processing is performed. If the write is not successful, the relationship data of the data is supplementarily written into the gateway routing information table. When the supplementary write is successful, the status of the data in the unit database is updated to updated. This avoids a large number of distributed transactions and improves the efficiency of data dual writing. At the same time, for the small probability event that the write to the gateway routing information table is not successful, compensation is made through the asynchronous process to ensure success, improving the success rate of data dual writing.

[0040] Figure 2 This is the flow of the data dual writing method in the embodiment of the present invention Figure 2 It includes the content of Step 101 and Step 103, and error handling is added on this basis. It involves the processing process after receiving the write request. Among them, when writing the relationship data, the relationship data is first inserted into the gateway routing information cache and then into the gateway routing information table.

[0041] In one embodiment, the method further includes:

[0042] After receiving the deletion request, mark the relationship data corresponding to the data in the deletion request in the gateway routing information table as not in use, and do not perform deletion in the gateway routing information database.

[0043] Under normal circumstances, it should be restricted that the relationship data involving the gateway routing information table such as customers, accounts, cards, etc. only has logical marked deletion and no physical deletion, that is, mark the relationship data corresponding to the data in the deletion request in the gateway routing information table as not in use, and do not perform deletion in the gateway routing information database.

[0044] In one embodiment, the method further includes:

[0045] When a read request is received, read the corresponding relationship data of the data in the read request in the gateway routing information cache. If the corresponding relationship data is not in the gateway routing information cache, read the gateway routing information table and put the corresponding relationship data of the gateway routing information table into the gateway routing information cache;

[0046] When an update request is received, perform an update operation based on the type of the relationship data corresponding to the data in the update request.

[0047] Figure 3 This is the processing flow of the read request during data dual writing in the embodiment of the present invention. Among them, the principle of the read request is to read from the network routing information cache first.

[0048] In one embodiment, performing an update operation based on the type of the relationship data corresponding to the data in the update request includes:

[0049] If the relationship data stored in the gateway routing information cache meets the first condition, update the gateway routing information cache based on the relationship data corresponding to the data in the update request, and then update the gateway routing information table; the first condition is that the relationship data is in the key-value and data-value structure, and the number of read requests received within a preset duration is greater than the first threshold, and the number of update requests received within a preset duration is less than the second threshold:

[0050] If the relationship data stored in the gateway routing information cache meets the second condition, delete the historical data of the relationship data corresponding to the data in the update request in the gateway routing information cache, and update the gateway routing information table based on the relationship data corresponding to the data in the update request; the second condition is that the number of update requests received within a preset duration is greater than the third threshold.

[0051] Figure 4 This is the first processing flow of the update request during data dual writing in the embodiment of the present invention, corresponding to the first condition, Figure 5 This is the second processing flow of the update request during data dual writing in the embodiment of the present invention, corresponding to the second condition. That is, under the first condition, first update the gateway routing information cache, and then update the gateway routing information table in the gateway routing information database. Under the second condition, the lazy loading idea is adopted, that is, only delete the relationship data in the gateway routing information cache first, and then update the gateway routing information table in the gateway routing information database, avoiding the meaningless cost of frequently updating the cache. In the above second condition, the update requests received within a preset duration can be simple data or worthless data. Worthless data is data that is not commonly used but requires complex calculations.

[0052] In one embodiment, the method further includes:

[0053] If the relational data stored in the gateway routing information cache meets the second condition, the received read request and update request are executed serially.

[0054] In the above embodiment, serial execution can ensure the consistency of the relational data in the gateway routing information cache and the gateway routing information database in the case of high concurrency.

[0055] Figure 6 The following is a flowchart of the asynchronous process in the embodiment of the present invention. In one embodiment, it is queried whether the relational data corresponding to the data with the status of to-be-synchronized in the unit database is successfully written in the gateway routing information table through the asynchronous process, including:

[0056] Poll and extract the key values of the data with the status of to-be-synchronized in the unit database;

[0057] Query whether the corresponding relational data is successfully written in the gateway routing information table through the key value.

[0058] To sum up, in the method proposed in the embodiment of the present invention, while writing the unit database information, the gateway routing information cache is also written, and then the gateway routing information database is written. However, instead of waiting for the feedback from the gateway routing information database, an asynchronous process is used to query whether the gateway routing information table is successfully written. If it is successfully written, no processing is performed. If it is not successfully written, the relational data of the data is supplemented and written into the gateway routing information table. When the supplementary writing is successful, the status of the data in the unit database is updated to updated. In this way, a large number of distributed transactions are avoided, and the efficiency of data dual writing is improved; at the same time, for the small probability event that the writing of the gateway routing information table is not successful, compensation is made through the asynchronous process to ensure success, and the success rate of data dual writing is improved. In addition, under the second condition, the lazy loading idea is adopted, that is, only the relational data in the gateway routing information cache is deleted first, and then the gateway routing information table in the gateway routing information database is updated, avoiding the meaningless cost of frequently updating the cache, and the serial execution of the read request and the write request can ensure the consistency of the relational data in the gateway routing information cache and the gateway routing information database in the case of high concurrency.

[0065] In one embodiment, the data write success query module is specifically configured to:

[0066] Poll and extract the key values of the data with a status of to-be-synchronized in the unit database;

[0071] When receiving a read request, read the relational data corresponding to the data in the read request in the gateway routing information cache; if the corresponding relational data is not in the gateway routing information cache, read the gateway routing information table, and put the relational data corresponding to the gateway routing information table into the gateway routing information cache;

[0072] When receiving an update request, perform an update operation based on the type of the relational data corresponding to the data in the update request

[0073] In one embodiment, the request processing module is further configured to:

[0074] If the relationship data stored in the gateway routing information cache meets the first condition, update the gateway routing information cache based on the relationship data corresponding to the data in the update request, and then update the gateway routing information table; the first condition is that the relationship data is in the key-value and data-value structure, and the number of read requests received within a preset time period is greater than the first threshold, and the number of update requests received within a preset time period is less than the second threshold:

[0075] If the relationship data stored in the gateway routing information cache meets the second condition, delete the historical data of the relationship data corresponding to the data in the update request in the gateway routing information cache, and update the gateway routing information table based on the relationship data corresponding to the data in the update request; the second condition is that the number of update requests received within a preset time period is greater than the third threshold.

[0076] In summary, in the device proposed in the embodiment of the present invention, while writing the unit database information, the gateway routing information cache is also written, and then the gateway routing information database is written. However, instead of waiting for the feedback from the gateway routing information database, an asynchronous process is used to query whether the writing of the gateway routing information table is successful. If it is successful, no processing is done. If it is not successful, the relationship data of the data is supplemented and written into the gateway routing information table. When the supplementary writing is successful, the status of the data in the unit database is updated to updated. This avoids a large number of distributed transactions and improves the efficiency of data dual writing. At the same time, for the small probability event of unsuccessful writing of the gateway routing information table, compensation is made through the asynchronous process to ensure success, improving the success rate of data dual writing. In addition, under the second condition, the lazy loading idea is adopted, that is, only the relationship data in the gateway routing information cache is deleted first, and then the gateway routing information table in the gateway routing information database is updated, avoiding the meaningless cost of frequent cache updates, and the serial execution of read requests and write requests can ensure the consistency of the relationship data in the gateway routing information cache and the gateway routing information database under high concurrency.
