Description

Technical Field

[0001] The present invention relates to the field of big data technology, and in particular to a data processing method, device, electronic device and storage medium. Background Art

[0002] With the rapid development of information technology, the Internet has entered the era of big data. The data that Internet applications need to process is becoming larger and more complex, and how to quickly respond to big data processing has become the focus. And how to quickly and low-load randomly and fairly extract multiple records from massive data for operation has become the top priority.

[0003] At present, in order to reduce the crash caused by excessive data volume in database query, the traditional coupon distribution model will first perform paging query during the coupon drawing process; then calculate the number of drawings required for each page, and the calculation formula is: the number of data required to be drawn for each page = the number of lucky users still to be drawn * the number of pages / the total number of applications to be issued. If there is a remainder, add 1 (adding 1 is to avoid insufficient total number of drawings after all drawings are completed); extract the data from the paging query according to the calculated number of drawings.

[0004] However, this model is not completely fair, because the application records are stored in ascending chronological order, and in order to prevent the number of distributions remaining at the end, the priority application records will actually be drawn in excess of the equal proportion (the remainder plus 1), which is unfair to users who apply later, and each piece of data has only one chance to be drawn after a paginated query, and the randomness is poor. Summary of the invention

[0005] In view of this, the present invention provides a data processing method, device, electronic device and storage medium to solve at least one of the above-mentioned problems.

[0006] According to a first aspect of the present invention, there is provided a data processing method, the method comprising:

[0007] Acquire multiple user data, the user data includes: a user number, the user number is associated with the user contact information;

[0008] Perform a predetermined number of traversal operations on multiple user numbers based on a random number generation algorithm to obtain a predetermined number of lucky numbers;

[0009] In response to the predetermined number of lucky numbers being different, notification information is sent based on user contact information corresponding to each lucky number.

[0010] According to a second aspect of the present invention, there is provided a data processing device, the device comprising:

[0011] A data acquisition unit, used to acquire a plurality of user data, the user data including: a user number, the user number is associated with the user contact information;

[0015] According to a fourth aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the computer program implements the steps of the above method when executed by a processor.

[0016] It can be seen from the above technical solution that by performing a predetermined number of traversal operations on the obtained multiple user numbers, a predetermined number of different lucky numbers are obtained, and then notification information is sent based on the user contact information corresponding to each lucky number. Compared with the existing lucky user extraction scheme based on paging, this technical solution extracts the same number of times for each user data, which ensures the fairness of the extraction and has better randomness.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Since the current coupon extraction mode is based on paging extraction, it is not completely fair to the applicants, and each piece of user data has only one extraction opportunity after paging query, and the randomness is poor. Based on this, the embodiment of the present invention provides a data processing solution, which extracts the same number of times for each piece of user data, ensuring the fairness of the extraction and good randomness. The embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0025] Figure 1 is a flow chart of a data processing method according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0026] Step 101, obtaining a plurality of user data, the user data including: a user number, the user number is associated with the user contact information.

[0027] Step 102: Perform a predetermined number of traversal operations on multiple user numbers based on a random number generation (eg, RNG) algorithm to obtain a predetermined number of lucky numbers.

[0028] Step 103: In response to the predetermined number of lucky numbers being different, sending notification information based on user contact information corresponding to each lucky number.

[0029] In one embodiment, when there are identical numbers among the predetermined number of lucky numbers, the traversal operation on the multiple user numbers may be continued based on the random number generation algorithm according to the number of identical numbers to obtain the predetermined number of different lucky numbers.

[0030] Specifically, the traversal operation may be continued on the multiple user numbers based on the random number generation algorithm, one less than the number of identical numbers, to obtain the lucky number again.

[0031] A predetermined number of different lucky numbers are obtained by performing a predetermined number of traversal operations on the obtained multiple user numbers, and then notification information is sent based on the user contact information corresponding to each lucky number. Compared with the existing lucky user extraction scheme based on paging, the embodiment of the present invention extracts each user data the same number of times, which ensures the fairness of the extraction and has better randomness.

[0032] In a specific implementation process, the traversal operation of step 102 includes: presetting a secure random program based on a random number generation algorithm; and then calling the secure random program to perform a predetermined number of traversal operations on the multiple user numbers.

[0033] In actual operation, user contact information can be stored in a database in advance.

[0034] Before executing step 101, an index relationship based on user number and user contact information can be set first; in step 103, the database can be queried based on each lucky number according to the index relationship to obtain the user contact information corresponding to each lucky number. Only querying the user contact information of each lucky number can avoid querying useless data and reduce memory consumption.

[0035] In order to better understand the present invention, the following describes the embodiments of the present invention in detail by taking the issuance of coupons as an example.

[0036] In the embodiment of the present invention, Figure 2 As shown, the coupon distribution scenario can be simplified and abstracted into extracting lucky numbers from a number pool, which is a set of natural numbers in the interval [0, total number of applications). The extraction step logic is: initialize the extracted number pool list, which stores the extracted non-repeating lucky numbers. When the number of extracted numbers (initialized to 0) is less than the number to be extracted, the single-step extraction logic is looped.

[0037] The single-step extraction logic is: create an instance of the SecureRandom class, then call the nextInt method of this instance, extract a random number, and then determine whether the number has been drawn, that is, whether it is already in the drawn number pool (that is, whether it is the same lucky number). If it has been drawn, draw it again, otherwise save it to the drawn number pool.

[0038] The specific code is as follows:

[0039]

[0040]

[0041] Among them, needSendCount means: the number of samples that need to be drawn.

[0042] applyCount means: total number of applications,

[0043] luckNums means: lucky user data offset set.

[0044] When all lucky numbers are drawn, the correspondence problem between the lucky numbers and the database data begins, that is, finding the user information corresponding to the lucky number.

[0045] In one embodiment, each number in the number pool uniquely corresponds to a record in the corresponding table of the database, so all the data can be regarded as a set of numbers that increase from 0, and each number represents a subscript of the database data, called an offset. For example: if a number 1 is extracted from [0,2), it means that the second data with an offset of 1 is extracted, which is equivalent to a subscript in the array. In specific implementation, the corresponding data can be queried using the limit keyword in the following SQL statement.

[0046] SQL statement: select*from table where clause limit offset,1;

[0047] The meaning of this SQL statement is to query the data with offset offset in the where condition from the table.

[0048] After querying the data, you need to operate on the data itself. Since it is the issuance of coupons, the application record needs to be modified in the future. Using the index or primary key of the data itself during the operation improves the query efficiency of the database and reduces the consumption of the database.

[0049] The embodiment of the present invention mainly aims at randomly and fairly extracting a certain number of application data from a large amount of coupon application data to issue coupons and notify issuance under the premise of low memory and database consumption. In this embodiment, the extraction process is abstracted into a general conceptual model, that is, extracting a certain amount of data from massive data. It gets rid of the shortcomings of traditional solutions such as non-complete fairness, non-complete randomness, complexity, and high resource consumption. At the same time, this conceptual model of the embodiment of the present invention can be used in a variety of business models, such as venue draws, red envelope draws, and all other equal probability model businesses, providing a simple and efficient solution for these businesses.

[0050] Specifically, the main advantages of the embodiments of the present invention are as follows:

[0051] 1. The traditional coupon distribution model is not completely fair, because the application records are stored in ascending chronological order, and in order to prevent the remaining number of coupons at the end of the distribution, the priority application records will actually be drawn in proportion (the remainder plus 1), which is unfair to users who apply later, and each piece of data has only one chance to be drawn after paging query; while the embodiment of the present invention is a one-time extraction, and each piece of data has the same number of extraction opportunities, which ensures the fairness of the extraction.

[0052] 2. Since the lucky users need to be followed up, i.e., to send a winning notification, the traditional solution needs to read the paging quantity records into the memory for operation, which consumes a lot of memory and slows down the running speed. However, the embodiment of the present invention first queries all the quantities and offset values ​​to be issued, avoids querying useless data, and greatly reduces memory consumption. At the same time, since only the offset in the database is operated, the execution efficiency of the database is greatly improved, ensuring low resource consumption in the extraction process.

[0053] 3. The Random class used in the traditional coupon distribution model obtains a pseudo-random sequence by specifying a seed (the default timestamp is the seed), which can be obtained by repeated deduction; however, the SecureRandom class used in the embodiment of the present invention cannot specify a seed. It uses the RNG algorithm to generate a completely safe and random random number through the seed generated by the entropy generated by the random event of the hardware, ensuring the complete randomness of the extraction.

[0054] 4. The implementation of the embodiment of the present invention is simpler and clearer, the amount of code is greatly reduced, and the readability and maintainability of the code are higher.

[0055] Based on similar inventive concepts, an embodiment of the present invention further provides a data processing device. Preferably, the device can be used to implement the process of the above method embodiment.

[0056] Figure 3 is a structural block diagram of the data processing device, such as Figure 3 As shown, the device includes: a data acquisition unit 1, a lucky number generation unit 2 and a notification sending unit 3, wherein:

[0057] The data acquisition unit 1 is used to acquire a plurality of user data, wherein the user data includes: a user number, and the user number is associated with the user contact information.

[0058] The lucky number generating unit 2 is used to perform a predetermined number of traversal operations on multiple user numbers based on a random number generating algorithm to obtain a predetermined number of lucky numbers.

[0059] The notification sending unit 3 is used for sending notification information based on the user contact information corresponding to each lucky number in response to the predetermined number of lucky numbers being different.

[0060] The lucky number generating unit 2 performs a predetermined number of traversal operations on the multiple user numbers obtained by the data obtaining unit 1 to obtain a predetermined number of different lucky numbers. Then, the notification sending unit 3 sends notification information based on the user contact information corresponding to each lucky number. Compared with the existing lucky user extraction scheme based on paging, the embodiment of the present invention extracts each user data the same number of times, thereby ensuring the fairness of the extraction and having better randomness.

[0061] In one embodiment, when there are identical numbers among the predetermined number of lucky numbers, the lucky number generating unit 2 further performs a traversal operation on the plurality of user numbers based on the random number generating algorithm according to the number of identical numbers, so as to obtain the predetermined number of different lucky numbers. Specifically, the lucky number generating unit 2 performs a traversal operation on the plurality of user numbers based on the random number generating algorithm, one less than the number of identical numbers, so as to obtain the lucky number again.

[0062] Specifically, Figure 4 As shown, the lucky number generating unit 2 comprises: a program setting module 21 and a program calling module 22, wherein:

[0063] A program setting module 21 is used to pre-set a secure random program based on a random number generation algorithm;

[0064] The program calling module 22 is used to call the secure random program to perform a predetermined number of traversal operations on the multiple user numbers.

[0065] In one embodiment, the above device further comprises:

[0066] A storage unit, used to pre-store the user contact information in a database;

[0067] An index setting unit, used to set an index relationship based on a user ID and a user contact method;

[0068] The query unit is used to query the database based on each lucky number according to the index relationship to obtain the user contact information corresponding to each lucky number.

[0069] The specific execution process of the above-mentioned units and modules can be found in the description of the above-mentioned method embodiment, which will not be repeated here.

Figure 5 As shown, the electronic device 600 may include a central processor 100 and a memory 140; the memory 140 is coupled to the central processor 100.

[0076] Step 103: In response to the predetermined number of lucky numbers being different, sending notification information based on user contact information corresponding to each lucky number.

Compared with the existing lucky user extraction scheme based on paging, the embodiment of the present invention extracts the same number of times for each user data, which ensures the fairness of the extraction and has better randomness.

The communication module (transmitter / receiver) 110 is coupled to the central processor 100 to provide input signals and receive output signals, which may be the same as the case of a conventional mobile communication terminal.

[0086] Based on different communication technologies, multiple communication modules 110 may be provided in the same electronic device, such as a cellular network module, a Bluetooth module and / or a wireless LAN module. The communication module (transmitter / receiver) 110 is also coupled to a speaker 131 and a microphone 132 via an audio processor 130 to provide an audio output via the speaker 131 and receive an audio input from the microphone 132, thereby realizing a common telecommunication function.
