Referring to fig. 4a, as shown in a cycle time comparison table provided in fig. 4a, if the current time is Tc and is in the second market processing cycle, the first market processing cycle is in the next processing cycle of the current time Tc, the third market processing cycle includes N successive market processing cycles after the first market processing cycle, where N is a positive integer; referring to fig. 4b and 4c, that is, the table shown in fig. 4b is converted to the table shown in fig. 4c, where the time slice in fig. 4b refers to a certain time period, which may be a time period of 5S, 10S, 1min, and the like, and this is not limited herein, the index value in fig. 4c is a unique mark of stock market data, and may be composed of a stock name, such as S1, and a corresponding market processing cycle duration, such as T1, and the data in fig. 4c is a user mark, such as U1, corresponding to a certain stock, and in practical applications, the target stock subscription time subscribed by each reference user may be obtained in fig. 4b, and the market processing cycle is determined by looking up a table of the subscription time; FIG. 4c illustrates a user who needs to synchronize market data of each target stock in a certain market processing period; referring to step E1 in fig. 3, step E1 is a step of clearing user subscription list, which is a task triggered at regular time to clear user subscription list
In the formula, the update time of the user subscription list is Tu, T1 is the duration of the market processing cycle, M is the positive integer, and the stock market server regularly cleans up the invalid user subscription list in order to deal with the situations that the terminal bug and the app are killed.
Therefore, in this example, by adopting the shared data and optimizing the scheme to reduce competition between the read lock and the write lock, the local computing can store and acquire the user subscription list, and the stability, the availability and the real-time performance of the whole market pushing system are improved.
And step 220, updating a pre-configured user subscription list according to the plurality of subscription stock lists, wherein the user subscription list is used for representing users needing market data synchronization in each market processing period of each stock from the stock dimension.
In one possible example, the updating a preconfigured user subscription list from the plurality of subscription stock lists comprises: querying data corresponding to a second market processing cycle in the user subscription list, wherein the second market processing cycle is a market processing cycle before the first market processing cycle; detecting that the data corresponding to the second market processing period is not matched with the plurality of subscription stock lists; and updating data corresponding to the first quotation processing period and a third quotation processing period in the user subscription list according to the plurality of subscription stock lists, wherein the third quotation processing period comprises N continuous quotation periods after the first quotation processing period, and N is a positive integer.
In specific applications, when data corresponding to a first emotion processing cycle and a third emotion processing cycle need to be updated, the values of the N corresponding to the use time and the current moment are extracted from the data set, and then the third emotion processing cycle of the data needs to be updated is determined; it should be understood that the server may have another thread for paying attention to the real-time hot spot information, and if a certain preset keyword (for example, new energy, white spirit, etc., which may cause a large fluctuation of stock quotation after a preset part of keywords appear) appears in the real-time hot spot information, the server queries the preset data set, and if the user does not set a new value of N within the latest preset time, the server may perform an adjustment operation on the value of N, and automatically adjust the value of N available in the current time period in the original data set.
Determining a reference value x according to the number of preset associated words (words representing attention heat) appearing in a preset time period, adjusting N acquired from a data set through the reference value, and obtaining adjusted N
At the same timeThe more the occurrence times of the preset associated words in the time period are, the larger the reference value x is, so that the larger N' is, the longer the push occupation time of the stocks corresponding to the high-heat associated words is.
After the value of N 'is adjusted, the frequency of steps C1 to C3 shown in fig. 3 should be correspondingly adjusted, for example, if the heat of a preset associated word is higher, the reference value x is higher, N' is larger, and the number of times of executing steps C1 to C3 is correspondingly increased.
It should be understood that the user subscription list herein may change according to the user application scenario, for example, after the user switches the software to the background, the system may cancel the subscription by default, and the user subscription list at this time may change accordingly.
Therefore, in this embodiment, the user subscription list is not accumulated continuously, but is updated and adjusted in a preset time period along with the change of the application condition of the terminal device side, and a more frequent pushing step can be performed on the stocks with highly-popular associated words to obtain more real-time quotations and push the more real-time quotations to the user, so that the flexibility and pertinence of the system are improved, and the user experience is improved.
In one possible example, the querying the user subscription list to determine a reference user for which the target stock needs market data synchronization in the first market processing period comprises: and under the condition that the starting time is in a fourth line-condition processing period, querying data corresponding to the first line-condition processing period in the user subscription list to determine the reference user, wherein the fourth line-condition processing period is a next line-condition processing period of the first line-condition processing period.
In order to reduce the competition of the read-write lock on the shared data in the steps B2, C1 and E1, the following method is adopted during implementation: determining a time slice Tn where the user subscription list is located according to the current time Tc; b2, writing the storage data of the time slices of (Tn +1, tn + 2., tn + N), namely updating a pre-configured user subscription list according to the plurality of subscription stock lists; c1, reading the stored data of the time slice (Tn), namely under the condition that the starting time is in a fourth emotion processing period, inquiring data corresponding to the first emotion processing period in the user subscription list to determine the reference user; the step E1 writes (Tn-M) the storage data of the time slice, that is, clear (Tn-M) the data whose writing time is before the M market processing cycle from the user subscription list at intervals of a first preset time, where M is a positive integer, please refer to fig. 4d, where N =3, M =1, specifically, the step B2 starts to write data 4, data 5, and data 6 for 3 consecutive time periods from the time T3, and then the step C1 starts to read from the time T2 and reads from the current time (T3), since the step B2 in the step B2 has no data information, the time T3 in the step C1 in fig. 4d also has no data information, and the data 4 corresponding to the time T3 in the step B2 does not exist until the time T4, the step C1 reads the data 5 and the data 6, and so on, and the description is omitted, and the step E1 writes (clears) the data of the time T2 from the time T4.
It can be seen that, in this example, accessing the user subscription list does not involve network interaction, involves thread lock/process lock, involves three resource locks in the stock market server, where the read-write lock involved is local computation, and the speed of accessing shared data is faster and less time consuming than accessing centralized storage, so as to improve real-time performance and optimize user experience.
And step 230, acquiring the quotation data of the target stock.
In one possible example, the obtaining the market data of the target stock comprises: and acquiring real-time quotation data of the target stock from a stock real-time quotation source, wherein the stock real-time quotation source is used for collecting the quotation data of each stock in the current processing period in trading in a certain quotation processing period.
Wherein the market data includes, but is not limited to: latest price, fluctuation range, 5-grade data of buying and selling (Level-2 market is 10 grades), and the like.
Therefore, in the example, the quotation data in the stock quotation source is pulled in real time, and the quotation data is updated in time, so that the timeliness of stock quotation change is met, the availability of the system is improved, and the user experience is optimized.
In one possible example, the method further comprises: inquiring the user subscription list at preset intervals to acquire data corresponding to a fifth market quotation processing period in the user subscription list, wherein the fifth market quotation processing period is a market quotation processing period before the market quotation processing period at the current moment; according to the data corresponding to the fifth quotation processing period, determining candidate stocks needing quotation data push in the quotation processing period at the current moment and candidate users corresponding to the candidate stocks, and acquiring the real-time quotation data of the candidate stocks from the stock real-time quotation source; and pushing the real-time market data of the candidate stock to the candidate user.
Therefore, in the embodiment, by acquiring the data in the market processing period and correspondingly subscribing the user information, the real-time market pushing user subscription data of the stocks are locally stored, pulled and subscribed at regular time, and the stability, the availability and the real-time performance of the system are improved.
In one possible example, the method further comprises: at the starting time of the fourth market quotation processing period, clearing data written in the user subscription list before M market quotation processing periods of the starting time, wherein M is a positive integer; and if detecting that the corresponding user subscription list data does not exist before the M market processing periods at the starting moment, skipping the step of cleaning the data written in the user subscription list before the M market processing periods at the starting moment.
In step C2 of FIG. 3, the screening process is performed
The current time is Tc, the update time of the user subscription list is Tu, T1 is the market condition processing cycle duration, and N is the positive integer. The stock quotation server obtains the target stock by inquiring the user subscription list, sends the target stock to the stock real-time quotation source and informs the real-time quotation source of the returned target stockAnd sending the quotation data of the target stock to the terminal equipment of the reference user.
As can be seen, in this example, by presetting the screening period, invalid data is reduced, and the robustness and stability of the system are improved.
Referring to step E1 in fig. 3, in addition to the step of clearing the user subscription list data described in step E1, set storage (a storage type) of a local remote dictionary service may be used through a shared data memory, and after data is written, an expire command (time to live command) is used to set timing expiration of the data.
As can be seen, in this example, the data with invalid redundancy can be cleaned up in a plurality of ways, and the robustness and stability of the system are improved.
In one possible example, after the sending the quotation data of the target stock to the terminal device of the reference user, the method further includes: receiving subscription cancellation information sent by the terminal equipment; and deleting the user subscription list data according to the unsubscribe information, and stopping sending the quotation data of the target stock to the terminal equipment of the reference user.
The information for canceling subscription can be from user to cancel subscription, or the device judges that the user cancels subscription by default after the user switches the current stock real-time quotation interface for more than a preset time.
As can be seen, in this example, referring to fig. 3, when the user actively quits from the APP/switches to another service function or the user actively performs a subscription cancellation operation, the step of canceling the subscription is executed by D1, the terminal device sends a subscription cancellation message to the processing timing pull and subscription program in the stock market server, and the timing pull and subscription program executes the step of clearing subscription data by D2, so as to clear data stored in the user subscription list, reduce processing time, and improve operation efficiency.
The embodiment of the application provides a stock quotation pushing method, which is characterized in that a user subscribes data and stores locally through real-time quotation pushing of stocks, the processes of regularly pulling, subscribing and cleaning do not interfere with the flow of pushing the stock quotation, and the stability, the usability and the real-time performance of a system are enhanced.
