In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
In some embodiments of the present application, please refer to fig. 1, and fig. 1 is a flowchart illustrating a basic method of a data downloading method according to an embodiment of the present application. The details are as follows:
in step S101, data downloading request data sent by a user side is received, where the data downloading request includes data requirement information.
In this embodiment, the user may send a data downloading request to the downloading service of the data service platform by using the user side to request to download the required data. The data downloading request contains data requirement information, and the data to be downloaded can be screened out from a database of the data service platform according to the requirement information. Taking a financial data service platform as an example, the database of the platform contains various types of market data such as stock market data, futures market data, interest rate market data, credit market data, exchange rate market data and the like, and each type of market data contains various indexes. In this embodiment, the download-required information may be data type information, data index information, date condition, and the like. For example, if the download request information includes three items of information, i.e., a stock code a, a fluctuation index, and quarter 2 in 2020, the data required by the user at this time is the fluctuation data of the stock code a each day in the period from 4/1/2020 to 6/30/2020.
In step S102, a data quantity value corresponding to the data requested to be downloaded by the data download request is calculated according to the data requirement information by combining with a database.
In this embodiment, a large amount of data resources are stored in the database of the data service platform, and in this embodiment, data screening may be performed according to the obtained data demand information to obtain data that the user demands for downloading. Specifically, a corresponding data list is generated in the database according to the data demand information, and then the data amount occupied by the generated data list in the database is calculated in an SQL statement query mode, so that the data amount value corresponding to the data requested to be downloaded by the user side is obtained. The data quantity value represents the size of the data requested to be downloaded by the user terminal.
In step S103, a waiting queue matching the data download request is selected from a preset waiting queue configuration table according to the data quantity value, and the data download request is added to the waiting queue for queuing and data download processing.
In this embodiment, a waiting queue configuration table is configured in the download service of the data service platform, the configuration table at least includes two or more waiting queues, and the data download request can be added to the waiting queue for queuing and data download processing by selecting a waiting queue matching the data download request from a preset waiting queue configuration table according to the data quantity value.
In some implementations, referring to fig. 2, fig. 2 is a flowchart illustrating a method for selecting a waiting queue according to a data size in a data downloading method according to an embodiment of the present disclosure. The details are as follows:
in step S201, according to the data quantity value traversing the data quantity application range configured for the waiting queue in the preset waiting configuration table, determining whether the data quantity value falls within the data quantity application range;
in step S202, if the data amount value falls within the data amount application range, it is determined that the waiting queue corresponding to the data amount application range is a waiting queue matched with the data download request.
In this embodiment, in the preset waiting queue configuration table, each waiting queue may be provided with a corresponding applicable data size range, for example, the data size range correspondingly used by the first waiting queue is not more than 1M, the data size range correspondingly used by the second waiting queue is 1M < X not more than 10M, and the data size range correspondingly used by the third waiting queue is more than 10M, where M is a unit of data size. In this embodiment, the data amount value is calculated according to step S102, and a corresponding waiting queue may be selected from the preset waiting queue configuration table according to the data amount range in which the data amount value falls, for example, the data amount value is less than 1M, and the waiting queue selected from the preset waiting queue configuration table and corresponding to the data amount value is the first waiting queue. And after the waiting queue corresponding to the data quantity value is obtained, adding the data downloading request to the tail of the selected waiting queue for queuing. And sequentially polling the first data downloading request queued in the waiting queue through the server to perform data downloading processing.
The data downloading method provided by the embodiment flexibly separates the data downloading request with large downloading data volume and the data downloading request with small downloading data volume into different waiting queues for queuing and downloading by adding the data downloading request into different waiting queues, thereby avoiding the condition that the queuing and waiting time of the data downloading request with small downloading data volume is overlong when the data downloading request with small downloading data volume is arranged behind the data downloading request with large downloading data volume, and having good flexibility. And under the condition of high concurrency of data downloading requests, each waiting queue can be used for carrying out data downloading service in a division manner, so that the stability of the server is effectively ensured.
Referring to fig. 3, in some embodiments of the present application, fig. 3 is a schematic flow chart illustrating another method for selecting a wait queue according to a data size value in a data downloading method according to an embodiment of the present application. The details are as follows:
in step S301, a load amount of each waiting queue in the preset waiting queue configuration table is obtained, where the load amount is represented by a sum of predicted time values consumed for data downloading processing corresponding to all data downloading requests queued in the waiting queue;
in step S302, determining an idle time node corresponding to the waiting queue according to the load of the waiting queue, and sorting each waiting queue in the preset waiting queue configuration table according to the order of the idle time nodes of the waiting queue;
in step S303, the waiting queue with the first rank is selected as the waiting queue matched with the data download request, and the data download request is added to the waiting queue matched with the data download request for queuing and data download processing.
In this embodiment, a matched waiting queue may be selected for the data download request sent by the current receiving user end according to the load condition of the current waiting queue of the download service of the data service platform, so as to solve the problem that the user has too long queuing waiting time, and ensure that the user can download the data desired by the user as fast as possible under the condition of high concurrency. In this embodiment, the load capacity of each waiting queue is obtained first, and the load capacity is characterized by the sum of the predicted time values consumed by the data downloading process corresponding to all the data downloading requests queued in the waiting queue. For example, 5 data download requests are queued in the current first wait queue, and the predicted time consumed for data download processing corresponding to each data download request is 3 seconds, 2 seconds, 1 second, and 2 seconds. At this time, the load amount of the first wait queue is obtained as 3+3+2+1+2 — 11 seconds. And determining an idle time node corresponding to the waiting queue according to the load capacity of the waiting queue, for example, the load capacity of the first waiting queue is 11 seconds, that is, the current time plus 11 seconds is the idle time node of the first waiting queue. Sequencing each waiting queue in the preset waiting queue configuration table according to the sequence of the idle time nodes of the waiting queue, for example, there are 3 waiting queues in the waiting queue configuration table, which are respectively a first waiting queue, a second waiting queue and a third waiting queue, and the load amounts of the 3 waiting queues in the waiting queue configuration table obtained according to the above are respectively 11 seconds, 5 seconds and 20 seconds, at this time, sequencing each waiting queue in the preset waiting queue configuration table according to the sequence of the idle time nodes to obtain a sequencing result as follows: a second wait queue, a first wait queue, a third wait queue. Therefore, the waiting queue with the first sequencing is selected as the waiting queue matched with the currently received data downloading request sent by the user terminal, and the data downloading request is added into the second waiting queue for queuing and data downloading processing.
In some embodiments of the present application, please refer to fig. 4, and fig. 4 is a schematic flowchart illustrating a method for obtaining downloaded data based on a cache in a data downloading method provided in the embodiments of the present application. The details are as follows:
in step S401, querying whether a preset buffer contains buffer data matched with the data download request;
in step S402, if the preset buffer contains the cache data matching with the data downloading request, the cache data is directly fed back to the user side as the downloading result.
In this embodiment, a buffer is configured in the data service platform, and is used for buffering data requested to be downloaded by all users on the same day. After the server sequentially polls the first data downloading request queued in the waiting queue for data downloading processing, the downloaded data and the data requirement information corresponding to the data downloading request are cached in the buffer. In this embodiment, after the download service of the data service platform newly receives data download request data sent by a user, it may first determine whether the cache data matches the data download request by querying the cache, and if before the user sends the data download request, other users have sent data download requests to download data corresponding to the same data requirement information, the cache data corresponding to the data requirement information will be retained in the cache. Therefore, by querying the buffer, it can be known whether other users have downloaded the same data with the same data demand information on the current day, and if so, it is indicated that the buffer retains the buffer data corresponding to the data demand information. At this time, according to the data download request sent by the current user side, the cache data matched with the data download request can be directly obtained from the cache, and then the obtained cache data can be directly fed back to the user side as a download result. Therefore, the time for the user side to obtain the download data can be saved, and the load of the download service is reduced.
In some embodiments of the present application, please refer to fig. 5, and fig. 5 is a flowchart illustrating a method for selecting a waiting queue from a preset waiting queue configuration table in a data downloading method according to the embodiments of the present application. The details are as follows:
in step S501, it is determined whether an idle waiting queue exists in the waiting queue in the preset waiting queue configuration table, where the idle waiting queue is a waiting queue without a data download request;
in step S502, if yes, the data download request is added to the idle waiting queue for data download processing.
In this embodiment, the download service of the data service platform may further perform real-time load monitoring on each waiting queue in the waiting queue configuration table configured with the download service, and obtain a load amount of each waiting queue, where the load amount is represented by the number of data download requests. In the configuration table, the idle waiting queue is a waiting queue without a data downloading request. If no data download request is currently in the waiting queue, the waiting queue is marked as an idle waiting queue until the waiting queue is added with the data download request, and then the mark of the idle waiting queue is cancelled. Therefore, whether an idle waiting queue exists in the waiting queue in the preset waiting queue configuration table can be judged through real-time load monitoring. If the idle waiting queue exists in the configuration table, the received data downloading request sent by the user side is preferentially added to the idle waiting queue to directly perform data downloading processing. Therefore, the waiting queue with a large load can be helped to reduce the load, the waiting queue can be flexibly selected, and the time consumption of a user for downloading data is reduced.
In some embodiments of the present application, please refer to fig. 6, and fig. 6 is a flowchart illustrating a method for adjusting a queuing position of a data download request in a waiting queue in a data download method according to the embodiment of the present application. The details are as follows:
in step S601, frequency for waking up a user to download an interface is obtained;
in step S602, a queuing position of the data download request sent by the user side in the waiting queue is adjusted according to a preset frequency queuing mechanism and the frequency.
In this embodiment, after the data downloading request is added to the waiting queue for queuing, the data required by the user may be preferentially downloaded for the user who needs to download the data urgently by identifying the urgent degree of the user for the data downloading request, so as to improve the user satisfaction. In this embodiment, the frequency for waking up the downloading interface of the user side is obtained by monitoring, specifically, the user may wake up the downloading interface of the user side by executing the operation of checking the progress of downloading the message at the user side, and if the user executes the operation of checking the progress of downloading the message more frequently, it indicates that the user has a higher urgency for the requirement of downloading data. At this time, the queuing position of the data download request sent by the user side in the waiting queue can be determined according to the preset frequency queuing mechanism and the obtained frequency for waking up the user side download interface, so that the data download processing is preferentially arranged according to the data download request sent by the user side. In some specific implementations, in the frequency queuing mechanism, an adjustment rule may be set for a plurality of data download requests queued in a waiting queue, and when the frequency of the wake-up operation of a later set data download request within a preset time period exceeds a preset threshold and all data download requests of a previous set do not have a wake-up operation, the queuing position of the later set data download request may be preferentially adjusted to the first position for preferential download at this time. And further dynamically adjusting the queuing position of each data downloading request in the waiting queue according to the adjustment rule. For example, 10 data download requests in the waiting queue are queued, the 5 th data download request is monitored to be woken up 3 times (assuming that the preset threshold is set to be 2 times), and the previous 1 st to 4 th data download requests are not monitored to be woken up, at this time, the queuing position of the 5 th data download request can be adjusted to be 1 st, and the original 1 st to 4 th data download requests are all backed off by 1 position, thereby realizing that the user side which needs to download data urgently downloads data preferentially. In other specific implementations, the frequency queuing rule is not limited to the adjustment rule set above, and can be reasonably set according to actual requirements. For example, based on the adjustment rule, the dynamically adjusted data download request is waken up to not participate in the adjustment of the queuing position for wakening up other subsequent data download requests. For example, if the queuing position of the 5 th data download request is adjusted to 1 st, the 7 th data download request in the waiting queue is also monitored to have 3 awakenings, but the 5 th data download request is not downloaded yet and is still waiting for the first bit, then the 7 th data download request can only adjust its queuing position to 2 nd bit, but does not adjust its queuing position to 1 st bit, and the 1 st bit is still the original 5 th data download request. Therefore, by formulating a frequency queuing rule, the queuing position of the data downloading request in the waiting queue is dynamically adjusted according to the urgent degree of the user for downloading the data, the data required by the user who needs to download the data urgently is downloaded preferentially, the data downloading time of the user who needs to download the data urgently is reduced, and the satisfaction degree of the user is improved. In some specific implementations, step S301 may be further combined, and meanwhile, whether an idle waiting queue exists in the configuration table is monitored, after the frequency for waking up the user side to download the interface is obtained, if the frequency meets the preset threshold and it is monitored that the idle waiting queue exists in the configuration table, the data download request whose frequency meets the preset threshold may be added to the idle waiting queue to directly perform data download processing, and the data download request is deleted from the original waiting queue.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
