Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Since the first operation is extremely time-consuming, it is full of all business threads, and there are no available threads to the data caller. Thus, thread pool exhaustion may be induced, and alert information may be sent to the data caller, resulting in a particularly poor experience for the data caller.
Sometimes, when a service is online, a system of a data calling party feeds back an alarm message, and some services are open to the outside and are not good for merchant experience related to service calling.
In order to solve the problem that the time consumption of the first operation is extremely long, the following technical scheme in the embodiment of the invention can be adopted.
Referring to fig. 1, fig. 1 is a schematic diagram of a main flow of a method for providing a data service according to an embodiment of the present invention, by constructing a virtual data request, a link with a data provider is established to provide the data service. As shown in fig. 1, the method specifically comprises the following steps:
s101, monitoring that an application system for providing services externally is started, and acquiring an array of virtual hash sub-library sub-table main keys according to a routing forwarding rule.
In the embodiment of the invention, the time consumption of the first operation is considered to be particularly long, because a link with a data provider needs to be established in the process of the first operation. Then, the virtual data request can be used for establishing the link with the data provider, and under the condition that the actual data request is received, the data service can be directly provided without establishing the link with the data provider, so that the time consumption of the first operation can be reduced.
Specifically, the technical solution in the embodiment of the present invention may be executed after the application system is completely started. Moreover, the technical scheme in the embodiment of the invention is only executed once after the application system is completely started, and the operation with the application system is executed asynchronously. In this way, a link is established with the data provider through the virtual data request without affecting the normal use of the application system.
In the embodiment of the present invention, an application system may be understood as an application software, that is, an application software that provides services externally.
In one embodiment of the present invention, when an application system for providing external services is started, the method triggers the acquisition of an array of virtual hash score table primary keys according to a routing forwarding rule. Wherein, the start-up may include a first start-up and a restart.
As an example, an event may be triggered after an application system has been started, and when the trigger event is monitored, it is known that the application system has been started for the first time.
In the embodiment of the invention, the routing forwarding rule can be preset. Specifically, the routing forwarding rule is a rule for selecting an optimal path according to information in a routing table and forwarding data. Then, an array of virtual hash score table primary keys may be obtained based on the routing forwarding rules. The array is not an array related to the actual data request, but an array obtained by carrying out hash operation on a virtual sub-base sub-table main key.
The virtual data request can be constructed using an array of virtual hash partition table primary keys.
S102, establishing an entry parameter value of an instance method according to the array of the virtual hash partition table main key and the entry parameter type of the instance.
Methods involving the instance and the entry values of the instance are required in constructing the virtual data request. A class is an abstract template, such as a Student class. And an instance is a specific object created from classes, each having the same method.
In the embodiment of the invention, the designated examples and the methods of the examples are acquired through dynamic configuration files. That is, the instances and methods of the instances are stored in a configuration file, and the configuration file is dynamic. That is, the configuration file includes instances and methods of the instances that are not one-to-one.
In one embodiment of the invention, the configuration file includes an instance of the database connection operation and a method of the instance of the database connection operation, and a method of the instance of the middleware and the instance of the middleware.
That is, for the case where the data provider is a database, the configuration file includes an instance of the database connection operation and a method of the instance of the database connection operation. In this way, a link is established with the database.
For the case where the data provider is a middleware, the configuration file includes an instance of the middleware and a method of the instance of the middleware. In this way, a link is established with the middleware. Data can be interacted with other databases through middleware.
In an embodiment of the present invention, a configuration file includes a plurality of instances and methods of the instances. The method parameters of the instance that needs to be initialized are selected based on the actual requirements. The method of the instance can be a query operation or a newly developed operation, etc.
In an embodiment of the invention, the data provider comprises a database and/or middleware. That is, the technical solution of the embodiment of the present invention is not only applicable to databases, but also to middleware. As one example, middleware may be JDDL, ES middleware, redis cache, and the like. JDDL is a middleware for seed-pool-table separation. ElasticSearch (ES) is a highly extended distributed search server based on Lucene.
Referring to fig. 2, fig. 2 is a schematic flow chart of constructing a virtual data request according to an embodiment of the present invention, and specifically includes the following steps:
s201, initializing a parameter array.
An initialization operation is required before the parameterization of the method of the build instance.
As an example, a set of parameter arrays may be initialized according to the number of parameters of the method of the instance, where the parameter types in the parameter arrays need to conform to the method entry types of the instance.
That is, initializing a set of parameter arrays, wherein the number of parameters is the same as that of the example method; the parameter type is the same as the parameter type of the method of the instance. The purpose of the initialization is to build the entry value of the instance method.
S202, establishing an entry parameter of the method of the instance according to the array of the virtual hash sub-table main key and the initialized parameter array.
The number of parameters of the initialized parameter array is the same as that of the method of the example, and the parameter type of the initialized parameter array is the same as that of the method of the example.
The method for constructing an instance is based on an array of virtual hash index primary keys and an initialized array of parameters. In the case of constructing multiple input parameter values, the array of the primary keys and an initialized parameter array may be divided according to a circular virtual hash score table.
Thus, according to the technical solution in the embodiment of fig. 2, the parameter values of the method of the embodiment are constructed.
In one embodiment of the invention, a virtual data request is constructed, the method of the instance can be executed by a reflection method, and the input parameter value of the method is input to construct the virtual data request.
Reflection is a computer processing method. There is the ability for a program to access, detect and modify its own state or behavior. Objects of the type of the wrapper set can be provided. All resources related to the instance can be obtained through a reflection method.
S103, combining the parameter entering value of the method, executing the method of the instance, and constructing the virtual data request.
Thus, the instance method type, and the instance method's parametrics are all known, then a virtual data request may be constructed. That is, the method of the instance is executed in combination with the entry parameter of the method of the instance, and a virtual data request is constructed.
S104, submitting the virtual data request to a thread pool, and establishing a link with a data provider to provide data service.
As one example, a set of thread pools is initialized and virtual data requests for each execution build may be committed to the thread pools. The default number of thread pools may be preset, for example: the default number of thread pools is 100.
In embodiments of the present invention, virtual data requests may be synchronously submitted to a thread pool or asynchronously submitted to a thread pool. Because of synchronously submitting the virtual data requests, the number of the virtual data requests in the thread pool is large, and the normal operation of the main thread can be influenced.
Asynchronous submission of virtual data requests, i.e., asynchronous submission of virtual data requests into a thread pool, may then be employed to establish links with data providers to improve efficiency.
Virtual data requests are asynchronously submitted to the thread pool. The virtual data request is executed in a task queue of the thread pool, and the task is executed asynchronously for the main thread, and does not block the continued execution of the main thread. And the normal operation of the main thread is further ensured because the main thread and a plurality of virtual data requests do not need to be processed at the same time.
The virtual data request is submitted to the thread pool, and the virtual data request is executed in a task queue of the thread pool to establish a link with the data provider.
The virtual data request is established by a method of executing class examples in which a link is established with a data provider in an interaction with the data provider.
In one embodiment of the invention, a data service is provided based on a link with a data provider in response to an actual data request. .
After receiving the actual data request, the service is released online to provide the data service by directly adopting a link with the data provider in order to process the actual data request. Wherein the actual data request corresponds to the same instance as the virtual data request.
It is understood that the virtual data request is established based on an instance-based approach. After establishing a link with a data provider according to the virtual data request, for the actual data request of the method of the same instance as the virtual data request, the service release can be online without establishing a link with the data provider, so that the time consumption of the first operation is reduced.
In the above embodiment, the application system for monitoring the external service is started, and the array of the virtual hash sub-library sub-table main key is obtained according to the routing forwarding rule; establishing an entry parameter value of an instance method according to an array of the Ha Xifen base sub-table main key and the entry parameter type of the instance; executing an instance method by combining the parameter entering value of the method, and constructing a virtual data request; the virtual data request is submitted to a thread pool, and a link is established with a data provider to provide a data service. Since the link with the data provider is established in advance, the data service can be directly provided, and thus the time consumption of the first operation can be reduced.
The virtual data request constructed by the method is sent to a data provider, so that an application system can be preheated. And the service quality is improved. The first time an actual data request is sent, the service user is not aware of the actual data request, and the service user is also not aware of the merchant side. The method solves the problem of unstable service, such as overtime, and the like, which is caused by the prior occurrence of thread pool exhaustion. And the experience of a merchant terminal and a service user is greatly improved.
Referring to fig. 3, fig. 3 is a schematic diagram of a conventional flow of providing a data service. It is understood that the application system may receive the actual data request. An application system may be understood as software that provides data services externally through actual data requests.
The application system starts to initialize. In response to an actual data request, the service issues an online. In the process of service release online, a link with a data provider is established, and then service release online is realized.
In fig. 3, the first operation is particularly time consuming, since a link to the data provider needs to be established.
Referring to fig. 4, fig. 4 is a schematic flow chart of providing a data service according to an embodiment of the present invention, and the technical solution of fig. 4 is different from that of fig. 3 in that a preheating step is added.
The application system in fig. 4 may adopt the technical solution in the embodiment of the present invention. The application system starts to initialize.
And according to the array of the Ha Xifen base sub-table main key and the method parameter entry type of the instance, constructing the parameter entry value of the method of the instance, and further constructing the virtual data request.
In the process of preheating, the virtual data request is submitted to a thread pool, and a link with a data provider is established.
And further, in the process of service release online, responding to the actual data request, and providing data service based on the link with the data provider so as to realize service release online.
As one example, the database is accessed through JDDL middleware client. The database is divided into database and table, and the redis cache is used in the application system as a method for improving the query performance. By implementing the scheme in the embodiment of the invention in the application system, the time consumption of the first operation can be reduced.
In the above-described embodiment, the link with each data provider is established in advance. When the application system is started, only a link pool of the database is initialized, no links are actually created with each data provider, and no actual data interaction occurs. It may be necessary to establish a link with each data provider when accessing the actual data request.
Establishing a link with each data provider is actually time-consuming, simulating an actual data request through a virtual data request, establishing a link with the data provider in advance, performing data interaction, enabling the application system just started to reach the same state as the running application system, and then issuing the application system online.
Referring to fig. 5, fig. 5 is a schematic diagram of a main structure of an apparatus for providing a data service according to an embodiment of the present invention, the apparatus for providing a data service may implement a method for providing a data service, and as shown in fig. 5, the apparatus for providing a data service specifically includes:

In one embodiment of the invention, the actual data request corresponds to the same instance of the virtual data request.

In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The described modules may also be provided in a processor, for example, as: a processor includes an acquisition module, a parameter module, a request module, a setup module, and a service module. The names of these modules do not in some cases limit the unit itself, for example, the acquisition module may also be described as "an array for acquiring a virtual hash score table primary key according to the route forwarding rule".
As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be present alone without being fitted into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to include:
monitoring that an application system for providing services externally is started, and acquiring an array of virtual hash sub-library sub-table main keys according to a routing forwarding rule;
establishing a parameter entering value of a method of an instance according to the array of the Ha Xifen base sub-table main key and the parameter entering type of the method of the instance;
executing the method of the instance by combining the parameter entering value of the method, and constructing a virtual data request;
and submitting the virtual data request to a thread pool, and establishing a link with a data provider to provide data service.
According to the technical scheme of the embodiment of the invention, the application system for providing the service to the outside is monitored to be started, and the array of the virtual hash sub-library sub-table main key is obtained according to the routing forwarding rule; establishing an entry parameter value of an instance method according to an array of the Ha Xifen base sub-table main key and the entry parameter type of the instance; executing an instance method by combining the parameter entering value of the method, and constructing a virtual data request; the virtual data request is submitted to a thread pool, and a link is established with a data provider to provide a data service. Since the data service can be directly provided without establishing a connection with the data provider after receiving the actual data request, the time consumption of the first operation can be reduced.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
