Example 1:
the prior art provides various vehicle retrieval methods, generally, a platform server is applied to store collected vehicle data in a MYSQL database, and the data tables in the MYSQL database are traversed in sequence based on limiting conditions in the query process, so that display data are finally determined. For example: MYSQL databases typically include a vehicle table, a city table, a financial schema table, and a financial schema intermediate table; when the user inputs: when the value-added tax of the Shenyang Audi vehicle 2015 is met, the application platform server sequentially traverses a plurality of related tables to finally obtain display data, and in the process that the application platform server traverses the related tables, the application platform server is in a waiting state for a long time, so that the utilization rate of resources such as system bandwidth, a database and the like is reduced.
In order to solve the above technical problems, a first aspect of an embodiment of the present application shows a processing system for switching data sources;
referring to fig. 1-1, and to fig. 1-2, the system includes:
an application platform server 31, a data storage server 32 connected to the application platform server 31, wherein the data storage server 32 is disposed inside the application platform server 31 or independently disposed, a development server 34 connected to the application platform server 31, and the application platform server 31 is connected to a terminal 33 through the internet;
the terminal 33 is used for displaying information;
the terminal 33 shown in the embodiment of the present application is a device located at the outermost periphery of the network in the computer network, and is mainly used for inputting user information, outputting processing results, and the like. The prior art shows mobile terminals such as: the mobile phone and the PAD are both in the protection scope of the embodiment of the application.

the application platform server shown in the embodiments of the present application requests a connection to a GRPC based on the TCP/IP protocol that spans the transport and application layers in the OSI network communication model. Compared with the traditional application platform server traversing MYSQL database based on the HTTP protocol, the method has faster data transmission speed and improves the operation efficiency of the system.
When the data source of the ES database fails, the data switch is directly switched to the MYSQL database, and the application platform server directly traverses the MYSQL database to search out the display content matched with the query request.

If the error rate of the ES database in unit time exceeds the monitoring rule, the direct data switch is switched to the MYSQL database. And directly traversing the MYSQL database, and simultaneously, sending a mail to a development server, wherein the development server repairs the ES database or checks the data in the ES database. When the repair of the ES database or the inspection of the data in the ES database is completed, the development server sends a repair completion instruction to the application platform server, and at this time, the application platform server switches the data switch to the ES database, and the application platform server continues to traverse the ES database.
For example:
the user inquires 'Audi A6, 2015 value-added tax', the system defaults to traverse the ES database, when the 5 th data is found, the application platform server feeds back the display interface 'no record', the data switch is switched to the MYSQL database, and the application platform server continues to traverse the MYSQL database based on 'Audi A6, 2015 value-added tax'. When the 6 th data is detected, the data switch is switched to the ES database, the application platform server continuously traverses the ES database based on the 'Audi A6, 2015 value added tax', meanwhile, the application platform server monitors the error rate of the ES database in real time, for example, when the 203 th data is searched, the error rate of the ES database in 1 minute is 100 times, at the moment, the error rate of the ES database in unit time exceeds the monitoring rule, the application platform database sends mails to the development server, and the development server repairs the ES database or verifies the data in the ES database. When the repair of the ES database is finished or the data in the ES database is checked, the development server sends a repair finishing instruction to the application platform server, and at the moment, the application platform server switches the data switch to the ES database and the application platform server continuously traverses the ES database.
It is noted that, in the process of repairing the ES database by the development service or verifying the data in the ES database, the data switch of the application platform database is directly switched to the MYSQL database, and when the application platform server receives the repair completion instruction sent by the development server, the data switch is continuously switched to the ES database.

a service record of a certain vehicle may be queried.
Or may be a query for additional information about a vehicle or class of vehicles, including additional fees paid by the user during the purchase of the vehicle, e.g. value-added tax, insurance … …

S102, traversing a database based on the query request, and determining display content, wherein the database comprises: ES database, and MYSQL database;
in the actual traversing process, the system traverses the ES database by default, when the data source of the ES database fails, the data switch is directly switched to the MYSQL database, and the application platform server directly traverses the MYSQL database to search out the display content matched with the query request.

Meanwhile, the ES database is based on the TCP/IP protocol, which spans the transport layer and the application layer in the OSI network communication model. Compared with the traditional application platform server traversing MYSQL database based on the HTTP protocol, the method has faster data transmission speed and improves the operation efficiency of the system.
Files in the ES database are stored in a binary form, so that compared with a complex MYSQL storage mode, the storage speed is faster; meanwhile, the complexity of data processing logic is low, the complex MYSQL statement is stored in a binary form, the problem that the MYSQL statement needs to cache data for multiple times when data change is effectively avoided, memory is saved, the running load of the system is not increased, and the running efficiency of the system is improved.

Meanwhile, when the data source of the ES database fails, the data switch is directly switched to the MYSQL database, and the application platform server directly traverses the MYSQL database to search out the display content matched with the query request.
The method effectively avoids the problem of failure in acquiring data when the data source fails, and meanwhile, the MYSQL database and the ES database are mutually backed up, so that the performance availability is enhanced.
Example 3:
in order to further shorten the method shown in the embodiment of the present application, in the data searching process, the waiting time of the application platform server is shortened, and the situation that the application platform server is in a waiting state for a long time because the application platform server traverses the wrong database in the searching process is avoided, in which the embodiment of the present application shows a switching method of an ES database and a MYSQL database, specifically, please refer to fig. 4;
embodiment 3 has similar steps to the technical solution shown in embodiment 2, the only difference being that the step of traversing the database in step S102 in the technical solution shown in embodiment 2 comprises the following steps:

s10212, judging whether the ES database runs normally or not;
judging whether the ES database runs normally or not, wherein the ES database comprises the following steps;

If the system returns a status code in the process of traversing the ES database, proving that the ES database operates abnormally;
if the system returns a prompt in the process of traversing the ES database, proving that the ES database operates abnormally;
in the actual traversal process, the abnormal operation of the ES database can be judged even if the traversal result does not return the correct display result, and the abnormal states are not listed one by one because of limited space.
S10213, traversing the ES database if the ES database operates normally;
s10214, traversing the MYSQL database if the ES database runs abnormally.
The embodiment of the application shows a switching process of an ES database and a MYSQL database. The system directly traverses the ES data by default, when the data source of the ES database fails, the data switch is directly switched to the MYSQL database, and the application platform server directly traverses the MYSQL database to search out the display content matched with the query request.

Meanwhile, the MYSQL database and the ES database are mutually backed up, so that the performance availability is enhanced.
Example 4:
if the ES database is frequently abnormal in operation, the ES database is preferably traversed, and when the ES database is abnormal in operation, the MYSQL database is traversed again, which clearly increases the selection time of the system, in order to solve the above problems, the embodiment of the present application shows a monitoring scheme of the ES database, and specifically, please refer to fig. 5:
embodiment 4 has similar steps to the technical solution shown in embodiment 2, and the only difference is that the step of traversing the database in step S102 in the technical solution shown in embodiment 2 includes the following steps, specifically, please refer to fig. 5:
s10221, starting a monitoring service, and monitoring the running condition of the ES database in real time;
in the inquiring process, a monitoring service is started, and the monitoring service is used for monitoring the running condition of the ES database in real time, wherein the running condition comprises the detection of the error rate of the ES database in unit time.
S10222, judging whether the running condition of the ES database accords with a monitoring rule;
the detection rule is to allow the ES database to be online with error rate in unit time;
for example, a calculation rule of a specific monitoring rule, for example, ES database 1s may provide 200 search results, MYSQL database 1s may provide 150 search results;
if 20 running anomalies occur in the ES database in the next 1s, the search results provided by traversing MYSQL directly in 1s are more than those provided by traversing the ES database first, such as the search results provided by traversing the MYSQL database after the running anomalies of the ES database are found.
At this time, 20 times/s are used as monitoring rules;
it should be noted that, in the embodiment of the present application, only an exemplary calculation scheme describing a monitoring rule is described, in the practical application process, where it can be determined that the search result provided by directly traversing MYSQL in a unit time is more than that provided by traversing the ES database first, for example, the monitoring rule of finding that the ES database is abnormal in operation and then traversing the search result provided by traversing the MYSQL database is within the protection range of the method shown in the embodiment of the present application, again, because of limited space, the method is not listed one by one.
S10223, traversing the ES database if the monitoring rule is met;
s10224, if the monitoring rule is not met, traversing the MYSQL database and repairing the ES database.
In the repair process of the ES database, the data switch is directly switched to the MYSQL database, during which the application platform server directly traverses the MYSQL database, and when the ES database is repaired, the data switch is switched to the ES database.
For example, if 1000 data are searched, the error rate of the ES database is found to have exceeded the monitoring rule during the 500 th data search, at this time, the data switch is directly switched to the MYSQL database, the ES database is repaired during the 700 th data search, and the system defaults to search the MYSQL database during both the 500 th data search and the 700 th data search.
According to the scheme shown in the embodiment of the application, the system defaults to traverse the MYSQL database in the abnormal operation process of the ES database, so that the database with frequent traversal errors of the application platform server is effectively avoided, the time waste in the data switch switching process is shortened, the waiting time of the application platform server is further shortened, and the utilization rate of resources such as system bandwidth, the database and the like is improved.
Example 5:
in order to enhance the connection between the application platform server and the development server, the embodiment of the application shows a connection method of an application platform, and specifically, please refer to fig. 6:
embodiment 5 has similar steps to the technical solution shown in embodiment 4, with the only difference that the step of repairing the ES database in step S10224 in the technical solution shown in embodiment 2 includes the following steps:
s102241, sending a repair request for repairing the ES database to a development server;
s102242 receives a repair completion instruction sent by the development server, and enables the ES database.
For example, the user queries "Audi A6, 2015 value-added tax" in real time through a processing system of data source switching, the system traverses the ES database by default, when the 5 th data is found, the application platform server feeds back a display interface "no record of the record", the data switch switches to the MYSQL database, and the application platform server continues to traverse the MYSQL database based on "Audi A6, 2015 value-added tax". When the 6 th data is detected, the data switch is switched to the ES database, the application platform server continuously traverses the ES database based on the 'Audi A6, 2015 value added tax', meanwhile, the application platform server monitors the error rate of the ES database in real time, for example, when the 203 th data is searched, the error rate of the ES database in 1 minute is 100 times, at the moment, the error rate of the ES database in unit time exceeds the monitoring rule, the application platform database sends mails to the development server, and the development server repairs the ES database or verifies the data in the ES database. When the repair of the ES database or the inspection of the data in the ES database is completed, the development server sends a repair completion instruction to the application platform server, and at this time, the application platform server switches the data switch to the ES database, and the application platform server continues to traverse the ES database.
According to the method, when the MYSQL runs abnormally, a repair request is directly sent to the development server, when the repair of the ES database is completed, a repair completion instruction is directly sent to the application platform server, the data switch is directly regulated to the ES database, the direct work close connection of each server is effectively ensured, the coordination time of personnel in each middle department is shortened, the waiting time of the application platform server is further shortened, and the utilization rate of resources such as system bandwidth, databases and the like is improved.
Example 6:
