Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Currently, the corresponding data format of different business is not quite similar by taking government system as an example, relevant database is utilized
Data are stored, when facing the business development of government system, are solved frequently with two ways, one is by business number
It is defined as very big table according to table, comprising the field that all business need, another kind is that business datum is split into multiple tables, often
Those of kind of business datum association table safeguarded using additional table, store using relevant database it is safer, but
It is the business datum for magnanimity, either query statistic or updating maintenance all become more and more difficult, and relational data
Library expansibility is poor, does not support read and write abruption, government system slower for the inquiry response speed of user.It is of the invention based on this
The method, apparatus and electronic equipment for a kind of promotion data query performance that embodiment provides, can be applied to carry out pipe to data
In the scene of reason.
For convenient for understanding the present embodiment, first to a kind of promotion data query disclosed in the embodiment of the present invention
The method of energy describes in detail.
The flow chart of the method for a kind of promotion data query performance shown in Figure 1, wherein this method specific steps are such as
Under:
Step S102 obtains user data；
Step S104 changes the progress additions and deletions of preset relation type database according to user data and looks into operation；
It is stored using mass users data of the relevant database to generation, according to user data to relational data
The basic operation that the data saved in library are increased, deleted, modified, searched etc..
Step S106 obtains the lookup record of user；
Step S108 is recorded according to searching, and high-frequency data is determined from relevant database；
High-frequency data is updated in the MongoDB database pre-established by step S110.
In order to reduce redundant data, also for query performance is promoted, will be saved in data in MongoDB database into
Row, which extracts, determines high-frequency data, can record according to searching, obtain the number that each data in relevant database are searched；
The data for reaching preset times by lookup number are determined as high-frequency data.
Processing is carried out to high-frequency data to be saved in MongoDB database, in inquiry, utilizes MongoDB database pair
The requests such as inquiry, list displaying, the statistics of user quickly respond, can also be by configuring, by source for the column of displaying
It is combined in the content of each field, improves the readability for showing list, then existed for further detailed content search
It is executed in relevant database, greatly promotes data query performance, also improve the experience sense of user.
By taking government system as an example, for city-level unit user, with it, about 1500 business of processing, every business are related to daily
About 5 tables, every business generate record about 15, then one day recorded amounts generated also has about 20,000, are related to about 25
Different tables constantly increases data in this way, and for relevant database, statistical query, updating maintenance can all become
It is more and more difficult, the inquiry of user cannot be timely responded to, working efficiency is reduced, also reduce the experience sense of user.
Relative to relevant database, MongoDB database is more suitable for those and reads in the heavier task of job task,
MongoDB database can make full use of the memory source of machine, if the memory source of machine is abundant, MongoDB number
It can be many fastly according to the search efficiency in library.
Based on this, copy of the MongoDB database as relevant database is established, using relevant database to user
Relational data saved, guarantee the correctness, integrality and consistency of data, using MongoDB database to user
Non-relational data saved, that is, the high stability of relevant database is utilized, also utilizes MongoDB database and holds
The high efficiency of row reading task provides performance guarantee for user query.
Since the business datum of government system is a convergent data acquisition system, user's data of concern can't be constantly
Variation is carved, therefore in the business configuration stage, presets abstract fields information, only extracts necessary business datum and protected
It deposits, improves processing speed, saved space, the demand of user can also be flexibly met.
Business datum only just needs to extract in variation, and generally there are two kinds of scenes for the variation of data: doing in work
It is updated during reason by handling personnel；It is updated in separate functional blocks.And in order to guarantee the consistency of data, in standalone module
Update handled using workflow engine, therefore, the extraction of data copy only needs to carry out during work is handled.
The embodiment of the invention provides a kind of method for promoting data query performance, this method includes by obtaining number of users
According to；And the progress additions and deletions of preset relation type database are changed according to user data and look into operation；The lookup record of user is obtained simultaneously；Root
It is investigated that looking for record, high-frequency data is determined from relevant database；High-frequency data is updated to the MongoDB data pre-established
In library.The present invention guarantees the consistency of data by the way that source data to be stored in relevant database, establish MongoDB database
As the copy of relevant database, non-relational data are saved using MongoDB database, the read and write of data is separated
Come, improves the reading speed of data.
Corresponding to foregoing invention embodiment, high-frequency data is updated to by the description of emphasis of the embodiment of the present invention to be pre-established
Method in MongoDB database, comprising: calls application interface API is updated, utilizes the message queue pre-established
At least one of mechanism is updated and timing updates.
Calling api interface to be updated is by the way that data are updated in MongoDB database using api interface；Periodically
Updating is mainly that leakage detection is filled a vacancy, and is periodically checked the data that need to be updated to MongoDB database, have omission or missing and
When be updated in MongoDB database.
The specific steps being updated using the message queue mechanism pre-established are as shown in Fig. 2, wherein, comprising:
Step S202 obtains multiple message according to high-frequency data, and multiple message are sent to preset message queue
In；
Step S204, using default thread by multiple information updatings in message queue into MongoDB database；
According to high-frequency data, after obtaining multiple message, starting is synchronized to the thread of MongoDB database, sends simultaneously
A piece of news is to message queue；Then thread can run preservation operation.
Step S206 is monitored the renewal process of thread, judges whether thread correctly executes；If correct execute,
Execute step S208；If executing step S210 without correctly executing；
Multiple message are sent to preset monitor, each message includes the thread handled current message
ID, so that monitor judges whether thread correctly executes according to the ID of thread；
Step S208 removes message from message queue；
Step S210 creates new thread by monitor and handles current message.
Monitor only checks that the thread for saving operation is executed either with or without correct: if be currently running, anything is not done, etc.
When message trigger monitor next time (when message is not by response, it will clocked flip monitor)；If having run completion, supervise
This message of device response is listened, this message is removed from message queue, no longer triggering monitor；If thread is by accident
Only, then monitor is responsible for restarting thread, then waits message trigger monitor next time.But if whole system
Delay machine, after recovery is restarted, message queue can correctly send the not message by response, to guarantee that the operation of untreated completion is being supervised
It listens and restores with the help of device.
In data processing, the high-frequency data for needing to synchronize is obtained according to configuration, generates synchronizing data blocks, benefit
With above-mentioned three kinds of modes by its synchronized update into MongoDB database.
When high-frequency data to be updated in MongoDB database, these data may be to be stored in multiple tables of data,
By carrying out logical process to high-frequency data, it will be stored in the form of key-value pair after associated data merging treatment
In MongoDB database, such user can search corresponding number in inquiry, through key-value pair in MongoDB database
According to the keyword for needing to inquire need to be inputted as Baidu search, or counts certain according to desired sort merge
Business handling efficiency of a period etc. facilitates the reading and statistics of data.
Source data is stored in relational database by the embodiment of the present invention based on the considerations of safety, more convenient for data
Newly, non-relationship business datum is saved using MongoDB database kopieren A under mass data, stores data in object using it
It manages in memory, so that the read-write of data becomes very quick characteristic, the read and write of data is separated, number is substantially increased
According to reading speed.The High Availabitity of MongoDB database and aggregated structure possess very high scalability simultaneously, pass through physical machine
Increase and sharing cluster increase, the scalability of MongoDB is up to a very surprising stage, and
In the copy set configuration of MongoDB database, when master library encounters problem, can not continue offer service, copy set will be elected
A new master library continues offer service out, meanwhile, Json (the JavaScript Object of MongoDB database
Notation, abbreviation JS object numbered musical notation) storage format is very with Bson (Binary Serialized Document Format)
