Embodiment
For making object of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, scheme of the present invention is described in further detail.
Core concept of the present invention is: to user, need to create the memory size that the data content of index takies at every turn and add up, divide targetedly user to carry out corresponding capacity management, can be accurately and obtain easily certain user the memory capacity of use carry out limited capacity, thereby illegal uncontrolled malicious user that creates the data stream of index limited.
The embodiment of the present invention provides a kind of search engine space hold statistical method, and as shown in Figure 1, the method comprises its schematic flow sheet:
Step 11, for each user preserves corresponding user capacity, take list in advance, described user capacity takies list and comprises user profile and corresponding capacity quota information; Wherein, capacity quota information comprises that this user allows use capacity and taken capacity;
This step is used for carrying out information retrieval, thereby carries out user validation checking, only finds corresponding user capacity and takies list, just can carry out follow-up statistic procedure.
Particularly, for different production environments, there are two kinds of ways of accurate statistics and fuzzy statistics:
Wherein, precise statistical method is applicable to the index creation production scene that pressure is less heartily: the content that need to create index to this time is accurately added up, obtain the quantity of Chinese character and English character, according to Chinese character and each self-corresponding byte length of English character, change and add up, obtain the storage space occupancy that this time need to create the content of index.For example, the content that need to create index of carrying in index creation request is " 2013/06/11 13:12:11 user Zhang San login ", one of them journal entries that this daily record that is some program produces is flowed, according to English, account for a byte, Chinese accounts for two bytes, space also accounts for a byte, and it is 35 bytes that cumulative this journal entries obtains the storage space occupancy that this time need to create the content of index.
Statistics Method is applicable to the concurrent establishment index of this height of cloud daily record, the scene that performance pressure is very large.In the situation that performance pressure is very large, is not very applicable to character one by one and removes to analyze the content of text that needs create index.Therefore, the content that need to create index to this time is carried out fuzzy statistics, presets the Chinese and English weight that this time need to create the content of index, according to described Chinese and English weight, obtain Chinese and English byte length and, obtain the storage space occupancy that this time need to create the content of index.For example, user a needs fuzzy statistics, generally, the Chinese weight of a is 30%, so, and the data stream contents of user a, can add up according to 30% Chinese and 70% English, obtain the storage space occupancy that this request need to create the data stream of index.Wherein, Chinese and English weight can dynamically be adjusted in real time according to concrete application and actual conditions.
Also have a kind of situation, the content of some daily record, is all generally to take English as main, so can directly obtain the string length of the content of text that need to create index, according to English, calculates storage occupancy.
Wherein, the capacity that takies that upgrades this user can be divided into real-time update and regularly upgrade two kinds.
User after upgrading has taken capacity and will deposit database module, i.e. data persistence in.But general as an internet, applications that service is externally provided, user and the number of applications of access are huge, and persistence can easily can cause database bottleneck in real time.So, need in the database module of search engine space hold statistical system, safeguard that a user capacity takies list, for user capacity takies list, cumulative threshold values and time threshold values are set in advance, when creating the storage space occupancy of the content of index, reach cumulative threshold values or time threshold values, upgrade the capacity that takies that described user capacity takies list.For instance, the request amount that certain user's single is come, cumulative this user capacity that is maintained into takies list the inside, when reaching the cumulative threshold values 5,000,000 of system setting, just starts persistence.For example request amount is 1,000,000 for the first time, and request amount is 2,000,000 for the second time, and request amount is 3,000,000 for the third time, and each request amount is first temporarily stored in the internal memory of proxy module, when cumulative value is 6,000,000, has surpassed cumulative threshold values 5,000,000, just starts persistence.And, a time threshold values also should be set, for example every half an hour, go user capacity to take the whole persistences of data of list the inside.By the reasonable setting to cumulative threshold values and time threshold values, just can accomplish data persistence relatively accurate and quasi real time, even if proxy module occurs wrongly having worked as machine, the data of loss also shared ratio are also minimum.Above-mentioned mentioned database module, proxy module etc. can be introduced in detail in follow-up system.
Preferably, after receiving user's index creation request, the method further comprises: according to described index creation request, create index; The method of described establishment index comprises participle, then preserves the content that need to create index.Wherein, the process that creates index according to index creation request still retains prior art, does not repeat them here.
Preferably, in step 11, for each user preserves corresponding user capacity, take list, wherein, it is the registration according to user that user capacity takies list, for user configuration forms.
Inventive concept based on same, the present invention also proposes a kind of search engine space hold statistical system, and referring to Fig. 2, Fig. 2 is the structural representation that is applied to the search engine space hold statistical system of said method in the specific embodiment of the invention.In figure, each module is comprised of a plurality of servers, and each module is a server cluster.This search engine space hold statistical system comprises:
Database module 201, for taking list for each user preserves corresponding user capacity in advance, described user capacity takies list and comprises user profile and corresponding capacity quota information; Wherein, capacity quota information comprises that this user allows use capacity and taken capacity;
Proxy module 202, for receiving user's index creation request, described index creation request comprises user profile and need to create the content of index;
According to described user profile, find corresponding user capacity and take list;
The content that need to create index to this time is carried out analytic statistics, obtains the storage space occupancy of the content that this time need to create index;
The storage space occupancy that need to create the content of index according to this time adds up to the described capacity that taken, and upgrades this user's the capacity that takies.
Preferably, this system further comprises:
Search engine module 203, for creating index according to described index creation request; The method of described establishment index comprises participle, then preserves the content that need to create index.
Preferably, this system further comprises:
Administration module 204, for according to user's registration, takies list for user configures corresponding user capacity, and preserves described user capacity and take list to database module 201.
Further, described proxy module 202 further comprises:
Receive submodule 2201, for receiving user's index creation request, described index creation request comprises user profile and need to create the content of index;
Particularly, this reception submodule is provided with service interface, and for example HTTP interface, can receive user's index creation request from service interface.
Search submodule 2202, for finding corresponding user capacity according to described user profile, take list;
Statistics submodule 2203, carries out analytic statistics for need to create the content of index to this time, obtains the storage space occupancy of the content that this time need to create index;
Upgrade sub module stored 2204, for need to create the storage space occupancy of the content of index according to this time, the described capacity that taken is added up, upgrade this user's the capacity that takies.

2) user sends index creation request and arrives proxy module:
After becoming validated user, can use the service of search engine.For example user A, has one now in the program of operation, needs output journal.Because search engine can provide some convenient powerful functions, such as navigating to fast certain a line daily record according to key word, log content being provided to the functions such as analysis, user A calls the interface that proxy module provides, when being output, just the data stream of this journal entries is sent to proxy module in a journal entries is carried at index creation request.For example this rule object content is: " 2013/06/11 13:12:11 user Zhang San login ".
Proxy module receives after the data stream of this journal entries, from solicited message the inside, obtaining out this data stream is to come from user A, then from corresponding user capacity, takies user profile list and capacity quota information the inside and matches the limit of user A and use amount.Meanwhile, for production environment, adopt corresponding statistical method, the string length of the data stream of this journal entries of analytic statistics.
As 1) said, user is in registration, be assigned with quota, proxy module is when starting, the capacity quota information (allow use capacity and taken capacity) that can load (reading) user profile and correspondence from database module, to internal memory, forms the data structure of a key-value pair.After startup, at set intervals, can reload once, be written into newly-increased information.And proxy module is counting the string length of the data stream of this journal entries, obtain after the storage space occupancy of this content that need to create index, renewal can add up to the capacity that takies in database module.This shows, be two-way interactive between proxy module and database module.
3) index creation request arrives search engine module through proxy module, and search engine module creates index according to described index creation request.
It should be noted that, in the embodiment of the present invention, user's index creation request only need to send once, through proxy module, arrive search engine module, like this, user will enter search engine module and index, and the flow that must need to create the data stream of index to each through proxy module is added up, and the phenomenon of statistics can not occur to omit.
