It should be noted that, the content that the generation of key word is specifically paid close attention to according to user is determined, such as, if what user paid close attention to is circle, circle comprises topic, and topic comprises model, at this moment, key word is exactly circle mark, and the some models then going out each topic up-to-date according to circle identifier lookup are shown on the terminal device; If the topic that user pays close attention to, topic comprises model, and at this moment, key word is exactly topic mark, then goes out up-to-date some models according to topic identifier lookup and shows on the terminal device.
The data search method of the embodiment of the present invention, by searching the speed that data can improve inquiry greatly in memory database, still can ensure inquiry velocity when data volume is large.
As shown in Figure 4, the present embodiment also provides a kind of date storage method, is applied to terminal device, and described method comprises:
Step S21: user-generated content is stored to relational database management system RDBMS;
Step S22: the key word corresponding according to described generating content is retrieved in memory database;
Step S23: generate according to result for retrieval or upgrade the doubly linked list corresponding with described key word.
Concrete, use described key word to retrieve in described memory database;
If described key word does not exist, then described key word is used to retrieve in described RDBMS, when result for retrieval is empty, then the doubly linked list of the sky that generation one is corresponding with described key word.
If described key word does not exist, then use described key word to retrieve in described RDBMS, when result for retrieval is not empty, then by all or part of for result for retrieval data-pushing in the doubly linked list corresponding with described key word.
It should be noted that, if do not generate empty doubly linked list, then, when needs obtain data, just look for not corresponding chained list, now just need RDBMS to look into number according to storehouse, one query will have been done more like this, reduced overall system performance.Therefore overall search performance can effectively be improved by generating empty doubly linked list.
Technique scheme uses the storage organization of doubly linked list as each topic node of Redis, the persistence of its user-generated content data, still uses RDBMS to store.In chained list, limit storage element number, according to business need, the data exceeding displaying scope are directly deleted simultaneously.In addition, for the node of the countless certificate of part, the mode of newly-built empty chain table is used to be optimized.
The performance bottleneck of existing RDBMS storage is effectively overcome by technique scheme, utilize the high-speed read-write characteristic of this internal memory of Redis type database to carry out auxiliary RDBMS retrieval user and pay close attention to circle topic content-data, significantly improve inquiry velocity, and alleviate the pressure of RDBMS.To upgrade in time Redis database according to newly-increased content simultaneously, ensure data query speed and validity further.
Embodiment two
In the present invention, effectively can be improved the speed of data retrieval by Redis database.Redis database is that a use ANSI C of increasing income is write, network enabled, can also can log type, the Key-Value database of persistence based on internal memory, and provide multilingual API.
Redis is a key-value storage system.Similar with Memcached, it supports that the value type stored is relatively more, comprises string (character string), list (chained list), set (set), zset (sortedset--ordered set) and hash (Hash type).These data types are all supported push/pop, add/remove and are got common factor union and difference set and abundanter operation, and these operations are all atomicities.On this basis, Redis supports the sequence of various different modes.The same with memcached, in order to guaranteed efficiency, data are all be buffered in internal memory.What distinguish is that redis periodically the data write disk upgraded or the log file that retouching operation write is added, and can achieve master-slave (principal and subordinate) synchronously on this basis.
Meanwhile, Redis is a high performance key-value database.Redis largely compensate for the deficiency that this kind of key/value of memcached stores, and can play good supplementary function in part occasion to relational database.It provide Java, the clients such as C/C++, C#, PHP, JavaScript, Perl, Object-C, Python, Ruby, Erlang, use easily.
In addition, Redis supports master-slave synchronisation.Data can synchronous from server from master server to any amount, can be other master servers from server of association from server.This makes Redis can perform individual layer tree copying.Deposit consciously or unconsciously can carry out write operation to data.Owing to fully achieving publish/subscribe mechanism, make from database anywhere synchronization tree time, a channel can be subscribed to and receive the complete news release record of master server.Synchronously to the extensibility of read operation and data redundancy helpful.
Further illustrate technical scheme of the present invention below.
In the present embodiment, the storage of user-generated content can be carried out according to following steps:
1) user-generated content is stored to RDBMS database;
2) next call the Key maker write and generate key word, then use this key word to retrieve in Redis.
If this key word does not exist, then according to the rule search RDBMS of operation flow definition.If the result of retrieval is not empty, then by after the results list serializing of restriction quantity, rpush is used to be pushed in the doubly linked list of corresponding Key in Redis.If result is empty, then calls lpush and push an any character, then call lpop and release, so just obtain an empty doubly linked list.Utilize the doubly linked list of this sky, in again inquiring about this node data user, without the need to from RDBMS data base querying, and only need the Redis back end in audit memory.
If this key word exists, this serializing instrument data call of new node element write, sequence turns to the form of character string.
3) lpush is used to be pushed to corresponding key word node the result of serializing.
Based on the memory database that above-mentioned storage means is formed, user-generated content can read data according to following steps:
1) contents list that retrieval user is paid close attention in RDBMS.
2) travel through the major key mark in contents list, call Key maker by major key mark and generate key word, from Redis, obtain node data with the key word generated.
If this key word does not exist, then according to the rule search RDBMS of operation flow definition, and rpush is used to be pushed in the doubly linked list of corresponding Key in Redis the result limiting quantity.Be that VO object returns to user by the data-mapping of retrieval simultaneously.
If this key word exists, but the element number comprised is for empty, and this situation is judged to be that this topic is without content-data.Return to the contents list of user's sky.
3) if this key word exists, content is not empty, then by after data antitone sequence, transfer VO object to and return to user.
Technical scheme of the present invention is further illustrated below in conjunction with concrete scene.
Be a light photography applications sharing picture as shown in Figure 5, wherein comprise a circle dynamic module.3 up-to-date post information of the circle that circle dynamically needs the user obtaining current login to pay close attention to.What Fig. 5 showed is a visual field circle dynamic page, and in this page, the new page added is placed in the 3rd TAB page of homepage; Circle dynamic page display user add the dynamic of circle, data put in order can be according to circle last operation time inverted order arrangement.Comprise information in circle dynamic page and can have circle title, add number, topic number, circle last operation time and circle recent renewal 3 contents etc.Wherein can comprise new topic (topic front cover and topic name), new topic works (topic works and works belonging to topic name) inside content.Corresponding circle dynamic page is just entered when user clicks circle module.User can also select acquiescence to add visual field circle.
What the present invention can adopt is following flow process:
1, the unique identification UserID of current login user is obtained.
2, the circle list of this user concern is obtained by this UserID.
3, generate key according to circle ID to go directly to search data in Redis, because Redis is memory database, therefore acquisition speed is inquired about faster than RDBMS far away.If returning results not is sky, after unserializing data, jump to 5; Otherwise jump to 4.
4. because key word is miss, need to inquire about in RDBMS, then the data of searching write Redis is jumped to 5 again.
Concrete, in step 4, first travel through each circle of above-mentioned circle list, according to the topic list that circle ID goes inquiry circle to comprise.Then travel through above-mentioned topic list, remove data query according to topic ID.
5. return data is held to APP.
Such as, the list split of 3 models of the topic that each circle can be comprised becomes a list, i.e. the up-to-date model list that comprises of circle, and according to time inverted order arrangement.And find ID and the topic name of topic corresponding to model, for display.APP can show the content such as topic name, model surface plot URL, topic ID of the up-to-date model of each circle.Certainly, in other embodiments, also can the up-to-date model of set and display 4 or other number, be not specifically limited at this.
In such scheme, preserve a Redis object for each circle, when each newly-increased model, the data that simultaneously can upgrade Redis to ensure wherein are up-to-date.If when having inquired the circle preserved in Redis, namely hit, now just do not need RDBMS data base querying just directly the data of inquiry can be returned to APP end, this avoid complicated database query operations, inquiry velocity obtains very large lifting again.If miss when Redis searches, then search in RDBMS database, and the data found are saved to Redis, like this in time again inquiring about this circle, owing to being saved in Redis by these data, can the time of searching be saved equally.Therefore, technique scheme can utilize Redis significantly to promote inquiry velocity.
