It is related, for example, user-generated content can be the model content etc. that user is sent in circle.Meanwhile it is two-way can in chained list
To limit the number of storage element, it will exceed according to business need and show that the data of range are directly deleted.In addition, being directed to part nothing
The node of data, the mode that newly-built empty chain table can be used optimize.
As shown in figure 3, being applied to terminal device the present embodiment provides a kind of data search method, which comprises
Step S11: the contents list of user's concern is obtained according to the mark of the user of acquisition；
Step S12: keyword is generated according to the mark of content in the contents list；
Step S13: data are searched in memory database by the keyword；
Specifically, searching data in memory database by the keyword；When there are institutes in the memory database
When to state keyword and lookup result be not sky, the data found are subjected to inverted sequence column processing.
When the keyword is not present in the internal storage data, according to content identification in relational database management system
Data are searched in RDBMS, and the memory database is written into the data of lookup.
When, there are the keyword and when lookup result is empty, returning to empty contents list in the memory database.
Wherein, the memory database being written in the data of lookup can operate in the following way: according to presetting
Restriction quantity the data-pushing found in RDBMS is corresponded to the Two-way Chain of keyword into the memory database
In table.
In the present embodiment, the corresponding doubly linked list of each keyword in memory database.Memory database uses
REDIS database；The number of doubly linked list storage element is less than or equal to preset maximum number.
It should be noted that the content paid close attention to specific reference to user of the generation of keyword is determined, for example, if user pays close attention to
Be circle, circle includes topic, and topic includes model, and at this moment, keyword is exactly circle mark, is then looked into according to circle mark
The newest several models of each topic are found out to show on the terminal device；If the topic of user's concern, topic includes model, this
When, keyword is exactly topic mark, then goes out newest several models according to topic identifier lookup and shows on the terminal device.
The data search method of the embodiment of the present invention can greatly improve inquiry by searching data in memory database
Speed, can still guarantee inquiry velocity when data volume is big.
As shown in figure 4, the present embodiment also provides a kind of date storage method, it is applied to terminal device, which comprises
Step S21: user-generated content is stored to relational database management system RDBMS；
Step S22: it is retrieved in memory database according to the corresponding keyword of the generation content；
Step S23: doubly linked list corresponding with the keyword is generated or updated according to search result.
Specifically, being retrieved in the memory database using the keyword；
If the keyword is not present, retrieved in the RDBMS using the keyword, when search result is sky
When, then generate the doubly linked list of a sky corresponding with the keyword.
If the keyword is not present, retrieved in the RDBMS using the keyword, when search result is not
When empty, then by all or part of data-pushing of search result into doubly linked list corresponding with the keyword.
It should be noted that just being looked for not corresponding if not generating empty doubly linked list when needing to obtain data
Chained list just needs RDBMS to look into number according to library at this time, can thus do one query more, reduce overall system performance.Therefore
Whole search performance can be effectively improved by the doubly linked list for generating empty.
Above-mentioned technical proposal uses the doubly linked list of Redis as the storage organization of each topic node, and user generates
The persistence of content-data, is still stored using RDBMS.Storage element number is limited in chained list simultaneously, according to business
It is required that the data beyond displaying range are directly deleted.In addition, being directed to the node of part no data, the side of newly-built empty chain table is used
Formula optimizes.
The performance bottleneck for effectively overcoming existing RDBMS storage through the above technical solution, utilizes this memory type of Redis
The high-speed read-write characteristic of database pays close attention to circle topic content-data to assist RDBMS to retrieve user, greatly improves inquiry speed
Degree, and alleviate the pressure of RDBMS.It is timely updated Redis database according to newly-increased content simultaneously, is further ensured that data
Inquiry velocity and validity.
Embodiment two
In the present invention, the speed of data retrieval can effectively improve by Redis database.Redis database is one
Being write using ANSI C language of open source, support network, it is memory-based also can the log type of persistence, Key-Value data
Library, and the API of multilingual is provided.
Redis is a key-value storage system.Similar with Memcached, it supports the value type phase of storage
To more, including string (character string), list (chained list), set (set), zset (sorted set-- ordered set) and
Hash (hash type).These data types all support push/pop, add/remove and take intersection union and difference set and Geng Feng
Rich operation, and these operations are all atomicities.On this basis, Redis supports the sequence of various different modes.With
Memcached is the same, and for guaranteed efficiency, data are all to cache in memory.Difference is that redis can be periodically update
Data write-in disk or modification is operated the additional record file of write-in, and realize master- on this basis
Slave (principal and subordinate) is synchronous.
Meanwhile Redis is a high performance key-value database.Redis largely compensates for memcached
The deficiency of this kind of key/value storage, in part, occasion can play good supplementary function to relational database.It is provided
The clients such as Java, C/C++, C#, PHP, JavaScript, Perl, Object-C, Python, Ruby, Erlang, using very
It is convenient.
In addition, Redis supports master-slave synchronisation.Data can be synchronized from server from primary server to any number of,
It can be from server and be associated with other primary servers from server.This makes Redis that single layer tree copying can be performed.Deposit can be with
Consciously or unconsciously to data carry out write operation.Due to fully achieving publish/subscribe mechanism, so that anywhere from database
When synchronization tree, a channel can be subscribed to and receive the complete news release record of primary server.Synchronize expanding to read operation
Malleability and data redundancy are helpful.
Technical solution of the present invention is further illustrated below.
The storage of user-generated content can follow the steps below in the present embodiment:
1) user-generated content is stored to RDBMS database；
2) it next calls the Key generator write to generate keyword, is then examined in Redis using the keyword
Rope.
If the keyword is not present, the rule search RDBMS that is defined according to operation flow.If the result of retrieval is not
The doubly linked list that Key is corresponded in Redis is pushed to using rpush then by after the serializing of limited number of the results list for sky
In.If result is sky, lpush is called to push an any character, recalls lpop release, thus obtain a sky
Doubly linked list.Using this empty doubly linked list, will be not necessarily to when user inquires the node data again from RDBMS
Data base querying, and only need the Redis back end in audit memory.
If the keyword exists, this serializing tool for writing the data call of new node element, sequence turns to word
Accord with the form of string.
3) result of serializing is pushed to corresponding keyword node using lpush.
Based on the memory database that above-mentioned storage method is formed, user-generated content can read number according to the following steps
According to:
1) contents list of user's concern is retrieved in RDBMS.
2) the major key mark in traversal content list, is identified by major key and Key generator is called to generate keyword, with generation
Keyword node data is obtained from Redis.
If the keyword is not present, the rule search RDBMS defined according to operation flow, and by limited number of knot
Fruit is pushed in the doubly linked list for corresponding to Key in Redis using rpush.The data of retrieval VO object is mapped as simultaneously to return
To user.
If the keyword exists, but the element number for including is sky, and such case is determined as the topic without content number
According to.Return to the contents list of user's sky.
If 3) keyword exists, content is not sky, then by after data antitone sequence, switchs to VO object and return to user.
Technical solution of the present invention is further illustrated below with reference to specific scene.
It is a light photography applications for sharing picture as shown in Figure 5, wherein including a circle dynamic module.Circle dynamic
Need to obtain newest 3 post informations of the user currently logged in circle of interest.Fig. 5 shows a visual field circle
Dynamic page, in the page, the newly added page is placed in TAB pages of third of homepage；Circle dynamic page shows that user is added
The dynamic of circle, the time inverted order arrangement that can be according to circle last operation that puts in order of data.It is wrapped in circle dynamic page
In 3 for can having circle title, addition number, topic number, circle last operation time and circle recent renewal containing information
Hold etc..It may include wherein new topic (topic cover and topic name), new topic works (topic works and works inside content
Affiliated topic name).Corresponding circle dynamic page is entered when circle module when the user clicks.User is also an option that default adds
Enter visual field circle.
The present invention can be using following below scheme:
1, the unique identification UserID of currently logged on user is obtained.
2, the circle list of user concern is obtained by the UserID.
3, key is generated according to circle ID to go directly to search data in Redis, since Redis is memory database, obtain
Speed is taken to be significantly faster than RDBMS inquiry.If returning the result not for sky after unserializing data, 5 are jumped to；Otherwise it jumps to
4。
4. needing to inquire into RDBMS due to keyword miss, then the data write-in Redis of lookup is jumped again
To 5.
Specifically, in step 4, traversing each circle of above-mentioned circle list first, inquiry circle is gone according to circle ID
The topic list for being included.Then above-mentioned topic list is traversed, inquiry data are gone according to topic ID.
5. returning data to the end APP.
For example, the list split of 3 models of the topic that can included by each circle becomes a list, i.e. circle
The newest model list for being included, and arranged according to time inverted order.And find the ID and topic of the corresponding topic of model
Title, for showing.APP can be shown in the topic name of the newest model of each circle, model surface plot URL, topic ID etc.
Hold.Certainly, in other embodiments, the newest model that can also set display 4 or other numbers, does not do specific limit herein
It is fixed.
In the above scheme, a Redis object is saved for each circle, when each newly-increased model, simultaneously
Redis be will be updated to guarantee that data therein are newest.If inquired the circle being saved in Redis, that is, hit, this
When there is no need to RDBMS data base queryings again the data of inquiry directly to be returned to the end APP, this avoid complicated
Database query operations, inquiry velocity obtain very big promotion.If the miss when Redis is searched, in RDBMS data
It is searched in library, and the data found is saved to Redis, in this way when inquiring the circle again, due to should
Data are saved into Redis, can equally be saved and be searched the time.Therefore, above-mentioned technical proposal can be substantially improved using Redis and be looked into
Ask speed.
