Specific embodiment
For the user of the network platform, each user property of user can be defined as one " dimension " (dimension), often
The user data of a user can be made of the data of multiple " dimensions ", and each " dimension " can correspond to a kind of user property of user.
Herein by by network implementations to the platform of the scheduling of the vehicles (such as vehicle) for the technical program is introduced.It is handing over
For each user of logical tool dispatching platform, user property can include: gender, the age, city, consumption type, user tag,
The expense etc. that the frequency of maneuver traffic tool, maneuver traffic tool generate, each user property corresponds to an attribute value, e.g.,
Age: 28, city: Beijing.
In the network platform, it usually needs stamp a user tag to each user, user is assigned to different classes
Not.Based on user tag, can in order to be screened to certain types of user, and in order to realize more efficient data analysis with
And query function, it generally requires to construct index (index) to user data, to realize the analysis and inquiry of second grade.It is sent out in business
During exhibition, user data can constantly change, and need to update database in time thus.In the related art, it updates
The value of some dimension (user property) generally requires to carry out re-creating index to other a large amount of dimensions, increases index database
It updates time-consuming.It is proposed to this end that following technical solution of the invention, to improve data updating efficiency.
Fig. 1 is a kind of flow chart of the method for update index database shown according to an exemplary embodiment, and this method is held
Row main body can for all kinds of electronic equipments (such as the network equipment, server, server cluster, user equipment, terminal device or other
The calculating equipment of type).As shown in Figure 1, in one embodiment, this method can be by 101~step 103 of following step come real
It is existing, in which:
In a step 101, the user list for by target user's attribute assignment being Target Attribute values is received, wherein institute
Stating user list may include at least one user identifier.
In one embodiment, the index database can be ElasticSearch (referred to as ES in text) index database.Wherein,
ES is an expansible open source search engine.ES can construct rope using inverted index (Inverted index) mode
Draw.Wherein, ES index database may include multiple ES nodes, and each ES node can be responsible for the data of one index fragment of storage.
Although in the network platform there are many kinds of the user properties of each user, actually data variation frequency is relatively high
User property and few.In the present embodiment, target user's attribute can refer to the relatively high user property of change frequency,
Determine target user's attribute mode include it is very much, be exemplified below several: 1., by operation personnel rule of thumb judging which is used
The change frequency of family attribute is relatively high, is chosen to be target user's attribute.2., count using big data each user and belong to
Property variation frequency, and carry out ranking from high to low according to frequency, the user property of preceding n (n >=1) position may finally be taken, as
The relatively high target user's attribute of change frequency.In one embodiment, target user's attribute includes but is not limited to: Yong Hubiao
Label (as: the labels such as consumption type belonging to black list user, white list user or user).
In one embodiment, above-mentioned user list can be uploaded to point by user (i.e. the operational staff of data update action)
Cloth file system (Hadoop Distributed File System, HDFS), and be inserted into mysql by user one with
The corresponding Target Attribute values of target user's attribute.Wherein, user list can also be other than being uploaded by user according to specific rule
Then generate.
In a step 102, it creates at least one more new thread and is put into thread pool.It, can be with to improve index upgrade speed
Create multiple threads that can be executed parallel.Per thread from HDFS for successively reading user's column according to certain sequence
User identifier in table, and data update action is carried out one by one to each user identifier.
In step 103, using the more new thread, by the corresponding relationship of the user identifier and the Target Attribute values
The first memory block in the index database is written and index is updated to the data in first memory block.
In an optional embodiment, the step 103 can specifically include step 131 and step 132, in which:
Step 131: setting lattice being met to each user identifier generation in the user list using the more new thread
The message of formula, wherein the message includes the user identifier and the Target Attribute values.
For example, identifying for each of user list user (driver or passenger), more new thread can construct as follows
The message of format: { " passenger_id ": " 12345 ", " tags ": [" tag_id "] }.Wherein, " 12345 " are user list
In some user identifier, " tag_id " refers to Target Attribute values.
Step 132: Xiang Suoshu index database sends the message, with first memory block be written the user identifier and
The corresponding relationship of the Target Attribute values.
As it can be seen that when needing to be updated target user's attribute in user data, it can be by for target to be used
Family attribute assignment is the user list of Target Attribute values, and creates more new thread, final to be updated institute using more new thread
It states the first memory block in index database and makees index upgrade.It is not needed in the above process in the dimension for not needing to update to other
User data be indexed update, greatly improve data update efficiency.
101~step 103 of above-mentioned steps can daily in be performed a number of times.When user needs based on target user's attribute
(such as user tag) when inquiring, can inquire newest data from the first memory block in above-mentioned index database.
In an optional embodiment, after step 101, the method can also include step 11 and step 12,
In:
Step 11: obtaining current version ID corresponding with the Target Attribute values.
It changed may be asked to solve the corresponding user group's (i.e. user id list) of the same Target Attribute values
Topic, such as: some Target Attribute values is " blacklist ", which may often change.To solve this problem, we give
" blacklist " this Target Attribute values increase corresponding revision ID.Also, the revision ID can be continuously updated.
Step 12: according to current version ID, determining revision ID to be updated corresponding with the Target Attribute values.
For any one Target Attribute values x, when the Target Attribute values are increased newly (without older version before i.e.)
When, when indicating the Target Attribute values, it can be denoted as " x_1 ", wherein " 1 " in " x_1 " can represent the target category
The revision ID of property value x.(such as: uploading Target Attribute values again when the user group that Target Attribute values x is covered changes
For the user list of x), then revision ID to be updated corresponding with the Target Attribute values is " 2 ", and so on.That is, to
Update revision ID=current version ID+1.
Correspondingly, in the present embodiment, step 103 can be with specifically: using the more new thread, by the user identifier
Corresponding relationship between the Target Attribute values comprising the revision ID to be updated is written first memory block, and to described the
Data in one memory block update index.
After carrying out version management using revision ID, more new thread can construct the message of following format: "
passenger_id":"12345","tags":["tag_id_version"]}.Wherein, " tag_id_version " is contained
Revision ID and Target Attribute values.
By setting a revision ID for Target Attribute values, and some target user's attribute in the first memory block is carried out
After data update, it is the user of " x " if necessary to searched targets attribute value, then can takes out the objective attribute target attribute from mysql
The latest edition ID of value, and inquired using latest edition ID.For example, latest edition ID is 10, then what is inquired is target
Attribute value is all users of " x_10 ".
In one embodiment, in order to which whether verify data renewal process succeeds, after above-mentioned steps 103, the method
It can also include step 21~step 23, in which:
Step 21: generate query statement, the query statement for inquire in first memory block with comprising it is described to
Update the corresponding number of users of Target Attribute values of revision ID.
For example, the query statement generated can be DSL (domain specific languages, field language-specific)
Sentence.
Step 22: executing the query statement, the number of users is obtained with inquiry.
Step 23: if the number of users is equal to the number of users that the user list includes, determining that data are updated successfully；It is no
Then, determine that data update failure.
The first memory block can be inquired every certain time length, obtain the corresponding value of target user's attribute being inserted into
Are as follows: the number of users of " tag_id_version ".Wherein it is possible to obtain the number and/or continuous return value that continuous-query fails
Equal number.If the number of users for including in the number of users and user list that return is equal, finished it may be considered that establishing index
(i.e. data are updated successfully), setting up vertical Index Status is " success ".If the number of continuous-query failure reaches certain value, or continuous
The equal number of inquiry return value reach certain value and the number of users that returns is not equal to the number of users for including in user list,
Then think to establish index failure (i.e. data update failure).After determining that data update failure, user can be sent notification to, with
Data are updated again.
Fig. 2 is the flow chart according to another method for updating index database shown in an exemplary embodiment.This method
Executing subject can for all kinds of electronic equipments (such as the network equipment, server, server cluster, user equipment, terminal device or its
The calculating equipment of his type).
As shown in Fig. 2, this method can be realized by 201~step 202 of following step.Realizing step 201 and step
Before rapid 202, the index database further includes one second memory block, and the number of the user property of second memory block storage is greater than institute
State the number of the user property of the first memory block storage.In one embodiment, the second memory block can be used to store whole users
The data of attribute, and the first memory block is then used to store the higher one or more target user's attributes of renewal frequency.Wherein, institute
Stating the user property stored in the second memory block includes but is not limited to one or more of: user's gender, age of user, user
The area at place, user tag, the frequency for participating in vehicles scheduling events, the number for participating in vehicles scheduling events.
In step 201, it when the execution time of timed task arrives, obtains each user and belongs to about the target user
The newest attribute value of property.
Wherein, the fixed time interval of the timed task can be one day, then executing the time can be for a time point (such as
23:00:00) or some period.
Because certain user may be by more in the assignment (i.e. attribute value) of target user's attribute (such as: user tag)
Newly, still, it often only being updated in the first memory block, the second memory block may still remain original data, this
When, newest attribute value of all users on this dimension of user tag can be collected into from HDFS.Receiving correlation
After data, the mechanism of inverted index similar can be established, a hive table is written into the data being collected into, wherein a column are to use
Family id, another column are user tags, then, the hive table and the user data of other dimensions are merged, finally led together
Enter in the second memory block into index database.Wherein, " newest attribute value " can be defined as: in the execution time of timed task
When arrival, attribute value that target user's attribute is endowed in the execution time recent renewal time point.
In step 202, the newest attribute value using each user got about target user's attribute, to institute
It states the user data in the second memory block and is indexed update.
After step 202, DSL sentence can be constructed, every currently being indexed ES of a Duan Shichang (such as 5 minutes) inquiry
Number of files, when the equal times for the result that inquiry returns reach certain value, it is believed that write-in terminates, and according to inquiry user
The ratio of number and user's number of actual needs write-in, judges whether that data are written successfully, and report user.
As it can be seen that by being updated the data of the higher target user's attribute of renewal frequency within a short period of time to the first storage
Area, and the newest attribute by the timed task of a longer fixed time interval by each user about target user's attribute
Value is updated to the second memory block, so that the dimension often changed in user characteristics and independent point of dimension infrequently changed
It Gou Jian not index and store, both be able to satisfy the requirement of data updating efficiency, and the dimension for often changing in user characteristics,
As long as renewal process also carries out rebuilding index to the field of a small amount of several variations again.Can will own by timed task
Effective user tag is updated into the second memory block, also, the higher user tag of renewal frequency is carried out real-time update and is arrived
First memory block.Most user tag is inquired, it is only necessary to be inquired from the second memory block, guarantee data
It may also be ensured that efficiency data query is unaffected while timely updating.
