Shown in 1, this method comprises the following steps S102 to step S106:
Step S102, will be in multiple clustered nodes of the pending data according to cutting to HBase database, wherein each cluster
Node is performed both by the line unit value sortord of HBase database after obtaining cutting data.
Specifically, pending data evidence can be amount of access of certain website in a certain period, such as the visit of www.baidu.com
The amount of asking, the amount of access etc. of www.google.comde can also be volumes of searches of certain keyword in a certain period, such as " war of resistance
Review troops live streaming " in September 3 volumes of searches in 2015, " Beijing restricted driving " was in September 3 volumes of searches in 2015.It needs to illustrate
It is that pending data further includes any number for needing to sort according to the volumes of searches not just for above-mentioned website visiting amount and keyword
According to.
Line unit value (rowkey) sortord as possessed by HBase database, when cutting pending data evidence to HBase
When multiple clustered nodes in database, the cutting data in each clustered node are sliced into according to the line unit value sortord
It is ranked up.
Step S104 reads the ranking results of each clustered node, obtains multiple ranking results, wherein each cluster section
After point execution line unit value sortord is ranked up cutting data, a ranking results are obtained.
Specifically, after the cutting data in each clustered node are ranked up according to the sortord of line unit value,
To a ranking results, the ranking results being successively read in each clustered node arrive multiple ranking results.It needs to illustrate
It is that multiple ranking results are stored in multiple clustered nodes in HBase database, for example, when cutting data are certain website
Can be when amount of access, in clustered node a amount of access be 10000 to amount of access be 1000 webpage ranking results, cluster section
Can be in point b amount of access be 999 to amount of access be 100 webpage ranking results, can be for amount of access in clustered node c
99 to amount of access be 0 webpage ranking results.Wherein, after carrying out whole sequence to cutting data, obtained multiple sequences
As a result quantity can be chosen according to the actual needs of user.
Step S106 determines that the collection of multiple ranking results is combined into the ranking results of pending data evidence.It is distributed in multiple clusters
The collection of multiple ranking results in node is combined into the ranking results of pending data evidence.
In the embodiment of the present application, by by pending data according to multiple clustered nodes where cutting to HBase database
In, since HBase database has the line unit value sortord for capableing of auto-sequencing, pending data is according to cutting to multiple collection
, it can be achieved that automatically sequence after group node；Then the ranking results in multiple clustered nodes are read, it will be in each clustered node
The cutting data of completion of having sorted carry out whole sequence according to line unit value sortord again, obtain multiple ranking results, wherein more
The set of a ranking results is the ranking results of pending data evidence, and the application uses the sequence side of HBase database row key assignments
Formula be omitted need in the prior art by the pending data in each clustered node according to merge after can just treat sorting data into
Row sequence link, achieved the purpose that shorten the data sorting time, thus realize do not need in each database wait arrange
Ordinal number solves data sorting low efficiency in the prior art according to merging the technical effect that can be achieved with data sorting
Technical problem improves the performance of data sorting.
Optionally, after each clustered node execution line unit value sortord is ranked up cutting data, one is obtained
Ranking results include the following steps S1041:
Step S1041, clustered node Ai execute line unit value sortord to the cutting data Di of cutting to clustered node Ai
It is ranked up, obtains ranking results Ri, wherein it is the quantity of clustered node in HBase database, cluster that i, which successively takes 1 to n, n,
Node A1 to clustered node An constitute HBase database multiple clustered nodes, cutting data D1 to cutting data Dn constitute to
Sorting data.
Specifically, when cutting pending data is according to the clustered node A1 to clustered node An into HBase database, cutting number
It is stored in each clustered node according to Di with the form of data key values pair is unordered.Then by the data key values of cutting data Di
It is right, it is ranked up according to line unit value sortord, after each clustered node is according to line unit value sortord, obtains one
Ranking results Ri.It is assumed that cutting data Di can be the amount of access of multiple websites in a certain period, if domain name is
The amount of access of the website of www.baidu.com is 10000, then the domain name www.baidu.com of the website and 10000 groups of amount of access
At data key values pair, the data key values are to being expressed as (www.baidu.com 10000)；Similarly, if domain name is
The amount of access of the website of www.google.com is 1000, then the domain name www.google.com of the website and 1000 groups of amount of access
At data key values pair, it is expressed as (www.google.com 1000).
It should be noted that user can be according to the surplus of each clustered node during above-mentioned pending data is according to cutting
Remaining memory space determines the data volume of the cutting data Di being sliced into each clustered node.
The ranking results for determining that the collection of multiple ranking results is combined into pending data evidence include step S1061, clustered node Ai
By the data key values of cutting data Di to storing the ranking results for obtaining pending data evidence to HBase database, wherein cutting
Key-value pair of the data key values of data Di to the total amount of data composition of mark and cutting data Di for cutting data Di.
Specifically, the data key values pair of the cutting data Di in ranking results Ri are read respectively, and according to fixed format
By the data key values of cutting data Di to storing into HBase database.It should be noted that being illustrated in above-mentioned steps
When cutting data Di is website in the amount of access of a certain period, domain name (i.e. cutting of the data key values to that can be the website
The mark of data Di) and the website a certain period amount of access (i.e. the total amount of data of cutting data Di) form.Similarly, if
When cutting data are the volumes of searches of a certain keyword, then the data key values are to can also be keyword (the i.e. mark of cutting data Di
Know) and the keyword a certain period volumes of searches, that is, cutting data Di total amount of data) form.It to sum up describes, cutting data
The data key values of Di form the total amount of data of mark and cutting data Di by cutting data Di.
When cutting data Di is the amount of access of certain website in a certain amount of time, to the cutting data Di in clustered node Ai
When carrying out whole sequence, the data key values of the cutting data Di after whole sequence need to store to HBase orderly
In multiple clustered nodes in database, the ranking results of multiple clustered node compositions are the ranking results of pending data evidence.
Where it is assumed that there is 4 clustered nodes, it can store the cutting data that amount of access is 100000~10000 in clustered node 1, collection
Can store in group node 2 amount of access be 9999~1000 cutting data, clustered node 3 can store amount of access be 999~
100 cutting data, clustered node 4 can store the cutting data that amount of access is 99~0.Clustered node 1 to clustered node 4 is
Clustered node in HBase database, wherein the quantity of clustered node can be chosen according to user's actual needs.
Optionally, in step S1061 clustered node Ai by the data key values of cutting data Di to storing to HBase database
Include the following steps S1 to step S5:
Whether step S1, inquiry HBase database have stored the line unit value of cutting data Di, wherein cutting data Di's
Line unit value is the negative of the total amount of data of cutting data Di.
In the case where having stored the line unit value of cutting data Di in HBase database, cutting data Di is deposited by step S3
Storage to first object arranges, wherein first object be classified as cutting data Di line unit value it is of the row belonging to it is any in column family pair
One column.
Step S5, in HBase database in the case where the line unit value of not stored cutting data Di, according to HBase data
The stored line unit value in library stores cutting data Di key-value pair.
Specifically, in the embodiment of the present application, using line unit value sortord to the cutting data Di in clustered node Ai into
Therefore row sequence when the cutting data Di in clustered node Ai is carried out whole sequence, first obtains the line unit of cutting data Di
Value rowkey, and the line unit value rowkey for whether having stored cutting data Di is inquired in HBase database, wherein line unit value
Rowkey is the negative of the data key values centering total amount of data of cutting data Di.
It is assumed that the data key values of a certain cutting data then should to for (www.baidu.com 10000) in cutting data Di
The line unit value of cutting data is -10000.If line unit value -10000 are inquired in HBase database, by data key values
Domain name " www.baidu.com " in (www.baidu.com 10000) is stored into HBase database, is specifically deposited
The position of storage is any family in column family belonging to line unit value -10000 is of the row.If not inquired in HBase database
Line unit value -10000, then by comparing the size of the line unit value -10000 and the line unit value stored into HBase database
The line unit value -10000 is inserted into the cluster-specific node in HBase database.
It is rowkey:-10000, family:f for having stored the cutting data Di storage form into database
Column:www.baidu.com value:1, wherein family is the mark of HBase physically separate data, and value is
The column name of HBase, when rowkey:-10000 is stored to certain a line, family:f, column:www.baidu.com and
Value:1 stores any family into the affiliated column family of the row of line unit value -10000, and family:f, column:
Www.baidu.com and value:1 are stored in same row.
Further, in step S5, in HBase database in the case where the line unit value of not stored cutting data Di, root
Include the following steps S51 to step S57 according to the stored line unit value storage cutting data Di key-value pair of HBase database:
Step S51 successively compares the big of the line unit value of cutting data Di and the line unit value stored into HBase database
It is small.
Step S53, the target line line unit value of cutting data Di being inserted into HBase database, wherein goal behavior
The first row key assignments next line of the row or the second line unit value lastrow of the row, the first row key assignments and the second line unit value are
Stored line unit value in HBase database, the first row key assignments are line unit value less than cutting data Di, and with cutting data
The smallest line unit value of line unit value difference value of Di, the second line unit value are line unit value greater than cutting data Di, and with cutting data
The smallest line unit value of line unit value difference value of Di.
Step S55 stores cutting data Di to the second target column corresponding with target line, wherein the second target is classified as
Any one column in the affiliated column family of target line.
Step S57, update have stored the line unit value into HBase database.
Wherein, it after updating stored line unit value every time, is deposited in next time according to line unit value stored in HBase database
When storing up not stored cutting data Di key-value pair, corresponding the first row key assignments and the second line unit value can be reaffirmed.One is cut
The key-value pair of divided data Di, if its first row key assignments and the second line unit value all exist, the first row key assignments is less than second
Line unit value.
Specifically, if the line unit value stored in HBase database is -100000, -50000 and -40000, and not stored number
Value be -10000 line unit value, at this time by numerical value be -10000 line unit value respectively with numerical value be -100000, -50000 with -
40000 line unit value is compared.
When cutting data Di is the amount of access of website or is the volumes of searches of certain keyword, user is practical to be preferred to check
Amount of access is former websites, or checks that volumes of searches is former keywords, at this point, with negative in HBase database
Several forms saves line unit value, to arrange line unit value according to sequence from small to large, i.e., arranges according to descending sequence
Column amount of access.
For example, the line unit value for being respectively -100000, -50000 and -40000 with numerical value by the line unit value that numerical value is -10000
It is compared, is respectively less than -10000, and -40000 and -10000 by comparing it is found that -100000, -50000 and -40000
Difference is minimum, therefore -10000 will be inserted into the next line of the row of line unit value -40000, wherein line unit value -40000 namely
For the first row key assignments.In the description in above-mentioned steps S1061 it is found that if in clustered node 1 store amount of access be 100000~
10000 cutting data, line unit value -40000 and -10000 should be stored in clustered node 1, therefore, by numerical value be -
10000 line unit value is inserted into the line unit value next line of the row that numerical value is -40000, and the row for being -10000 by numerical value
Any one column where the line unit value that it is -10000 to numerical value that the cutting data Di of key assignments, which is stored, in the affiliated column family of target line,
In, the line unit value that numerical value is -40000 is the first row key assignments.By above-mentioned sort method, the amount of access to website can be completed
Carry out descending sequence.
In another example if the line unit value stored in HBase database is -5000, -4000 and -1000, and not stored numerical value
For -10000 line unit value, by comparing it is found that -5000, -4000 and -1000 be all larger than -10000, and -10000 with -
5000 difference is minimum, therefore -10000 should be inserted into -5000 lastrow of the row (that is, target line) of line unit value,
In, line unit value -5000 is also the second line unit value.But in the description in above-mentioned steps S1061 it is found that if in clustered node 2
Store amount of access be 9999~1000 cutting data, at this time by numerical value be -10000 line unit value and numerical value be -5000 row
Key assignments is not stored in same clustered node.Therefore, the line unit value that numerical value is -10000 should be stored in clustered node 1, by
It is -10000 in the maximum row key assignments that the line unit value that numerical value is -10000 is in node 1 in all line unit values, therefore by numerical value
Line unit value stores into clustered node 1 last line (that is, target line).
In another example by comparing it is found that storing numerical value in HBase database is -5000, -4000, -1000 and -500
Line unit value, at this time, it may be necessary to be inserted into the line unit value that numerical value is -2000, by will -2000 respectively with -5000, -4000 and -1000 into
