Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.By these exemplifying embodiments of enough detailed description, those skilled in the art are made to put into practice the present invention.Without departing from the spirit and scope in the present invention, can to implement to make logic, realize and other change.
In the present invention, need to dispose distributed type assemblies environment, such as, this distributed type assemblies environment has 3 nodes, and the configuration of each node is 96G internal memory, and 12 core, hard disk is 12*1T.
Fig. 1 is the configuration diagram that the present invention is based on the inquiry of HBase secondary index table.HBase source table is set up in HBase client, User Table as illustrated in the drawing, also the corresponding secondary index table setting up correspondence, Index Table as illustrated in the drawing, wherein in secondary index table, Rowkey is formed according to corresponding Rowkey in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, and property value corresponding in secondary index table is that in the table of HBase source, Rowkey and Column Properties value are formed.
Fig. 2 is the schematic flow sheet of the querying method of HBase secondary index table of the present invention, as shown in Figure 2, specifically can comprise:
Step 21, judges whether HBase source table has corresponding secondary index table, if do not had, enters step 22; If had, enter step 23.
In this step, HBase client judges whether HBase source table has corresponding secondary index table, the function of this secondary index table is whole records of property value in the row that can realize fast query HBase table, according to the highly-parallel performance of Distributed Architecture there is good time efficiency to during secondary index table handling, set up corresponding secondary index table according to HBase source table, the operation checking the property value meeting a certain row can be made to realize fast and the performance of inquiry can be improved.
Step 22, according to Rowkey corresponding in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, create and show corresponding secondary index table with HBase source, and the data of synchronous HBase source table are in the secondary index table of correspondence, enter step 23.
In this step, according to Rowkey corresponding in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, utilize Rowkey and the property value of the secondary index table of revertrow function and Map function creation HBase source table correspondence, and the data of synchronous HBase source table are in the Rowkey and property value of the secondary index table of correspondence.
Particularly, utilize revertrow function, according to Rowkey corresponding in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, the Rowkey of secondary index table is set.
Utilize Map function, according to ImmutableBytesWritable key parameter and Result value parameter, extract Rowkey and the value value in the table of HBase source, travel through each KeyValue and obtain Rowkey in corresponding secondary index table, and the property value of secondary index table is set according to the Rowkey of HBase source table and Column Properties value.
Revertrow function is called in Map function, the rreturn value Rowkey of revertrow function is preserved, and according to the newly-built Put object of this rreturn value Rowkey, the Put object newly-built for this adds corresponding property value, and this property value is the Rowkey of HBase source table and the combination of Column Properties value that extract.Use ImmutableBytesWritable object encapsulation, use Context.write event memory.
In secondary index table, Rowkey is formed according to corresponding Rowkey in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, property value corresponding in secondary index table is that the value of Rowkey and Column Properties in the table of HBase source is formed, such structure can ensure when inquiring about the record meeting certain Column Properties value in the table of HBase source, operation can realize fast and can improve the performance of inquiry, and can ensure that consistance is shown in data in secondary index table and HBase source.
Step 23, if insert (Put) data manipulation or deletion (Delete) data manipulation to HBase source table, the data inserting operation of synchronous HBase source table or deletion data operation are in the secondary index table of correspondence.
In this step, after corresponding secondary index table is shown in establishment and synchronous HBase source, the operation of HBase source table being inserted or being deleted data may be had, therefore, when carrying out data inserting operation or deletion data operation to HBase source table, need the data inserted according to Put function or Delete function or delete in corresponding secondary index table.
Particularly, in Put function or Delete function, increase the parameter of the title of secondary index table corresponding to HBase source table.When carrying out data inserting operation or deletion data operation to HBase source table, extracting Rowkey and the value value of this insertion or deletion data, Rowkey and the Value value of secondary index table is set according to Rowkey and the Value value extracted.According to the parameter of the title of the secondary index table of HBase source table correspondence, Rowkey and the Value value of the secondary index table of setting is carried out update or deletion action.So, can ensure that consistance is shown in data in secondary index table and HBase source.
The present invention creates and shows corresponding secondary index table with HBase source, and the data of synchronous HBase source table are in the secondary index table of correspondence, the all recorded informations in fast query Column Properties value can be realized by this secondary index table, reach the object of high-level efficiency inquiry.
Fig. 3 is the structural representation of the inquiry unit of HBase secondary index table of the present invention, as shown in Figure 3, specifically can comprise:
Judge module, for judging whether HBase source table has corresponding secondary index table;
Creation module, for according to Rowkey corresponding in the row race information in the table of HBase source, column information, Column Properties value and HBase source table, creates and shows corresponding secondary index table with HBase source;
