Other documents in first identical document.Wherein, the first identical document refers to the identical document of document name, although the first data file
In a certain document and the second data file in a certain document may document name it is identical, but very possible document content occurs
Variation, therefore in order to guarantee that using data be latest data, latest data can be determined using timestamp, and only retain
The latest data of the determination, it can guarantee the integrality of data, it can also be ensured that the timeliness n of data further also avoids
Data redundancy.
For example, multiple documents in the first data file include:
Document A (0)；Document B (0)；Document C (0)；Document D (0)；
Multiple documents in second data file include:
Document B (t1)；Document E (t1)；T1=current time subtracts 1 year
Wherein, the numerical value in () is timestamp；
Since t1 is greater than 0, for the document B (0) and document B (t1) in the first identical document, delete document B
(0), reserving document B (t1).
307, in wire module 102 when the search service data of the new version load completion, by searching for the legacy version
Rope service data is offline, and starts the search service data of the new version, to provide described search service.
If only detecting the first data file, after the completion of the corresponding new version load of the first data file
With legacy version is offline, and start new version to provide search service, realize data under the premise of normal operation and update,
And if concurrent simultaneously two kinds of update modes, i.e. full dose updates and incremental update, then can when full dose updates load and completes,
The processing and load for carrying out incremental update again are restarted after the completion of incremental update also loads by full dose update and incremental update
Corresponding new version, to provide described search service.
308, when off-line module 101 receives the real-time stream that the user sends, by the real time data flow point
It is not loaded onto the new memory space and original memory space.
This mode loaded respectively can to get latest data in new memory space, although real-time stream
May be updated in full dose or incremental update during pour into, however, it is possible to guaranteed by way of timestamp data when
New property, the document in the real-time stream can add third timestamp, and the third timestamp is used to indicate current time, makes
It obtains in follow-up data integration process, maximum document can be stabbed with retention time, ensure that temporal sequencing.
309, according to of document in the timestamp and the real-time stream of multiple documents in the new memory space
Three timestamps determine that the new memory space neutralizes the second identical document in the real-time stream, retain described second
The maximum document of timestamp in identical document deletes other documents in second identical document.
In another example multiple documents in the first data file include:
Document A (0)；Document B (0)；Document C (0)；Document D (0)；
Multiple documents in second data file include:
Document B (t1)；Document E (t1)；T1=current time subtracts 1 year
Multiple documents in real-time stream include:
Document B (t2)；Document F (t2), t2=current time
Wherein, the numerical value in () is timestamp；
Since t2 is greater than t1 and 0, for document B (0), document B (t1) and the document B in the second identical document
(t2), document B (0), document B (t1), reserving document B (t2) are deleted.
By carrying out the processing of new full dose data on one side in data updating process, original full dose data are used on one side
Search service is provided, can realize the update of data, the process is not only in the case where not influencing search service and operating normally
