The present invention is that the image realized based on big data technology is retained, cached and inquired, and has high-throughput, response speed
Fastly, advantage low in cost.
Fig. 1 shows one embodiment of the present of invention, a kind of image storing method, comprising:
S101 server cluster obtains each institution business information (institution business information includes: mechanism number and type of service)
Corresponding cached configuration strategy.
S102 (server cluster loops through each cached configuration strategy) is if current time is located in a cached configuration strategy
Uplink time section when, upload local cache in the corresponding image data of the corresponding institution business information of cached configuration strategy
To presetting database (presetting database is distributed data base)；
If S103 current time is more than the uplink time section in a cached configuration strategy, stop uploading the cached configuration
The corresponding image data of the corresponding institution business information of strategy.
Specifically, mechanism number refers to the unique identification of mechanism (such as: a bank outlets), for specific mechanism into
Row authentication.Type of service refers to the business specifically handled, such as: personal loan, enterprise's monetary transaction, personal monetary transaction
Deng.The type of service that each mechanism supports can be identical, can also be different, such as: it self-service can handle hair fastener, inquiry account information etc..
Image data includes structural data and unstructured data, structural data include: mechanism number, type of service,
Batch information, exchange hour etc., unstructured data include: the picture file of the secondary transaction, video file etc..
There may be differences for each mechanism number cached configuration strategy corresponding with type of service, such as: business is busier
Mechanism cached configuration strategy are as follows: belong to all types of service of this mechanism image data be after local cache 3 days, evening
Upper 10 points just upload to 8 points of morning；The cached configuration strategy of the more idle mechanism of business (substantially without client after at 3 points in afternoon)
Are as follows: belong to the image data of all types of service of this mechanism after local cache 7 days, 8 points to morning of at 3 points in afternoon carries out
It passes.
Server cluster loops through all cached configuration strategies, is confirmed whether to need to upload shadow according to current time
As data to presetting database；If current time, not in uplink time section, no matter whether image data has uploaded, all no longer
It uploads, in order to avoid influence the normal operation respectively traded in mechanism.
Such as: mechanism A is a bank outlets, and bank's working time is 9:00-16:30 points, Monday to Saturday, at this
In period, the client of mechanism A is relatively more, and query information, the frequency of upload information to server cluster are higher, if at this
It waits server cluster and the mechanism A image data uploaded is directly uploaded to presetting database, read and write while carrying out, it can be in certain journey
The response speed for transferring, storing image data in sequence in influence process of exchange, causes mechanism A poor to the usage experience of user.
The corresponding cached configuration strategy of the mechanism number of mechanism A can be pre- to be uploaded to 7 points of every night to 8 points of morning in server cluster
If database, the image data that other times mechanism A is uploaded first is buffered in the local of server cluster.Certainly, mechanism A's is every
A type of service can configure different cached configuration strategies, meet different use demands.
Therefore, the cached configuration strategy and institution business according to different use requirements, in actual conditions server cluster
Information is corresponding, and a server cluster corresponds to several mechanisms, and there are several types of service in a mechanism, can there is multiple cachings
Configuration strategy.
Server cluster loops through each cached configuration strategy, if current time is in the upload of a cached configuration strategy
When time interval, then the corresponding image data of the corresponding institution business information of the cached configuration strategy is uploaded；If at current time
At the uplink time section of multiple cached configuration strategies, then multiple threads is called to upload the corresponding mechanism of each cached configuration strategy
The corresponding image data of business information.If current time is located at uplink time section, but without image data need to upload when,
Then thread suspend mode, when the image data and current time of upload in need are located at the upload in a certain cached configuration strategy
Between section.
Preferably, upload local cache in the corresponding image data of the corresponding institution business information of cached configuration strategy extremely
Presetting database specifically: obtain the batch information of the corresponding institution business information of the cached configuration strategy, and the batch is believed
It ceases corresponding image data and is uploaded to presetting database.
Specifically, batch information includes: batch serial number, it is the unique information mark of every data；Name, gender etc..
Optionally, it can be obtained in batches when obtaining batch information, when upload can be realized batch and upload.Such as: it is primary to obtain
10 batch informations, while uploading this corresponding image data of 10 batch informations.
It should be noted that the unstructured data in a image data can include multiple pictures, video file simultaneously.
Such as: user wants to handle out card, and this time the corresponding unstructured data of batch information of transaction has the positive and negative figure of identity card
Piece, the video file etc. of the face recognition process of user.
The corresponding image data of the corresponding institution business information of cached configuration strategy in local cache is uploaded to present count
Control strategy is used during according to library；Control strategy includes any of the following or a variety of: flow control, data compression, excellent
Select grade control, breakpoint transmission.
Flow control refers to, carries out flow control when uploading to the image data of every kind of type of service, by server according to
It actually uses situation and carries out dynamic or static adjustment.
Data compression refers to, carries out compression of images when migrating to presetting database to one or several file types, by
Server configuration.
Two priority classes refer to, to type of service present on server, carry out arrangement upload according to priority and (refer to simultaneously
When needing to upload), priority is configured by engineer.
Breakpoint transmission refers to, when transmitting more image files, transmission is encountered when unsuccessfully needing to transmit again, only to preceding primary
The file for uploading failure is transmitted again, improves efficiency of transmission.
The equipment of control strategy improves the efficiency that server cluster uploads data, and the higher data of priority can be excellent
It first migrates, protects the safety of significant data.
Preferably, upload local cache in the corresponding image data of the corresponding institution business information of cached configuration strategy extremely
Presetting database specifically:
Structural data in image data is uploaded to default first database；
By the unstructured data in image data according to default screening criteria, it is uploaded to default first database or default
Second database.
Default screening criteria includes any of the following or a variety of: the configuration such as type of service, image modality, format, size
Parameter.
Specifically, default first database is HBASE, Hive distributed column database (peculiar number of big data technology
According to memory module, the data access of high concurrent is supported)；Default second database is HDFS (Hadoop distributed file system),
It can provide the data access of high-throughput, the application being very suitable on large-scale dataset.Image file is this bigger
File data store to HDFS, one comes that file transfer speed is higher, and two carry out user in client query, transfers speed more
Fastly, response speed faster, makes user have good usage experience.
Structural data is smaller, is directly stored in HBASE, does not use HDFS structured data etc. lesser
Data are because the minimum unit of its memory block is larger, if storage small documents, can have a large amount of redundancy and waste, cause to imitate
Rate is low；And unstructured data then needs to carry out selection storage according to default screening criteria, improves the use effect of each database
Rate.
The example of each default screening criteria in actual use is as follows:
Type of service: certain types of service are typically all video file (such as: recording the movement done of user), very greatly,
It can be directly confirmed whether to be stored in HDFS according to type of service.
Image modality: the image modality of certain unstructured datas is video, then it can be allowed to be stored in HDFS, if figure
Piece is then judged according to subsequent format, size again.
Format: certain formats are high definition pictures, and certain formats are video files, and the difference of format represents these data
It is of different sizes, therefore, it can be screened and be stored to corresponding presetting database according to format.
Size: as soon as dividing a boundary, greater than storing to default second database for this boundary, what is be less than or equal to is just deposited
It stores up to default first database.
Default screening criteria is according to the actual situation by engineer's self-setting.
As shown in figure 5, be to store structural data to Hbase, the case where unstructured data is stored to HDFS；Such as
It is the case where all storage structural data and unstructured data to Hbase shown in Fig. 6.
Optionally, after image data is uploaded to presetting database, it is corresponding in local cache to modify the image data
Buffer status.
Specifically, being managed using data cached list to the data in local cache, their buffer status is inquired,
Include: to have cached, had moved (or upload) etc., adjusts according to demand.
In the present embodiment, image data is stored using big data technology, supports the data access of high concurrent, it is real
The efficient storage of unstructured data is showed, and has also laid the foundation for quickly reading.In addition, server cluster is matched according to caching
It sets strategy and uploads the problem of being buffered in local image data, avoiding read-write interference again during idle time, compared to existing tradition
