Embodiment
The present invention provides a kind of data interchange platform, applied to computer realm.The method technical characterstic mainly includes：
Integrated kettle, kettle platforms are the bases of whole system, including plug-in management, metadata management and data integrating engine；
Task scheduling is realized based on Quartz frames, quartz clusters can give scheduler by failover and the function of load balancing
High availability and retractility are brought, is mainly used to perform timed task, such as：Timing performs connection, and timing performs service
Docking, timing perform file docking, periodically go issuing service etc.；Service centre's service note is realized using Dubbo micro services frames
Volume, service request, the function of service call；It is adapted to big data platform, there is provided parallel data extracts conversion function.
Below by drawings and examples, technical scheme is described in further detail.
As shown in Figure 1, being the Technical Architecture figure of data interchange platform of the present invention, data are included from data source to destination end
Source, the adaptation of destination end, passage time stamp, flag bit, log analysis etc. carry out increment judgement, utilize data filtering, data road
Data processing is carried out by plug-in units such as, data correlations, which is realized by kettle platforms and ETL instruments, is finally based on
The configuration that the task scheduling engine of Quartz completes whole task performs.There is provided unified monitoring management, including system pipes at the same time
The functions such as reason, switching task monitoring, switching task statistics, metadata management and log management.Data sharing combination enterprises service
Bus realizes unified service registration management and service-seeking.In these modules, adapter supports self-defined, extraction increment mark
Will open interface configures, and self-defined plug-in extension is supported in data processing.
In the present embodiment, the adapter of data source protocol adaptation layers is responsible for source system and the data of other application system are handed over
Change, support the various data acquisition modes such as real-time, timing, state triggering；Support the data acquisition of multiple data sources, including
The diversified forms such as webservice, database, file, socket, bigdata, http, rest, while support plug-in type to extend
Acquisition mode.
In the present embodiment, the step of ETL flows mainly include data pick-up and data processing, data pick-up is as follows：
A1) according to timestamp field in table, selection need to extract data, and incremental data extracts；
A2) design logo position, judges whether data are decimated according to flag bit, to avoid repetition extraction；
A3 trigger) is established in the table of source, new data major key be recorded into interim table, by the contrast with source table, is carried out
Data are synchronous.
Data processing step is as follows：
B1 logic verify) is carried out to data, wrong data deposit is found out and specifies table；
B2) data are route, and data are sent to destination address by Routing Protocol；
B3) data correlation, multiple tables of disparate databases are realized using the database join operations in kettle platforms
Association.
In the present embodiment, kettle platforms are the bases of whole system, including plug-in management, metadata management and data
Integrating engine.Metadata management engine management ktr, kjb or metadatabase, plug-in unit obtain essential information by the engine.Insert
Part management engine is mainly responsible for the registration of plug-in unit.Data integration engine is responsible for calling plug-in unit, and returns to corresponding information.
In the present embodiment, the switching task scheduling feature use task scheduling instrument Quartz that increases income realizes task management.
Quartz be one completely by written in Java task scheduling of increasing income frame, pass through trigger and set operation timing operation to advise
Then, the run time of operation is controlled.Quartz clusters can bring height by failover and the function of load balance to scheduler
Availability and retractility.Quartz provides extremely wide characteristic such as persistence task, cluster and distributed task scheduling etc., at the same time
It is advantageously integrated Spring.For one scheduler example before database manipulation is performed, it is right in QUARTZ_LOCKS tables to first have to obtain
The row level lock answered, obtains the database manipulation that can perform after locking in other tables, and with the submission of operation affairs, row level lock is released
Put, obtained for other Scheduling instances.Each scheduler example follows such a stringent operational procedure.
In the present embodiment, unified monitoring function is monitored the overall process of data exchange.Realize to data traffic and
Inquiry, statistics and the audit of state；Inquiry and monitoring to information exchange service system self-operating state；Information exchange is taken
The remote monitoring of business system.The monitoring of data traffic and state, is to be carried out for all by information exchange service system first
The assurance of the total amount of data of exchange, secondly the microcosmic assurance to each data packet state by information exchange service system.
By monitoring function, may be set in specified time according to projects such as entrance/produce, destination/source place, data volume sizes
Inquired about and counted, so as to fulfill the assurance to total amount；By to data mode (such as etc. it is pending, carrying out, handling
Finish, receipt receives, processing is interrupted) monitoring, can follow the trail of some specify data state.Information exchange is serviced and is
The inquiry and monitoring for self-operating state of uniting, are in order to which whether the operation of confirmation message Exchange Service system itself is normal.Inquiry
Object with monitoring is mainly all kinds of running software entities (such as process, queue etc.) of configuration information Exchange Service system.With
Exemplified by process, the primary operational of monitoring includes query procedure state, stops process, restarting process etc..
As shown in Fig. 2, being data exchange flow process figure of the present invention, data exchange flow process includes：
1) configuration of the adaptation parameter of data source and data destination end；
