The embodiment of the present application provides a kind of method of data synchronization of relevant database to Hadoop database, the relationship type
The method of data synchronization of database to Hadoop database can be applied in computer equipment shown in figure 1, the computer
The particular hardware form of equipment has very much, for example, data control platform, data control platform is a big data platform, can be with
Data control is carried out to multiple business sides of access.
As shown in Fig. 2, method of data synchronization provided by the embodiments of the present application includes:
S21, basis are directed to the pre-stored invariant parameter in business side to be synchronized and its configuration data, identify the industry
Invariant parameter in each table of the relevant database of business side, and the invariant parameter identified is configured；
It will be appreciated that there are many relevant databases, i.e. the type of relevant database have it is multiple, for example, Oracle
Database, MySql database, PostgreSQL database, Hive database etc..There is a corresponding pass in each business side
It is type database, the type of different business sides, relevant database may be different.
It will be appreciated that Hadoop database, i.e. HadoopDatabase, abbreviation hbase, hbase are a distributions
, PostgreSQL database towards column, hbase is different from general relational database, it is one and is suitable for unstructured data
The database of storage.
It will be appreciated that there are many parameters of the relevant database of business side to be synchronized, for example, metadata table name,
Literary name section, data validity interval, locking range, major key, increases the parameters such as field, the method for synchronization at field type certainly.To relationship type number
Before synchronizing according to library progress data, need to configure these parameters.Due to table different in relevant database, parameter
May be different, therefore in the prior art, it is to design a synchronization scheme, workload for each table in relevant database
It is huge.However, taking different processing modes in this application: invariant parameter is pre-configured, it is mentioned for variable element
Interface is modified for corresponding configuration data, for user's manual configuration.
It will be appreciated that invariant parameter and variable element are not unalterable, the application of business side difference, business side
Scene difference etc., invariant parameter and variable element may be different.So-called invariant parameter refers to for each table, has
The configuration data of parameters is fixed a bit, these parameters are invariant parameter, and the configuration data of some parameters is may to occur
Variation, these parameters are variable element.Under certain application scenarios, the invariant parameter of relevant database may include it is described not
Variable element include in metadata table name, literary name section and field type at least one of, variable element may include data validity interval,
Locking range, major key, from increase in field and the method for synchronization at least one of.
Before carrying out data and synchronizing, it is first determined which parameter is invariant parameter, which parameter is variable element, will not
Variable element and its configuration data are stored in data control platform, and realization is stored in advance.When progress data are synchronous, to relationship type
Each table of database identified, when recognizing parameter identical with any one pre-stored invariant parameter, then
Invariant parameter is had this parameter as, and according to pre-stored corresponding configuration data, which is configured.
For example, including order table and user's table, metadata table name, the literary name of order table and user's table in relevant database
Section and field type will not change, therefore these parameters are invariant parameter, stored in data control platform in advance it is good this
A little parameters.Carry out data it is synchronous when, in relevant database order table and user's table identify, when recognizing first number
When according to this parameter of table name, metadata table name according to the pre-stored data configures the metadata table name recognized.For it
His invariant parameter, configuration process are also in this way, to realize the configuration to the invariant parameter of relevant database.
S22, for the variable element in each table of the relevant database, corresponding configuration data modification is provided
Interface, so that user configures the variable element；And it can be changed ginseng according to described in configuration data modification interface
Several configuration operations, determines the configuration data of the variable element；
In practical applications, the default configuration ginseng of the variable element can be provided in configuration data modification interface
Number；In this way, it is variable that user can modify modification on interface in the configuration data after showing the configuration data modification interface
The default configuration data of parameter.That is, the above-mentioned corresponding configuration data of offer modifies interface, so that user is to described variable
Parameter is configured, can be with are as follows: provides corresponding configuration data modification interface, the silent configuration for user to the variable element
Data are modified.
For example, the variable element of the relevant database of business side to be synchronized include: data validity interval, locking range,
Major key is matched data validity interval by configuration operation of the user on configuration data modification interface from increasing field and the method for synchronization
It is set to 2 months, locking range is configured to the data within nearly 48 hours, and major key is configured to order ID, can be configured to order from increasing
Time field, the method for synchronization can be configured to incremental update or full dose updates.Wherein, each variable element is modified in configuration data
There is default parameters on interface, default parameters can be rule of thumb arranged, can also be with automatic identification, for example, therein from increasing and main
Key can determine default configuration by way of automatic identification, default configuration or according to circumstances be repaired for selection by the user
Change.
S23, determine the relevant database of the business side to the data synchronization level of Hadoop database；
It will be appreciated that in a database, some tables need to update every 1 hour it is primary, some tables need every
It updates once within one day, some tables only need to synchronize once, therefore a database may correspond to multiple synchronization levels.
In practical applications, the synchronous task of different stage corresponds to different data synchronization levels, more in addition to tables of data
New frequency, the factor being contemplated that when determining data synchronization level also there are many, for example, different business sides, business side are different
Business scenario, different methods of synchronization etc., it is thus determined that the process of the data synchronization level can also include: according to the industry
The type of business side, the business side business scenario and the method for synchronization at least one of, determine the data synchronization level.
It, can be according to data synchronization level to the place of each business side when needing to carry out data to multiple business sides to synchronize
It makes sequence in order to be arranged, can be improved synchronous efficiency, reduce influencing each other between different task, and in design synchronization scheme
When can determine when according to data synchronization level carry out data synchronize.
It will be appreciated that there is no sequencing between above-mentioned steps S21, S22, S23, for example, three steps are performed simultaneously,
Synchronous efficiency can be improved in this way.
S24, the configuration data according to the invariant parameter of the relevant database of the business side, the variable element
Configuration data and the data synchronization level, determine corresponding synchronization scheme, and relationship type is executed according to the synchronization scheme
The data of database to Hadoop database are synchronous.
In practical applications, synchronization scheme can be determined using database replication synchronization data software, for example, Kettle is soft
Part.Synchronization scheme is determined, in turn based on the data synchronization level of the parameters, determination that configure before using Kettle software
It is synchronous to execute data.
In practical application, Kettle software can specifically be believed according to the metadata of the relevant database of the business side
Breath, the preset standard table structure of the Hadoop database, the relevant database of the business side and the Hadoop data
Field mapping relations, the configuration data of the invariant parameter, the configuration data of the variable element in library are synchronous with the data
Grade determines corresponding synchronization scheme using database replication synchronization data software.
For example: the corresponding table configuration information of inquiry different data synchronization level uses kettle database group
Part configuration data source information, metadata information etc.；Kettle table reading assembly is used according to data source information；Table data are read,
The synchronization level information of each table in table data, that is, database, for example, database has ten tables, three tables are grade A, three tables
For grade B, four tables are this configuration information of grade C；Said modules are handled according to preset logic flow, including judge item
Part, data flow etc.；The table data read are subjected to Screening Treatment；It will using Hbase operating assembly according to metadata information
Obtained data write-in Hbase table is screened, and then has configured Hbase table and matching field etc., and then according to having configured Hbase table
And matching field determines synchronization scheme.Constant ginseng is all referred to during reading assembly, reading table data, processing component etc.
Number, variable element etc..

It stores into default middle database, so that the configuration data and the data that obtain the invariant parameter in data synchronization process next time are same
Walk grade.
Here, invariant parameter and its configuration data, data synchronization level are stored into default middle database, when later again
The relevant database of the business side extract directly from middle database when data synchronize, without again to constant ginseng
Number is configured, without being determined again to data synchronization level.That is, being not that synchronize will be right for data each time
Invariant parameter carries out configuring and determining synchronization level, and it can be used repeatedly for storage to middle database, data after can be improved in this way
Synchronous efficiency.
Certainly, when the business scenario of relevant database change cause its invariant parameter change when, need again into
Row parameter configuration and determining data synchronization level.
