Adapter Service Processing
To use Adapter for Apache HBase, you create adapter services. Adapter services allow you to connect to the adapter's resource and initiate an operation on the resource from Integration Server
You call adapter services from flow or Java services to interact with HBase. The adapter services perform database operations by calling Apache HBase Java API. Integration Server then uses adapter connections that you defined earlier to execute the adapter services. For details, see Adapter Service Processing.
Adapter services are based on templates provided with Adapter for Apache HBase. Each template represents a specific technique for doing work on a resource, such as using the Retrieve service template to retrieve specified information from the database
An adapter service template contains all the code necessary for interacting with the resource but without the data specifications. You provide these specifications when you create a new adapter service.
Creating a new service from an adapter service template is straightforward. Using Software AG Designer, you assign the service a default adapter connection.
After you select the connection for the adapter service, you select the adapter service template and supply the data specifications using Designer. Some familiarity with using Designer is required. For more information, see the webMethods Service Development Help for your release.
Adapter for Apache HBase provides the following adapter service templates:
Adapter Service Template
Description
Retrieve Operation Service
Retrieves records from HBase table and returns the values of column qualifiers of those records.
For instructions about configuring the service, see Configuring Retrieve Operation Service.
Delete Operation service
Deletes a specific row, column family, or column qualifier completely from a selected table.
For instructions about configuring the service, see Configuring Delete Operation Service.
Upsert Operation service
Either inserts the records into or updates the records of an HBase table. If the record does not already exist, it is inserted. If the record exists, it is updated.
For instructions about configuring the service, see Configuring Upsert Operation Service.
Retrieve Operation With Comparator service
Retrieves records from HBase table and returns the values of column qualifiers of those records based on the provided filters, standard set of compound operators, and comparators form hierarchical queries.
For instructions about configuring the service, see Configuring Retrieve Operation With Comparator Service.
