DolphinScheduler Datasource SPI main design

How do I use data sources?

The data source center supports POSTGRESQL, HIVE/IMPALA, SPARK, CLICKHOUSE, SQLSERVER data sources by default.

If you are using MySQL or ORACLE data source, you need to place the corresponding driver package in the lib directory

How to do Datasource plugin development?

org.apache.dolphinscheduler.spi.datasource.DataSourceChannel org.apache.dolphinscheduler.spi.datasource.DataSourceChannelFactory org.apache.dolphinscheduler.plugin.datasource.api.client.CommonDataSourceClient

  1. In the first step, the data source plug-in can implement the above interfaces and inherit the general client. For details, refer to the implementation of data source plug-ins such as sqlserver and mysql. The addition methods of all RDBMS plug-ins are the same.

  2. Add the driver configuration in the data source plug-in pom.xml

We provide APIs for external access of all data sources in the dolphin scheduler data source API module

Future plan

Support data sources such as kafka, http, files, sparkSQL, FlinkSQL, etc.
