As of Kettle 5.0, it is possible to create a plugin to provide new Value types: http://jira.pentaho.com/browse/PDI-191

我有一个插件可以添加一个键/值类型（如java.util.Map）：
https：// github。 com / mattyb149 / pdi-valuemeta-map

I have a plugin to add a key/value type (like java.util.Map): https://github.com/mattyb149/pdi-valuemeta-map

和另一个代表图表（使用属性图模型）：
https://github.com/mattyb149/pdi-graph-computing/tree / master / pdi-valuemeta-graphSON

and another to represent a Graph (using a property graph model): https://github.com/mattyb149/pdi-graph-computing/tree/master/pdi-valuemeta-graphSON

如果你想试用它们，这两个都在PDI市场中：）

Both of these are in the PDI Marketplace if you'd like to try them out :)
