The thin Kettle JDBC driver allows a Java client to query a Kettle transformation remotely using JDBC and SQL.
Available from Kettle v5.0-M1 or higher.
As with most JDBC drivers, there is a server and a client component to the JDBC driver.
The server is designed to run as a Servlet on the Carte server, the Pentaho Data Integration server or Pentaho Business Analytics platform. At the time of writing only Carte is supported.
