Internal Variables

The following variables are always defined:

Variable Name Sample Value
Internal.Kettle.Build.Date 2010/05/22 18:01:39
Internal.Kettle.Build.Version 2045
Internal.Kettle.Version 4.3

These variables are defined in a transformation:

Variable Name Sample Value
Internal.Transformation.Filename.Directory D:\Kettle\samples
Internal.Transformation.Filename.Name Denormaliser - 2 series of key-value pairs.ktr
Internal.Transformation.Name Denormaliser - 2 series of key-value pairs sample
Internal.Transformation.Repository.Directory /

These are the internal variables that are defined in a job:

Variable Name Sample Value
Internal.Job.Filename.Directory file:///home/matt/jobs
Internal.Job.Filename.Name Nested jobs.kjb
Internal.Job.Name Nested job test case
Internal.Job.Repository.Directory /

These variables are defined in a transformation running on a slave server, executed in clustered mode:

Variable Name Sample Value
Internal.Slave.Transformation.Number 0..<cluster size-1> (0,1,2,3 or 4)
Internal.Cluster.Size <cluster size> (5)

In addition to the above, there are also System parameters, including command line arguments. These can be accessed using the Get System Info step in a transformation.

Additionally, you can specify values for variables in the Execute a transformation dialog box. If you include the variable names in your transformation they will appear in this dialog box.
