    Default Cassandra Input and paramters

    I want to use Cassandra Input step using CQL , but using the dynamic paramters. Considering the example http://wiki.pentaho.com/display/BAD/...From+Cassandra, I would need to determine the url column name dynamically from another step in Kettle as opposed to hard coding in Cassandra's Input step. I am wondering if there are any recommendations or examples?

    It will be useful to have the ability to bind the field values from previous step (similar to 'Insert data from step' option for Table Input, e.g., http://type-exit.org/adventures-with...-a-k-a-kettle/) for the Cassandra Input step.

    Hi,

    Variables are supported in the CQL query, so you could use a parent job to set these dynamically. Binding incoming field values to variables or placeholders is not supported however.

    Cheers,
    Mark.
