Pentaho Data Integration (PDI) and Report Designer Manipulation with Parameters
Category: cassandra, pentaho, kettle, report-designer, pentaho-design-studio
I've been trying to tackle the following issue in Pentaho BI suite:
I have a data integration step that returns a column with
n values. I want to pipe that data integration into pentaho report designer and pass that column as a parameter. I then want to convert that column into an array of all string values in the column so that I can pass it as a parameter into another data transformation.
Here is the example. Assume that the first transformation returned the following column
What I am looking to to is to transform this result into array
['abc','edf','hig']. To do so I assign hidden String parameter
event inside report-designer to this column. Then keeping in mind that I want a single array object I created second hidden parameter Object
output with the postprocessing formula
=CSVARRAY([event];0;",";). Now if I pass my second parameter
output to the second transformation, which is a cassandra input, I get empty result back.
Could anyone suggest a good solution?
