This recipe illustrates how to use the composite datasource processor to build a random report generator.
- Random-Report-ElixirSamples.ds
- It starts off using a FileSystem DS to read in all the files within a repository.
- This dataset is then filtered to return only the rml files.
- A JavaScript variable ( count ) is used to register an ID to each record.
- Sequence-Number.dsThis ds receives a count value to return a count of random data ( a random number, and a random value based on Mime-Type-Extension.ds).
- We will use a lookup processor to form a set of data which consists of the “File-Extension”/“Mime-Type”/“Seq_Num”.Note: There is an additional dev processor to return the “seq_num” from equence-Number.ds
- The 2 flows of data are then joined together by the “Seq_Num”.With this composite datasource, you now have a random generator which is based on a filesystem, e.g ElixirSamples. You can control the return output count via parameter and return you the target output file (i.e it’s mime-type and file extension)
- This set of data can now be based to the Activity.Job to trigger the report generation.
