How to filter file with multiple pattern

How to filter file with multiple pattern

Contributor

Currently i am having simple dataflow which has ListFile-->FetchFile-->PutS3. This flow reads data from source and uploads it to S3. 

Now, i have source directory /users/data/ which has abc_mmddyyy.pdf, xyz_mmddyyy.pdf and hij_mmddyyyy.pdf which uploads into S3 folder \aws\data\ .

We are planning to source new files which would be published in /users/data/demo/www_mmddyyyy.csv and has to be uploaded to \aws\data\demo.

 

How will i achieve this @stevenmatison

@Gubbi Simplest method would be to create a separate ListFile-->FetchFile-->PutS3 flow.   However you should be able to grab everything with the same ListFile processor.  For a single flow you would add updateAttribute to set path you want to use in PutS3.  For example if you see "demo" in the source of the original file, set path to append "demo\".  If not, leave it as " \aws\data\".     You could also use a RouteOnAttribute to send each data type to different PutS3.

 

If I was doing this myself I might start initially with separate flows which I clearly know are operating as expected.    Then I would start on a third dynamic single flow that achieves the results of both.
