How to access a static uploadet file?

[flomickl]

Hi
yet another develop question.
Imagine a user has uploaded a file.
Would it be possible to access this file in a processor somehow?
In the past, I used this to access a DB entry:
https://streampipes.apache.org/docs/docs/extend-sdk-static-properties.html#runtime-resolvable-selections
Is this still up to date or are some new methods implemented?

The workflow for the user would be something like:

1. Upload a file via file manager
2. Create a pipeline and select this specific processor
3. Select the file and maybe a property selection from the file and use it in the processor. Potentially add it to the stream as well.

Hi @flomickl,

you can upload files as part of the processing element configuration. See CsvMetadataEnrichment as an example [1].
In the declareModel you can use requiredFile.
Is this the behavior you are looking for?
