Subject [jira] [Commented] (AIRAVATA-819) Support the workflows with ForEach inputs to get inputs from file

Suresh Marru commented on AIRAVATA-819:
---------------------------------------

Heshan I agree this is a needed capability. For API usage, this will be trivial, because the
client which calls the API can read such kind of a file and pass the comma seeprated values.
How do you propose this XBaya? Add a new helper component?

> In case of a usecase like gene sequence alignment, you might give 1000s of gene sequences
as the input. In a situation like that, what we have to do is to have comma separated string
with the inputs. In my usecase, it's not practical because a single sequence strand is having
a substantial length. Therefore, I think it'll be easier for the user, if we provide a mechanism
where the user can give the input as a file and instead of the comma delimiter, we could use
a "new line". 
> This is something which I felt needed when doing some testing with the EC2Provider.
