Hi,
even with the latest pull request about asynch init, the importer REST api is
still a bit cumbersome to use, in that at least two asynch calls (and the associated
state tracking) need to be made in order perform a successful import.
In this mail I’m proposing a new import mode in which a single call is made, where
the creation results in the process to be run immediately, as soon as the init phase
is complete.
Of course this assumes the input data is good and that the tasks are created succesfully,
which is often the case in fully automated setups.
The idea is that the initial POST creating the process can have not only an async=true
paramete, but also a execute=true one that will make the import start immediately.
Code wise, I was thinking of calling Importer.runAsynch(…), which in turn would check if
there is any task in the context, and if not, would transparently perform the init phase.
This would work best with the default transformations idea proposed in the last round of mails,
allowing the caller to attach predictable transformations to all generated tasks, without
having to go over them one by one.
What do you think? This should make the importer a bit easier to use outside of the interactive
use cases that it was initially designed for.
Cheers
Andrea
