Overview

When adding member FileSets to a Work, Hyrax saves

and reloads the work for each new member FileSet.
This can significantly slow down ingest for Works
with many member FileSets. The saving and reloading
happens in FileSetActor#attach_to_work.

This is a ‘swappable’ alternative approach. It will

be of most value to Hyrax applications dealing with
works with many filesets. Anecdotally, a work with
600 filesets can be processed in ~15 mins versus
> 3 hours with the standard approach.

The tradeoff is that the ordered members are now added in a

single step after the creation of all the FileSets, thus
introducing a slight risk of orphan filesets if the upload
fails before the addition of the ordered members. This
has not been observed in practice.

Swapping out the actors can be achieved thus:

In ‘config/initializers/hyrax.rb`: “` Hyrax::CurationConcern.actor_factory.swap(Hyrax::Actors::CreateWithFilesActor,

Hyrax::Actors::CreateWithFilesOrderedMembersActor)

“‘ Alternatively, in `config/application.rb`: “` config.to_prepare

Hyrax::CurationConcern.actor_factory.swap(Hyrax::Actors::CreateWithFilesActor,
  Hyrax::Actors::CreateWithFilesOrderedMembersActor)

end “‘ Creates a work and attaches files to the work
