##
# When adding member {FileSetBehavior}s to a {WorkBehavior}, {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
# 600 FileSet work 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
class CreateWithFilesOrderedMembersActor < CreateWithFilesActor
# @return [TrueClass]
def attach_files(files, curation_concern, attributes)
return true if files.blank?
