module Hyrax
module Actors
# 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
class CreateWithFilesOrderedMembersActor < CreateWithFilesActor
# @return [TrueClass]
def attach_files(files, env)
return true if files.blank?
AttachFilesToWorkWithOrderedMembersJob.perform_later(env.curation_concern, files, env.attributes.to_h.symbolize_keys)
true
end
