# frozen_string_literal: true
# Entry point of the BulkImport feature.
# This service receives a Gitlab Instance connection params
# and a list of groups to be imported.
#
# Process topography:
#
# sync | async
# |
# User +--> P1 +----> Pn +---+
# | ^ | Enqueue new job
# | +-----+
#
# P1 (sync)
#
# - Create a BulkImport record
# - Create a BulkImport::Entity for each group to be imported
# - Enqueue a BulkImportWorker job (P2) to import the given groups (entities)
#
# Pn (async)
#
# - For each group to be imported (BulkImport::Entity.with_status(:created))
# - Import the group data
# - Create entities for each subgroup of the imported group
# - Enqueue a BulkImportService job (Pn) to import the new entities (subgroups)
