# 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 BulkImports::CreateService job (Pn) to import the new entities (subgroups)
