-- ImageHub: per-file work TASKS that flow through a dataset's pipeline stages (single-user MVP).
|
|
-- A task is a NEW join row (one per dataset file) carrying its pipeline position (current_stage_id
|
|
-- + pipeline_state), per-user queue status, assignee, priority, and the Ground-Truth reference flag.
|
|
-- The file row itself (imagehub_dataset_files) stays a pure storage record. Membership / multi-labeler
|
|
-- assignment is a later phase, so for now task access reuses the dataset owner-or-admin gate.
|
|
-- Idempotent (CREATE ... IF NOT EXISTS) so the startup runner can apply it to volumes that predate it.
|
|
-- Apply after 020 (no semicolons inside comments or string literals — the runner splitter is naive):
|
|
-- docker exec -i initiative-postgres psql -U initiative -d initiatives < be0/migrations/021_imagehub_task_pipeline.sql
