# MetaVox Load Test - Hoofd Playbook
# =============================================================================
# Maakt teamfolders, metadata-velden, bestanden en metadata-records aan op een
# Nextcloud-instantie met MetaVox.
#
# Gebruikt directe filesystem writes en MySQL inserts i.p.v. WebDAV/API
# voor maximale snelheid (~500K bestanden + ~43M metadata records in < 2 uur).
#
# Gebruik: ansible-playbook -i inventory/hosts.yml site.yml
# Tags:    precheck, teamfolders, metadata-fields, files, db-register,
#          folder-structure, drop-indexes, metadata-records
