List of Storages
-------------------------------

FindFace Multi uses the following data storages:

* Tarantool-based feature vector database that stores object feature vectors and identification events.
* Main system database based on PostgreSQL, that stores internal system data, dossiers, user accounts, and camera settings. 
* Directory ``/var/lib/findface-security/uploads`` that stores uploaded dossier photos, video files, and such event artifacts as full frames, object thumbnails, and normalized object images.
* Directory ``/var/lib/ffupload/`` that stores only such event artifacts as object thumbnails. 

Feature Vector Database Galleries
------------------------------------

There are the following galleries in the Tarantool-based feature vector database:

* ``ffsec_body_events``: feature vectors extracted from bodies detected in the video.
* ``ffsec_body_objects``: feature vectors extracted from bodies in dossier photos.
* ``ffsec_car_events``: feature vectors extracted from cars detected in the video.
* ``ffsec_car_objects``: feature vectors extracted from cars in dossier photos.
* ``ffsec_face_events``: feature vectors extracted from faces detected in the video.
* ``ffsec_face_objects``: feature vectors extracted from faces in dossier photos.
* ``ffsec_user_face``: feature vectors extracted from the FindFace Multi users' photos, used for face-based authentication.
* ``ffsec_persons``: centroids of persons (virtual feature vectors averaged across all person's faces) and metadata.
