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

FindFace Security uses the following data storages:

* Tarantool-based biometric database that stores biometric samples (feature vectors) and face 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, face thumbnails, and normalized face images.
* Directory ``/var/lib/ffupload/`` that stores only such event artifacts as face thumbnails. 

Biometric Database Galleries
------------------------------------

There are 3 galleries in the Tarantool-based biometric database:

* ``ffsec_dossier_face``: biometric samples extracted from dossier photos.
* ``ffsec_events``: biometric samples extracted from faces detected in the video.
* ``ffsec_persons``: centroids of persons (virtual biometric samples averaged across all person's faces) and metadata.
