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

FindFace uses the following data storages:

* Tarantool-based feature vector database that stores face feature vectors and recognition events.
* PostgreSQL-based main system database ``ffsecurity`` that stores internal system data, records, and user accounts. 
* The ``/var/lib/findface-security/uploads`` directory that stores photos uploaded to records, video files, full frames of events, and thumbnails.
* The ``/var/lib/ffupload/`` directory that stores such event artifacts as normalized face images. 

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

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

* ``ffsec_face_events``: feature vectors extracted from faces detected in the video.
* ``ffsec_face_objects``: feature vectors extracted from face images uploaded to the card index.
* ``ffsec_face_clusters``: centroids of face clusters.
