Database

Information about recognized faces is stored in the Hits table.

When an event of recognition occurs, an entry in the Hits table is added to match a captured face identifier in the FIRS table with reference face identifier in the Persons table.

• Face search first connects to the database, reads the data set, compares it, and saves the result. This is the slowest search process.
• Metadata, images and vectors are stored in the database. As a consequence, the database quickly overflows and begins to be automatically cleaned, which does not provide sufficient storage depth.

• At startup, the server reads all the data from the folder into memory and performs the search. Further the received data are written to the memory, to the database and to the folder. This is the fastest search process.

• All search is carried out in operative memory. As a consequence, there is a high memory consumption and a longer server start.

• Metadata, images and vectors are also stored in the database. As a consequence, the database quickly overflows and begins to be automatically cleaned, which does not provide sufficient storage depth.

• Metadata is stored in the database, but images and vectors are stored only in the folder on disk. As a result, the database overflows slower and provides maximum storage depth.
