SQLite Autoincrement
https://www.sqlite.org/autoinc.html
The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. It is usually not needed. In SQLite, a column with type INTEGER PRIMARY KEY is an alias for the ROWID (except in WITHOUT ROWIDtables) which is always a 64-bit signed integer.
