SQLITE_DBCONFIG_DEFENSIVE
The SQLITE_DBCONFIG_DEFENSIVE option activates or deactivates the "defensive" flag for a database connection. When the defensive flag is enabled, language features that allow ordinary SQL to deliberately corrupt the database file are disabled. The disabled features include but are not limited to the following:
The PRAGMA writable_schema=ON statement.
Writes to the sqlite_dbpage virtual table.
Direct writes to shadow tables.
Kudos, very cool. Maybe instead of 'no disk' something like 'SSD for boot media, no local bulk storage' would be clearer, as I was a little confused by this as other posters below were. It's also a little interesting that the 'High CPU' option has the fewest cores of the three options... Any comments on that?
