Your triggers have to be stored.  Every time they’re activated (each time you 
insert a row) they have to be run.  That requires SQLite to grab enough memory 
and/or disk space to run the triggers and to construct any temporary indexes 
they require.

Also, it’s a nightmare to debug in comparison with just creating one extra 
index.
