As for this topic, I don’t think sqlite3 help any much for this specific 
problem.
The real problem is how to do this for Emacs Lisp, and if we figured this out
any underlying storage will work, either plain text or gdb(m) or sqlite3.

And I don’t think the latter 2 would even provide much performance benefit,
because you will probably print parts of data to string then feed to db anyway.
db doesn’t understand Lisp, it doesn’t solve Lisp problem.
