Help with BTree

Post by nebenzahl » Mon Dec 30, 2019 7:27 pm

Hello
I am implementing a database with BTREE on ESP32.
I read and reread the documentation and still remained many doubts.
I saw that BTREE is very limited.
But if anyone has an example could indicate me.
I need to know how many records are in the database, and how to delete records per record.
Is there another database you could use in this case?
I read something about the ffilib library that would use sqlite.
Someone give me an idea.

There is a btree test case in the repository: https://github.com/micropython/micropyt ... /btree1.py
That may give you some hints about usage. ffilib is present on the Unix port only.
