It is a toy version, and only supports integers now. I write the code after reading the tutorial in 500 lines, but mine implementation is different from it. However, I also use binary tree for simplicity. I don't have enough time.
python main.py test.db set 12 100
python main.py test.db get 12
python main.py test.db del 12
slow…. it takes more than 2s to insert 10000 records
