Thread: [Beginner Question]What should I do if I want to achieve lsm-tree index in postgresql?

Hi community,
I am a student and I want to achieve lsm-tree index in postgresql, for my database experiment,
I have already read the document of postgresql, and some postgresql's moudle source, but I really don't know where to start this work.
Make a new extension like 'https://github.com/HypoPG/hypopg'? Or directly change the kernel?
Can someone give me some advice?
Thanks in advance!

Yours,
Wen Yi
