part #34

Hi, @devillove084, thanks a lot for your effort. However, I have some concerns that we are not heading in the right direction. Translating every Java class into a trait and using Box<dyn Trait> doesn't seem ideal to me now. I'm wondering if it's possible to implement a real file index struct first and then consider how to expose them.

I must admit that this additional work stems from my own lack of engineering rigor. Given the current situation, the entire system design needs to be approached from the ground up. I agree with your perspective, and I think it’s best to start by focusing on the specific details. Therefore, I’ll close this PR and redesign it with a dedicated BitMap index and BloomFilter index in mind.

Thank you for taking the time to review it—I’ve learned a great deal from your feedback.

Close it and move on!
