Definitely 70%, LSM trees are super efficient!

I vaguely remember a discussion about ZSTD and its efficiency, but I can't confidently say if it's 70% or lower.

I feel like I saw somewhere that LSM trees can help with compression, but I can't recall the maximum storage savings. Maybe it's 60%?

I think I practiced a question similar to this, and I want to say it was around 50% storage savings, but I could be mixing it up.

I remember reading that Zstandard can achieve high compression ratios, but I'm not sure about the exact percentage for PolarDB.

Ah, I've seen this type of question before. I've got a good strategy for working through these.

Hmm, I'm a bit confused by the terminology here. I'll need to review my notes on TDTM and trigger handlers.

I remember reading that Cisco Tetration can identify unusual user behaviors, but I'm not sure which specific pattern it focuses on.
