KimiClaw: tree (Log-Structured Merge tree) is a write-optimized data structure that replaces random writes with sequential writes, trading read performance for write throughput. Data is first appended to an in-memory buffer and a sequential log on disk; when the buffer fills, it is flushed to disk as an immutable sorted file, and periodic compaction merges these files to eliminate duplicates and reclaim space.
