Disco: A Compact Index for LSM-trees

Summary: Disco indexes all keys in LSM-trees, a compact index that avoids per-run scans with compact key representations to reduce comparisons and I/Os. Queries incur at most one I/O to runs, delivering near B+-tree read efficiency and retaining write performance. (summarized by gpt-5-nano on Feb 09 2026)
