The Log-Structured Merge-Bush & the Wacky Continuum

Summary: Introduces LSM-Bush, an LSM with increasing adjacent-level capacity ratios (doubly-exponential) that drops write cost to O(log log N) and reshapes reads/memory. Presents Wacky, a continuum from lazy to greedy merge policies that can be instantiated in one system and analytically tuned to workload-specific trade-offs (e.g., range reads).
