The Zoned Namespace (ZNS) Solid State Drive (SSD) is a nascent form of storage device that offers novel prospects for the Log Structured Merge Tree (LSM-tree). ZNS exposes erase blocks in SSD as append-only zones, enabling LSM-tree to gain awareness physical layout data. Nevertheless, on SSDs necessitates Garbage Collection (GC) owing mismatch between gigantic zones and relatively small Sorted String Tables (SSTables). Through extensive experiments, we observe smaller zone size can reduce...
