zstore

An distributed, eventually-consistent KV store built on ZNS SSDs

This project builds the following parts after compilation:

• measurement: we measure the append time, write time, read time, and zone full detection time.
• multipath: we use the multipath support from spdk to understand the reordering caused by running zone append in parallel
• zstore: the distributed, eventually-consistent object store built on ZNS SSDs
