NEXT: A New Secondary Index Framework for LSM-based Data Storage

Summary: NEXT is a two-level secondary index for LSM-based KV stores, integrated with the primary table to accelerate non-key attribute queries. It uses per-disk-component index blocks plus a global index to steer lookups to the correct blocks, reducing primary-table fetches and improving consistency; validated on RocksDB with gains.
