pebble

Implements backwards links in the memtable skiplist for optimized reverse iteration, a noted improvement over RocksDB in the Advantages section.

Features a faster commit pipeline that achieves better concurrency, enhancing performance under heavy write loads compared to RocksDB.

Intentionally omits less critical RocksDB features, resulting in a smaller, more approachable codebase that is easier to maintain and understand.

Includes range keys API and block-property collectors, enabling efficient range-based data management and iteration skipping for modern workloads.
