Introduction

Metadata acceleration is a storage engine performance acceleration feature developed by Huawei and optimized based on RocksDB.

RocksDB is a high-performance, persistent, and embedded key-value storage engine. It is widely used in large-scale data storage and processing, such as Internet services, distributed systems, and data analysis services. Based on RocksDB, the metadata acceleration feature uses a Huawei-developed algorithm to enable Kunpeng acceleration for better storage performance. This feature fits well with the Kunpeng architecture to optimize read and write hotspots, adjust background tasks (data flushing and compaction) based on service loads, and optimize cache logic based on data hotspots.
