The article starts with a job‑interview anecdote and then provides a comprehensive overview of NoSQL, its history, definitions, comparison with MySQL, practical scenarios, and detailed examinations of key NoSQL projects such as LevelDB, RocksDB, SSDB, and Pika, highlighting their architectures and use cases.
Learn how to design and implement a robust proxy IP pool for distributed web crawlers using Python, Flask, and SSDB, covering proxy acquisition, quality testing, storage, API services, scheduling, installation, and usage examples to ensure fast and stable crawling.
A benchmark on a test server comparing Redis and SSDB using one million SET, GET, HSET, and HGET requests with 1,000 concurrent clients shows SSDB delivering far lower QPS than Redis, contradicting the performance figures advertised by SSDB.
SSDB is a high‑performance NoSQL database compatible with Redis, offering rich data structures, LevelDB storage for terabyte‑scale data, multi‑language client support, and features like replication and load balancing, positioning it as a viable Redis replacement for large‑scale applications.
