SSDB – A leveldb server with zset data type
Views: 20555 | No CommentsThe Google leveldb is just a c++ library, cannot be directly used by PHP/Java/Python. As it is a library, data can’t be accessed across multi machines(not even multiprocesses in one machine).
SSDB(or zdb) is a network server that wrapping leveldb library, more important, besides key-value data type, SSDB supports zset(sorted set) and hash data type. Zset is the most valuable data type that widely used with Redis, to describe business abstracts such as inbox/outbox of a messaging system, posts list of a news site, etc.
SSDB’s client APIs currently including PHP, Python, Cpy, and more can be added easily.
Here is a list of SSDB features:
- Network wrapping of Google leveldb, client-server supports
- Persistent key-value, key-zset, key-hash storage
- Very fast(benchmark)
