    Views: 13467 | No Comments

    SSDB v1.1.0 is released! This version added the Online Backup feature, which allows to backup a SSDB instance without stopping service.

    Quick Start

    ./tools/ssdb-dump 8888 backup_dir

    A copy of SSDB instance(it is also the leveldb database) will be saved in a new created directory backup_dir.


    Transfer the directory backup_dir to the server on which ssdb-server runs, then edit ssdb.conf to use backup_dir, restart ssdb-server.

    Next Step

    SSDB is now a productional storage server! The next feature that is planning to added is Replication(Master-Slave architecture). Replication is the base of distributed system.

    SSDB – A leveldb server with zset data type

    Views: 20995 | No Comments

    The 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)
