Python bindings for leveldb database library
Project description
py-leveldb: Python bindings for LevelDB (http://code.google.com/p/leveldb/) author: Arni Mar Jonsson (arnimarj@gmail.com)
Build Instructions
First of all, you need to build the included leveldb library:
$ ./compile_leveldb.sh
Then, the extension itself:
$ python setup.py build
And, optionally, install it:
$ sudo python setup.py install
Example Usage
>>> import leveldb >>> db = leveldb.LevelDB('./db') >>> db.Put('hello', 'world') >>> print db.Get('hello') world >>> db.Delete('hello') >>> db.Get('hello') Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError >>> for i in xrange(10): ... db.Put(str(i), 'string_%s' % i) ... >>> print list(db.RangeIter(key_from = '2', key_to = '5')) [('2', 'string_2'), ('3', 'string_3'), ('4', 'string_4'), ('5', 'string_5')] >>> batch = leveldb.WriteBatch() >>> for i in xrange(1000): ... db.Put(str(i), 'string_%s' % i) ... >>> db.Write(batch, sync = True) >>>
