Python bindings for LevelDB

author: Arni Mar Jonsson ([email protected])

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)
>>>
