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)

>>>
