Get all keys?

[Shuhao]

Is it possible to list all keys in a db?

Thanks,
Shuhao

Hi,

One way is with an unbounded iterator. You can pass it a flag s.t. it only returns keys, otherwise it returns a (key, value) 2-tuple.

import leveldb

db = leveldb.LevelDB('./db')

db.Put('hello', 'value')

db.Put('world', 'value')

for k in db.RangeIter(include_value = False):

print 'K', k

Regards, Árni Már
