Dict-style DBM based on sqlite3.

Project description

Dict-style DBM based on sqlite3.

>>> import sqlite_dbm
>>> db = sqlite_dbm.open(':memory:')
>>> db['foo'] = ['bar', {'baz': 1}]
>>> db['foo']
['bar', {'baz': 1}]
>>> del db['foo']
>>> len(db)
0
>>> db.close()

Fast insert:

>>> db = sqlite_dbm.open(':memory:', auto_commit=False)
>>> for i in range(1000):
...     db[str(i)] = 'foo'
>>> db.commit()
>>> len(db)
1000
>>> db.clear()
>>> db.close()
