PickleShare - a small 'shelve' like datastore with concurrency support
|
||
|
|
|
||
|
|
Like shelve, a PickleShareDB object acts like a normal dictionary. Unlike shelve,
|
||
|
|
many processes can access the database simultaneously. Changing a value in
|
||
|
|
database is immediately visible to other processes accessing the same database.
|
||
|
|
|
||
|
|
Concurrency is possible because the values are stored in separate files. Hence
|
||
|
|
the "database" is a directory where *all* files are governed by PickleShare.
|
||
|
|
|
||
|
|
Example usage::
|
||
|
|
|
||
|
|
from pickleshare import *
|
||
|
|
db = PickleShareDB('~/testpickleshare')
|
||
|
|
db.clear()
|
||
|
|
print("Should be empty:",db.items())
|
||
|
|
db['hello'] = 15
|
||
|
|
db['aku ankka'] = [1,2,313]
|
||
|
|
db['paths/are/ok/key'] = [1,(5,46)]
|
||
|
|
print(db.keys())
|
||
|
|
|
||
|
|
This module is certainly not ZODB, but can be used for low-load
|
||
|
|
(non-mission-critical) situations where tiny code size trumps the
|
||
|
|
advanced features of a "real" object database.

||
