shove 0.3.1

Common object storage frontend

Common object storage frontend that supports dictionary-style access, object serialization and compression, and multiple storage and caching backends.

Currently supported storage backends are:

• Amazon S3 Web Service

• Berkeley Source Database

• Apache Cassandra

• Memory

• Filesystem

• Firebird

• FTP

• DBM

• Durus

• Microsoft SQL Server

• MySQL

• Oracle

• PostgreSQL

• Redis

• SQLite

• Subversion

• Zope Object Database (ZODB)

Currently supported caching backends are:

• Memory

• Filesystem

• Firebird

• memcache

• Microsoft SQL Server

• MySQL

• Oracle

• PostgreSQL

• SQLite

The simplest shove use case is:

from shove import Shove

store = Shove()

which creates an in-memory store and cache.

The use of other backends for storage and caching involves passing an module URI or existing store or cache instance to shove following the form:

from shove import Shove

<storename> = Shove(<store_uri>, <cache_uri>)

The module-specific URI form is documented in its module. The URI form follows the URI form used by SQLAlchemy:

shove fully implements the Python dictionary/mapping API:
