Migrate Redis data on Amazon ElastiCache
"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).
The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.
Requires Redis 2.8.0 or higher.

EMPMYMIP: Easily Maintain a PyPI Mirror of Your Important Packages!

Status

EMPMYMIP seems to mostly kind of work for me. It might even do the same for you!

The implementation is kind of a huge hack, though, and it might very well

Python module for interacting with rtorrent's XML-RPC interface directly over SCGI.

# rtorrent_xmlrpc
# (c) 2011 Roger Que <alerante@bellsouth.net>
#
# Python module for interacting with rtorrent's XML-RPC interface
# directly over SCGI, instead of through an HTTP server intermediary.
# Inspired by Glenn Washburn's xmlrpc2scgi.py [1], but subclasses the
# built-in xmlrpclib classes so that it is compatible with features
# such as MultiCall objects.
