Expecting for namespace of key and native expiring support about flask-kvsession

[flexd]

I agree it should be possible to namespace the keys.

Currently you just end up with a massive list of randomly generated keys.

[mbr]

As of simplekv 0.9.2, this can be achieved using PrefixDecorator:

store = ...  # setup store normally
prefixed_store = PrefixDecorator('sessions_', store)

# ...

KVSessionExtension(prefixed_store, app)

The decorator will transparently prefix sessions_ to every session key stored and strip it upon retrieval. See the simplekv docs for details.
