TiddlyWeb store using Redis

Project description

Experiment with using redis as a store for TiddlyWeb.

You must be running a redis server for the tests to pass. The 'redis' module
for Python is required. If you have hiredis, parsing will be improved.

This code supports the full StorageInterface, including policies and
tiddler revisions.

It makes no assumptions about how you are managing your redis server.
You will need to start that, and if you use any non-default configuration
you will need to put that in tiddlywebconfig.py. For example if you want
do use db 5, then you could have:

config = {
'server_store': ['redisstore', {'db': 5}],
}

!ToDo

* Consider using r->keys('tid:1:*') and similar to gather keys for
deletion. This may not be ideal though, as matching for keys when
there are many may be expensive.

* Dealing with keys that might have ':' in them.

* Manage keys that operate as reverse indexes for things we might
like to index_query, such as modifier, tags and fields. This has
not been done thus far as diddling with that would distract from
getting the core set of keys in place.

* Consider reverse indexes for things like bags in recipes, and
users in policies. (Such things have been useful in TiddlySpace).
Again these are not yet done so as to maintain focus.

* See what the options are for pub/sub.
