Lastest release
A memcached based cache for any store used with tiddlyweb. Decorates an existing store, wrapping a defined store, caching retrieved objects.
To make use of this store, there are several software and administrative requirements. This is fairly complex stuff so don't expect to be able to just turn it on and make it go.
You must have:
a memcached server
the python-memcached module
the following changes to your tiddlywebconfig.py:
- config = {
# set the server_store to be the caching.py module 'server_store': ['tiddlywebplugins.caching', {}], # the host and port of one or more memcached servers. # this is separate from server_store in case there are # other things that want to use a memcached server 'memcache_hosts': ['127.0.0.1:11211'], # the configuration of the base store which is # being cached by the caching store. Its structure # is the same as server_store. 'cached_store': ['text', {'store_root': 'store'}],
}
If you run this code against the TiddlyWeb core tests you should be aware that some of them will fail because the cache is not flushed between runs, so sometimes there are incorrect values in the cache.
If you choose to use this in a production environment you will need to write some scripts which start, stop or clear the memcache cache upon each fresh start of the server. You must also keep in mind that if you edit data in your on disk store by hand, you need to remember to invalidate the in RAM cache through some mechanism.
