None.
The database servers will periodically run a job to schedule a Sync operation for those users that are active users of Firefox Home. These jobs are submitted to a RabbitMQ server and picked up by the 'Syncer' component. These tasks only contain the username to be synced.
 
(Idea: Many users try out a new service and then forget about it. We could proactively delete user's data when they do not use Firefox Home for a certain period of time. Note that in the first couple of releases of Home there will not be any user generated data, just a copy of your existing Sync Data. So this is less scary than it sounds.)


=== Home Memcache Servers ===
=== Home Memcache Servers ===


The memcache servers are used to cache frequently used data to make the web app as responsive as possible. Initially just Web Application session objects are stored in memcache. These sessions are user specific Python objects that contain user specific cached data. (Not sure what will actually be in there)

(Not sure what will actually be in there. Possibly fragments of JSON or HTML or lists of things that we generate from your bokomarks & history)

=== Home Syncer ===
The 'Syncer' is a component that implements a sync client. It listens to a RabbitMQ queue to grab sync tasks and runs sync sessions.
The task that it gets from RabbitMQ contain just the username. This means that the Syncer will have to access the Home Database Servers to obtain the access token for the Crypto Proxy.
It will then run a sync session for the specific user against the Sync Proxy and store the synced data (bookmarks, tabs, history) in the Home Database Servers,
