The goal of this initiative is to identify uses of the shared RedCache servers and eliminate them. If a key/value store is required, use a sidecar redis or memcached instance as appropriate.
Any keys that will require cross-team coordination to remove should be documented in the RedCache Inventory page in Confluence.
Usage in the Control Panel
Cake Cache
The default Cake framework cache engine for the application is configured to use RedCache.
Mapping
The Mapping component caches mapping lookups.
Avro Schemas

A script to purge the private label cache exists, though it does not appear to be used.
Private labeling is no longer used in the CP.
Click Tracking
The Click tracking component caches tracking url lookups in AppDB.
Throttling
The Throttler component uses cache keys with a TTL to rate-limit various actions in the CP including logins. An older Throttle component also exists with references to redcache, but appears unused.
Verify-Optin Processing
The VO Processor component uses the aweber_app_db_down cache key to determine
whether the control panel is under scheduled maintenance.
This component also resides separately in the Verify-Optin project, doing the same thing, and should be removed from the sites repository.
Unsubscribe / Manage Subscriptions
The Manage Subscriptions page uses the aweber_app_db_down cache key to
determine whether the control panel is under scheduled maintenance.
This component also resides separately in the Unsubscribe project, doing the same thing, and should be removed from the sites repository.

The Refer a Friend component uses the refer_a_friend:access_token key to store
and verify an access token.

families using the template_directory_web_form_popular key.

account ID and $aServId is an integer list ID or false.
List Twitter Account
The Vendor Account List model clears the twitter account on a list using the key
format orm.list.by_id.$listId.twitter_account. It is unclear what sets that
key.
One-Click Unsubscribe
The One-click remove handler uses the aweber_app_db_down cache key to
determine whether the control panel is under scheduled maintenance.

The Web form chicklet image handler caches image data stored in AppDB using the
key format aweber_app_chicklet_$id where $id is the integer ID of the
chicklet image.

The Template Gallery view helper caches email templates from the Template
Directory Service using the template_directory_{$type}_family_data key format,
where $type is web_form or block.

flagging.
Message Templates
The Message Templates controller clears the key

Feed Broadcasts
The Feed Broadcasts controller tracks feed gearman job status by setting and
retrieving the redis key patterns aweber_app_process_feed_{$sid}_complete and
aweber_app_process_feed_{$sid}_status, where $sid is the current session ID.

aweber_app_{$namespace}_remove_options_{$list_id}, where $namespace is the
value retrieved from the key aweber_app_remove_options_namespace.
Login Email Verification

login_email:verification_token:{$user['id']}
Sift Login Verification
The Account controller stores a flag allowing previously verified logins to
bypass the Sift score check using the key pattern
login_verification:verified_bypass:{$login}:{$ipAddress}.
Application maintenance
The App controller uses the aweber_app_db_down cache key to determine whether
the control panel is under scheduled maintenance.
Web Form Generation
The Web Form Generator component stores and retrieves web form settings using the key pattern {$namespace}_web_form_{$webFormId}{$type} where $namespace is the value retrieved from the key aweber_app_web_form_namespace, and type is one of the following:
