Introduction
The Akonadi framework is responsible for providing applications with a centralized database to store, index and retrieve the user's personal information. This includes the user's emails, contacts, calendars, events, journals, alarms, notes, etc. In SC 4.4, KAddressBook became the first application to start using the Akonadi framework. In SC 4.7, KMail, KOrganizer, KJots, etc. were updated to use Akonadi as well. In addition, several Plasma widgets also use Akonadi to store and retrieve calendar events, notes, etc.
At the time of writing, the following applications are enabled to use the Akonadi framework to centrally store and access user data. Follow through to each application's page to learn more.
KMail 
Mail Client Uses Akonadi to store emails
KAddressBook 
Contact Manager Uses Akonadi to store contact information
KOrganizer 
Personal Organizer Uses Akonadi to store calendars, events, journals, etc.
KJots 
Note Taking Application Uses Akonadi to store notes
In addition to this, plasma widgets like the Digital Clock widget, the Notes widget also use Akonadi to store and retrieve events and notes.
Controlling the Akonadi server
The Akonadi control module in System Settings provides an easy means to starting, stopping, restarting and querying the status of the Akonadi server. You may also accomplish this from the commandline using the command akonadictl.
To start the Akonadi server,
akonadictl start
To stop the Akonadi server,
akonadictl stop
To restart a running Akonadi server,
akonadictl restart
To query the status of the Akonadi server,
akonadictl status
Disabling the Akonadi subsystem
Shut down the Akonadi server from the control module or the command line:
akonadictl stop
Now, to disable autostarting the Akonadi server during login, edit the file ~/.config/akonadi/akonadiserverrc and change StartServer from true to false:
StartServer=false
The Akonadi server will no longer launch automatically.
Frequently Asked Questions
Refer to the Troubleshooting page for resolving glitches during migration. Akonadi's Glossary entry has a brief description of its purpose and other useful links. This page explains how Akonadi and KAddressBook work together.
If you are experiencing 100% CPU usage by the virtuoso-t process when using Akonadi and related applications, try this proposed workaround while it is being investigated: In KRunner's configuration page, disable the Nepomuk search plugin and the Contact plugin. Then, log out and back in. For further information and inputs, report back here or on the Forum or on the IRC channel #kontact.
