.. versionadded:: 2014.7.0
This is the default local master event queue built on sqlite. By default, an
sqlite3 database file is created in the `sqlite_queue_dir` which is found at::
/var/cache/salt/master/queues
It's possible to store the sqlite3 database files by setting `sqlite_queue_dir`
to another location::
sqlite_queue_dir: /home/myuser/salt/master/queues
