-# emqx_connector
-
-This application is a collection of `connectors`.
-
-A `connector` is a callback module of `emqx_resource` that maintains the data related to
-external resources. Put all resource related callback modules in a single application is good as
-we can put some util functions/modules here for reusing purpose.
-
-For example, a mysql connector is an emqx resource that maintains all the mysql connection
-related parameters (configs) and the TCP connections to the mysql server.
-
-An mysql connector can be used as following:
-
-```
-(emqx@127.0.0.1)5> emqx_resource:list_instances_verbose().
-[#{config =>
-       #{auto_reconnect => true,cacertfile => [],certfile => [],
-         database => "mqtt",keyfile => [],password => "public",
-         pool_size => 1,
-         server => {{127,0,0,1},3306},
-         ssl => false,user => "root",verify => false},
-   id => <<"mysql-abc">>,mod => emqx_connector_mysql,
-   state => #{poolname => 'mysql-abc'},
-   status => started}]
-(emqx@127.0.0.1)6> emqx_resource:query(<<"mysql-abc">>, {sql, <<"SELECT count(1)">>}).
-{ok,[<<"count(1)">>],[[1]]}
