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]]}
