* Made a record for lazy formatted trace values and formatter to improve
  maintainability
* Added callback to format return value from connector
  * Extended test case to check that the format return value callback
    works
* Added handling of "lazy" trace entry data to the text formatter. Do we

emqx_resource

The emqx_resource is a behavior that manages configuration specs and runtime states for resources like mysql or redis backends.

It is intended to be used by the emqx_bridges and all other resources that need CRUD operations to their configs, and need to initialize the states when creating.

There can be foreign references between resource instances via resource-id. So they may find each other via this Id.

The main idea of the emqx resource is to put all the general code in a common lib, including the config operations (like config validation, config dump back to files), and the state management. And we put all the specific codes to the callback modules.

See

  • test/emqx_connector_demo.erl for a minimal emqx_resource implementation;
  • test/emqx_resource_SUITE.erl for examples of emqx_resource usage.
