api

DC DBsync API is Web Server Gateway Interface (WSGI) application to receive and process API calls, including keystonemiddleware to do the authentication, parameter check and validation. It receives API calls from DC Orchestrator to read/write/update resources in Databases on behalf of DC Orchestrator. The API calls are processed in synchronous way, so that the caller will wait for the response to come back.

Multiple DC DBsync API could run in parallel, and also can work in multi-worker mode.

Multiple DC DBsync API is designed and run in stateless mode.
