Transport channel via web socket for OData

The present disclosure involves systems, software, and computer implemented methods for providing an asynchronous transport channel for OData data using web sockets. One example method includes upgrading a HTTP connection to a web socket connection in response to an upgrade request. The web socket connection is maintained, after the upgrading, for receipt of subsequent web socket requests. An OData request is received, from a consuming application, over the web socket connection. The OData request is translated to a format used by an OData runtime environment and sent to the OData runtime environment. A response to the OData request is received from the OData runtime environment. The response is incorporated into a web socket message. The web socket message is sent to the consuming application, over the web socket connection, in response to the OData request, with the web socket connection remaining open after the web socket message is sent.
