摘要:
Embodiments of the present invention include a computer-implemented systems and methods for accessing metadata across a network. A metadata server receives requests to access a data source from one or more clients. The metadata server is coupled between one or more backend servers and the clients. The backend servers may be coupled to the data sources of interest. The metadata server provides a metadata service proxy for establishing communications with the backend servers and for signaling the backend servers to establish connections to data sources. Data sources may be stateful or stateless. For stateless data sources, the metadata server may dynamically create reusable metadata service provider proxies that receive metadata from metadata service providers on the backend servers. For stateful data sources, unique metadata service provider proxies may be dynamically created and used to service client requests.

摘要:
A method and system of retrying to load data from a data source to a cloud target system are disclosed. A client device sends a data packet to a cloud server via a communication connection. The data packet comprises data. The client device receives an indication of a failure in the communication connection. The client device configures, in response to receiving the indication of the failure in the communication connection, the data packet to prompt the cloud server to perform an upsert operation with the data in the data packet. The client device sends the configured data packet to the cloud server. The client device can wait a predetermined amount of time before sending the configured data packet to the cloud server.
