Data Transfer Agent Library
- Description: The CL for the Data Transfer Agent operations
- Type: Java
- Protocol: Local
- Framework: CL
- Key Features:
- synchronous/asynchronous transfers over data transfer service operations
- transfer monitoring
- transfer outcomes to clients
Data Transfer Agent Service
- Description: Structured/Unstructured transfer operations among data Source/Storages
- Type: gCube Web Service
- Protocol: SOAP
- Framework: gCore
- Key Features:
- transfer of local files from an external/internal client to a remote GHN
- file transfer from a remote Data Source to a remote GHN using standard protocols ( HTTP, FTP, BitTorrent)
- file transfer from a remote Data Source to the gCube Storage Manager ( MongoDB) using standard protocols ( HTTP, FTP, BitTorrent)
- tree based data transfer from a remote Data Source to a remote tree-based data storage
- transfer statistics publication trough messaging
gRS2 Broker
- Description: This component exposes the gCube Resultset as an http endpoint
- Type: Java Servlet
- Protocol: REST
- Framework: HTTP Front End
- Key Features:
- results are exposed as an HTTP endpoint
- results are in XML format
- server response is compressed in order to achieve performance benefits
- the records are retrieved iteratively - gradually
- number of results can be customized (max parameter)
- files are stored locally on the server (garbage collection)
