You can use the Representational State Transfer (REST) gateway to access simple data grids that are hosted by a collective. This REST gateway is useful when you must access grid data from non-Java environments.
Transactions
Each REST operation to the WebSphere DataPower XC10 Appliance begins and ends an independent transaction to the data grid. It is not possible to chain together multiple operations into a single transaction.
Load balancing
When you are using the REST gateway, it is the client responsibility to load balance their requests onto the WebSphere DataPower XC10 Appliance collective. You can use an external load balancer or add additional logic in the HTTP client you are using in the client program.
Relationship to WebSphere eXtreme Scale REST data service
The REST gateway is a separate entity from the WebSphere eXtreme Scale REST data service, which implements the Microsoft ADO.NET Data Services interface.
