Employees from Griidgain Systems tutoriial company behind GridGain answer questions in a polite and helpful manner. Let’s write our first grid application which will count a number of non-white-space characters in a sentence.

Now lets play with some basic cache operations and see what happens: InputStreamReader ; import java.
Getting Started With GridGain Cloud: In-Memory Computing as a Service

Create the SQL schema using the statements below: Data APIs for Developers.
Also note how easily we brought our computations to the nodes where the data is cached, as opposed to bringing the data to the computations.
