View solution

Q. Terracotta is different than most clustered caches today because it has no visible API

View solution

Q. Terracotta has a client/server architecture.

Q. To use the script on Unix-like operating systems:

View solution

Q. To distribute processing over many nodes, perhaps to increase result speed through the use of concurrences, perhaps merely to provide load balance and fault tolerance.

Q. There are many data grids, such as :-

View solution

Q. Map/reduce is a pattern that was popularized by Google, and it comes from functional programming languages, which often have:-

View solution

Q. To quickly grid-enable a method on a bean using GridGain.

View solution

Q. GridGain provides:-

View solution

Q. To build a parallelized solution for a problem that’s intrinsically better-suited to parallelization or that, for want of resources, needs to be chunked.

View solution

Q. GridGain works with a GridTask, which specifies how to handle the main unit of work of the interface type:-

View solution

Q. When you call the method on the service with the @Gridify annotation pointing to this GridTask implementation, it stops execution of method and loads an instance of this implementation.

View solution

Q. When using GridGain stem mostly from the fact that what you develop on one node can’t always automatically work on another node with no additional configuration.

View solution

Q. GridGain lets you start up nodes using the startup script in the:-
