Create Carte Clusters

Overview

Explains how to set up Carte clusters.

You can set up Carte to operate as a standalone execution engine for a job or transformation. Within Spoon, you can define one or more Carte servers and send jobs and transformations to them on an individual basis. However, in some cases you will want to set up a cluster of Carte servers for work load distribution. You may also need to use several servers to improve performance on resource-intensive jobs or transformations. In these scenarios, you will establish a cluster of Carte servers. There are two paradigms for Carte clustering:

A static cluster is a Spoon instance managing Carte slave nodes that have been explicitly defined in the user interface.

A dynamic cluster is a single master Carte server with a variable number of available Carte slave node registered with it.

Static clusters are a good choice for smaller environments where you don't have a lot of machines (virtual or real) to use for PDI transformations. Dynamic clusters are more appropriate in environments where transformation performance is extremely important, or there can potentially be multiple concurrent transformation executions.
