| <div class="markdown level0 summary"><p>Defines grid projection which represents a common functionality over a group of nodes. |
| Grid projection allows to group Ignite nodes into various subgroups to perform distributed |
| operations on them. All ForXXX(...)' methods will create a child grid projection |
| from existing projection. If you create a new projection from current one, then the resulting |
| projection will include a subset of nodes from current projection. The following code snippet |
| shows how to create grid projections:</p> |
| <pre><code>var g = Ignition.StartClient().GetCluster(); |
| |
| // Projection over .NET nodes. |
| var remoteNodes = g.ForDotNet(); |
| |
| // Projection over server nodes. |
| var randomNode = g.ForServers(); |
| |
| // Projection over all nodes that have user attribute "group" set to value "worker". |
| var workerNodes = g.ForAttribute("group", "worker");</code></pre> |
