| <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.GetIgnite(); |
| |
| // Projection over remote nodes. |
| var remoteNodes = g.ForRemotes(); |
| |
| // Projection over random remote node. |
| var randomNode = g.ForRandom(); |
| |
| // Projection over all nodes with cache named "myCache" enabled. |
| var cacheNodes = g.ForCacheNodes("myCache"); |
| |
| // Projection over all nodes that have user attribute "group" set to value "worker". |
| var workerNodes = g.ForAttribute("group", "worker");</code></pre> |
| <p>Grid projection provides functionality for executing tasks and closures over |
| nodes in this projection using <a class="xref" href="Apache.Ignite.Core.Cluster.IClusterGroup.html#Apache_Ignite_Core_Cluster_IClusterGroup_GetCompute">GetCompute()</a>. |
| <p> |
| All members are thread-safe and may be used concurrently from multiple threads.</p> |
