Interface IClientClusterGroup

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:

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");

Namespace: Apache.Ignite.Core.Client

Assembly: Apache.Ignite.Core.dll

Syntax

public interface IClientClusterGroup

Methods

ForAttribute(String, String)

Creates projection for nodes containing given name and value specified in user attributes.

Declaration

IClientClusterGroup ForAttribute(string name, string val)

Parameters

Type	Name	Description
System.String	name	Name of the attribute.
System.String	val	Optional attribute value to match.

Returns

Type	Description
IClientClusterGroup	Grid projection for nodes containing specified attribute.

ForDotNet()

Creates grid projection for nodes supporting .NET, i.e. for nodes started with Apache.Ignite.exe.

Declaration

IClientClusterGroup ForDotNet()

Returns

Type	Description
IClientClusterGroup	Grid projection for nodes supporting .NET.

ForPredicate(Func<IClientClusterNode, Boolean>)

Creates a grid projection which includes all nodes that pass the given predicate filter.

Declaration

IClientClusterGroup ForPredicate(Func<IClientClusterNode, bool> p)

Parameters

Type	Name	Description
System.Func<IClientClusterNode, System.Boolean>	p	Predicate filter for nodes to include into this projection.

Returns

Type	Description
IClientClusterGroup	Grid projection for nodes that passed the predicate filter.

ForServers()

Creates a cluster group of nodes started in server mode (ClientMode).

Declaration

IClientClusterGroup ForServers()

Returns

Type	Description
IClientClusterGroup	Cluster group of nodes started in server mode.

GetCompute()

Gets compute functionality over this grid projection. All operations on the returned compute instance will only include nodes from this projection.

Declaration

IComputeClient GetCompute()

Returns

Type	Description
IComputeClient	Compute instance over this grid projection.

GetNode()

Gets first node from the list of nodes in this projection.

Declaration

IClientClusterNode GetNode()

Returns

Type	Description
IClientClusterNode	Node.

GetNode(Guid)

Gets a node for given ID from this grid projection.

Declaration

IClientClusterNode GetNode(Guid id)

Parameters

Type	Name	Description
System.Guid	id	Node ID.

Returns

Type	Description
IClientClusterNode	Node with given ID from this projection or null if such node does not exist in this projection.

GetNodes()

Gets read-only collections of nodes in this projection.

Declaration

ICollection<IClientClusterNode> GetNodes()

Returns

Type	Description
System.Collections.Generic.ICollection<IClientClusterNode>	All nodes in this projection.

GetServices()

Gets services functionality over this grid projection. All operations on the returned services instance will only include nodes from this projection.

Declaration

IServicesClient GetServices()

Returns

Type	Description
IServicesClient	Services instance over this grid projection.
