Enum Constant Details

ZONE_AWARE

public static final MemberGroupStrategy ZONE_AWARE

Zone aware member group strategy.

This strategy will create a member group for each unique zone in the cluster.

RACK_AWARE

public static final MemberGroupStrategy RACK_AWARE

Rack aware member group strategy.

This strategy will create a member group for each unique rack in the cluster.

HOST_AWARE

public static final MemberGroupStrategy HOST_AWARE

Host aware member group strategy.

This strategy will create a member group for each unique host in the cluster.

NODE_AWARE

public static final MemberGroupStrategy NODE_AWARE

Node aware member group strategy (the default).

This strategy will create a member group for each node in the cluster, effectively behaving the same as if no member groups were defined.

Method Details

values

public static MemberGroupStrategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static MemberGroupStrategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

groupNodes

protected Collection<MemberGroup> groupNodes(Collection<Member> members,
 Function<Member,String> keyFunction)

Groups nodes by the given key function.

Parameters:

members - the nodes to group

keyFunction - the key function to apply to nodes to extract a key

Returns:

a collection of node member groups
