Enum Constant Detail

SHUFFLE_MEMBER_LIST

public static final ClientProperty SHUFFLE_MEMBER_LIST

Client shuffles the given member list to prevent all clients to connect to the same node when this property is set to false. When it is set to true, the client tries to connect to the nodes in the given order.

HEARTBEAT_TIMEOUT

public static final ClientProperty HEARTBEAT_TIMEOUT

Client sends heartbeat messages to the members and this is the timeout for this sending operations. If there is not any message passing between the client and member within the given time via this property in milliseconds, the connection will be closed.

HEARTBEAT_INTERVAL

public static final ClientProperty HEARTBEAT_INTERVAL

Time interval between the heartbeats sent by the client to the nodes.

EVENT_THREAD_COUNT

public static final ClientProperty EVENT_THREAD_COUNT

Number of the threads to handle the incoming event packets.

EVENT_QUEUE_CAPACITY

public static final ClientProperty EVENT_QUEUE_CAPACITY

Capacity of the executor that handles the incoming event packets.

INVOCATION_TIMEOUT_SECONDS

public static final ClientProperty INVOCATION_TIMEOUT_SECONDS

Time to give up on invocation when a member in the member list is not reachable.

MAX_CONCURRENT_INVOCATIONS

public static final ClientProperty MAX_CONCURRENT_INVOCATIONS

The maximum number of concurrent invocations allowed.

To prevent the system from overloading, user can apply a constraint on the number of concurrent invocations. If the maximum number of concurrent invocations has been exceeded and a new invocation comes in, then hazelcast will throw HazelcastOverloadException

By default it is configured as Integer.MaxValue.

DISCOVERY_SPI_ENABLED

public static final ClientProperty DISCOVERY_SPI_ENABLED

Enables the Discovery SPI lookup over the old native implementations. This property is temporary and will eventually be removed when the experimental marker is removed.

Discovery SPI is disabled by default

DISCOVERY_SPI_PUBLIC_IP_ENABLED

public static final ClientProperty DISCOVERY_SPI_PUBLIC_IP_ENABLED

Enables the Discovery Joiner to use public ips from DiscoveredNode. This property is temporary and will eventually be removed when the experimental marker is removed.

Discovery SPI is disabled by default

INTERNAL_EXECUTOR_POOL_SIZE

public static final ClientProperty INTERNAL_EXECUTOR_POOL_SIZE

Configures pool size of internal client executor. Private configuration, for internal usage only.

Specified by:

clearSystemProperty in interface HazelcastProperty

Method Detail

values

public static ClientProperty[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

Returns:

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

valueOf

public static ClientProperty valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null
