public IdGenerator getIdGenerator(String name)
HazelcastInstance
long
primitive values
between 0 and Long.MAX_VALUE. ID generation occurs almost at the speed of
local AtomicLong.incrementAndGet(). Generated IDs are unique during the life
cycle of the cluster. If the entire cluster is restarted, IDs start from 0 again.getIdGenerator

public FlakeIdGenerator getFlakeIdGenerator(String name)
HazelcastInstance
long
primitive values
and are k-ordered (roughly ordered). IDs are in the range from 0
to Long.MAX_VALUE
.
The IDs contain timestamp component and a node ID component, which is assigned when the member
joins the cluster. This allows the IDs to be ordered and unique without any coordination between
members, which makes the generator safe even in split-brain scenario (for caveats,
see here
).
For more details and caveats, see class documentation for FlakeIdGenerator
.
Note: this implementation doesn't share namespace with HazelcastInstance.getIdGenerator(String)
.
That is, getIdGenerator("a")
is distinct from getFlakeIdGenerator("a")
.

public QuorumService getQuorumService()
HazelcastInstance
Quorum service can be used to retrieve quorum callbacks which let you to notify quorum results of your own to the cluster quorum service. IMPORTANT: The term "quorum" simply refers to the count of members in the cluster required for an operation to succeed. It does NOT refer to an implementation of Paxos or Raft protocols as used in many NoSQL and distributed systems. The mechanism it provides in Hazelcast protects the user in case the number of nodes in a cluster drops below the specified one.
