public class PartitionGroupConfig extends Object
PartitionGroupConfig.MemberGroupType
: PER_MEMBER, HOST_AWARE
and CUSTOM.
In all cases a partition will never be created on the same group. If there are more partitions defined than
there are partition groups, then only those partitions, up to the number of partition groups, will be created.
For example, if you define 2 backups, then with the primary, that makes 3. If you have only two partition groups
only two will be created.
<partition-group enabled="true" group-type="PER_MEMBER"/>
This provides good redundancy when Members are on separate hosts but not if multiple instances are being
run from the same host.
<partition-group enabled="true" group-type="HOST_AWARE"/>
CUSTOM
partition group as follows:
<partition-group enabled="true" group-type="CUSTOM">
<member-group>
<interface>10.10.1.*</interface>
</member-group>
<member-group>
<interface>10.10.2.*</interface>
</member-group>
</partition-group>
The interfaces can be configured with wildcards ('*') and also with address ranges e.g. '10-20'. Each member-group
can have an unlimited number of interfaces.
You can define as many member-group
s as you want. Hazelcast will always store backups in a different
member-group to the primary partition.
<partition-group enabled="true" group-type="CUSTOM">
<member-group>
<interface>10.10.1.1</interface>
<interface>10.10.1.2</interface>
</member-group>
<member-group>
<interface>10.10.1.1</interface>
<interface>10.10.1.3</interface>
</member-group>
</partition-group>
In this example there are 2 groups, but because interface 10.10.1.1 is shared between the 2 groups, this member
may store store primary and backups.
