DomainDiscoveryStrategy (Payara Project 6.2025.7 API)

java.lang.Object
- com.hazelcast.spi.discovery.AbstractDiscoveryStrategy
- - fish.payara.nucleus.hazelcast.DomainDiscoveryStrategy

All Implemented Interfaces:

com.hazelcast.spi.discovery.DiscoveryStrategy
```
public final class DomainDiscoveryStrategy
extends com.hazelcast.spi.discovery.AbstractDiscoveryStrategy
```
Delegate to the Domain Discovery Service for node discovery.
Separate different domain instance groups into partition groups, and optionally implements host-aware partitioning since it's not possible to combine Hazelcast's (very) simple implementation of host-aware partitioning and custom API-based discovery strategy
