Example 6 with ConsistentHashFactory

use of org.infinispan.distribution.ch.ConsistentHashFactory in project infinispan by infinispan.

the class TestClusterCacheStatus method conflictResolutionConsistentHash.

public static ConsistentHash conflictResolutionConsistentHash(TestClusterCacheStatus... caches) {
    ConsistentHashFactory chf = caches[0].joinInfo.getConsistentHashFactory();
    ConsistentHash hash = Stream.of(caches).map(TestClusterCacheStatus::readConsistentHash).reduce(chf::union).orElseThrow(IllegalStateException::new);
    return chf.union(hash, chf.rebalance(hash));
}

Example 7 with ConsistentHashFactory

use of org.infinispan.distribution.ch.ConsistentHashFactory in project infinispan by infinispan.

the class ClusterCacheStatus method calculateConflictHash.

@Override
public ConsistentHash calculateConflictHash(ConsistentHash preferredHash, Set<ConsistentHash> distinctHashes, List<Address> actualMembers) {
    // If we are required to resolveConflicts, then we utilise a union of all distinct CHs. This is necessary
    // to ensure that we read the entries associated with all possible read owners before the rebalance occurs
    ConsistentHashFactory chf = getJoinInfo().getConsistentHashFactory();
    ConsistentHash unionHash = distinctHashes.stream().reduce(preferredHash, chf::union);
    unionHash = chf.union(unionHash, chf.rebalance(unionHash));
    return chf.updateMembers(unionHash, actualMembers, capacityFactors);
