Example 16 with IntArray

use of org.h2.util.IntArray in project ignite by apache.

the class ReducePartitionMapper method stableDataNodesMap.

/**
 * @param topVer Topology version.
 * @param cctx Cache context.
 * @param parts Partitions.
 */
private Map<ClusterNode, IntArray> stableDataNodesMap(AffinityTopologyVersion topVer, final GridCacheContext<?, ?> cctx, @NotNull final int[] parts) {
    assert !cctx.isReplicated();
    List<List<ClusterNode>> assignment = cctx.affinity().assignment(topVer).assignment();
    Map<ClusterNode, IntArray> mapping = new HashMap<>();
    for (int part : parts) {
        List<ClusterNode> partNodes = assignment.get(part);
        if (!partNodes.isEmpty()) {
