Examples of PartitionAccessor

com.linkedin.d2.balancer.util.partitions.PartitionAccessor
This is the accessor for partition properties. It is here because we want to keep partition properties as data storage only and move the logic of manipulating the data to a separate place. To get a PartitionAccessor, one should use {@link PartitionAccessorFactory}

Examples of com.linkedin.d2.balancer.util.partitions.PartitionAccessor

    //get the partitionId -> host URIs list
    Map<Integer, List<URI>> hostList = new HashMap<Integer, List<URI>>();
    if (! orderedStrategies.isEmpty())
    {
      final LoadBalancerState.SchemeStrategyPair pair = orderedStrategies.get(0);
      final PartitionAccessor accessor = getPartitionAccessor(serviceName, clusterName);
      maxPartitionId = accessor.getMaxPartitionId();
      int hash = hashProvider.nextHash();
      for (int partitionId = 0; partitionId <= maxPartitionId; partitionId++)
      {
        Set<URI> possibleUris = uris.getUriBySchemeAndPartition(pair.getScheme(), partitionId);
        List<TrackerClient> trackerClients = getPotentialClients(serviceName, service, possibleUris);

      //this function may fail. The reason why we don't check whether the strategy support partitioning
      //is because the downstream code will check it for us and the user will be notified about
      //this problem. Plus it doesn't make sense for a user to have partitioning but didn't specify a
      //strategy that supports partitioning
      final LoadBalancerState.SchemeStrategyPair pair = orderedStrategies.get(0);
      final PartitionAccessor accessor = getPartitionAccessor(serviceName, clusterName);


      //get the partitionId -> keys mapping
      Map<Integer, Set<K>> partitionSet = new TreeMap<Integer, Set<K>>();
      for (final K key : keys)
      {
        int partitionId;
        try
        {
          partitionId = accessor.getPartitionId(key.toString());
        }
        catch (PartitionAccessException e)
        {
          unmappedKeys.add(key);
          continue;
