Type declaration

• leader: {
      imbalance: number;
      leaderDupl: number[];
      numberShards: number[];
      targetWeight: number[];
      totalShards: number;
      totalWeight: number;
      weightUsed: number[];
  }

  Information about the leader imbalance.

  • imbalance: number

    The measure of the total imbalance. A high value indicates a high imbalance.

  • leaderDupl: number[]

    The measure of the leader shard distribution. The higher the number, the worse the distribution.

  • numberShards: number[]

    The number of leader shards per DB-Server.

  • targetWeight: number[]

    The ideal weight of leader shards per DB-Server.

  • totalShards: number

    The sum of shards, counting leader shards only.

  • totalWeight: number

    The sum of all weights.

  • weightUsed: number[]

    The weight of leader shards per DB-Server. A leader has a weight of 1 by default but it is higher if collections can only be moved together because of distributeShardsLike.

• shards: {
      imbalance: number;
      numberShards: number[];
      sizeUsed: number[];
      targetSize: number[];
      totalShards: number;
      totalShardsFromSystemCollections: number;
      totalUsed: number;
  }

  Information about the shard imbalance.

  • imbalance: number

    The measure of the total imbalance. A high value indicates a high imbalance.

  • numberShards: number[]

    The number of leader and follower shards per DB-Server.

  • sizeUsed: number[]

    The size of shards per DB-Server.

  • targetSize: number[]

    The ideal size of shards per DB-Server.

  • totalShards: number

    The sum of shards, counting leader and follower shards.

  • totalShardsFromSystemCollections: number

    The sum of system collection shards, counting leader shards only.

  • totalUsed: number

    The sum of the sizes.
