comparator
- Specified by:
comparator
in classBucketOrder
- Returns:
- A comparator for the bucket based on the given aggregator. The comparator is used in two phases:
- aggregation phase, where each shard builds a list of buckets to be sent to the coordinating node. In this phase, the passed in aggregator will be the aggregator that aggregates the buckets on the shard level.
- reduce phase, where the coordinating node gathers all the buckets from all the shards and reduces them to a final bucket list. In this case, the passed in aggregator will be
null
