Method Detail

getShardSize

java.lang.Long getShardSize()

Returns how many terms the coordinating node will request from each shard. Once all the shards responded, the coordinating node will then reduce them to a final result which will be based on the size parameter - this way, one can increase the accuracy of the returned terms and avoid the overhead of streaming a big list of buckets back to the client.

Returns:

the number of terms the coordinating node will request from each shard.

accept

default void accept(AggregationVisitor visitor)

Specified by:

accept in interface Aggregation
