Class TDigestHolder

java.lang.Object

org.elasticsearch.compute.data.TDigestHolder

public class TDigestHolder
extends Object

This exists to hold the values from a TDigestBlock. It is roughly parallel to TDigestState in classic aggregations, which we are not using directly because the serialization format is pretty bad for ESQL's use case (specifically, encoding the near-constant compression and merge strategy data inline as opposed to in a dedicated column isn't great).
