Jim Ferenczi 2acafd4b15 Optimize composite aggregation based on index sorting (#48399) (#50272) ... Co-authored-by: Daniel Huang <danielhuang@tencent.com> This is a spinoff of #48130 that generalizes the proposal to allow early termination with the composite aggregation when leading sources match a prefix or the entire index sort specification. In such case the composite aggregation can use the index sort natural order to early terminate the collection when it reaches a composite key that is greater than the bottom of the queue. The optimization is also applicable when a query other than match_all is provided. However the optimization is deactivated for sources that match the index sort in the following cases: * Multi-valued source, in such case early termination is not possible. * missing_bucket is set to true		2019-12-20 12:32:37 +01:00
