--------------------------------------

             Summary: Support pagination for buckets aggregations in ElasticSearch adapter
                 Key: CALCITE-2557
                 URL: https://issues.apache.org/jira/browse/CALCITE-2557
             Project: Calcite
          Issue Type: Bug
          Components: elasticsearch-adapter
            Reporter: Andrei Sereda
            Assignee: Julian Hyde


Elastic doesn't normally support pagination with aggregates (see 
 [4915|https://github.com/elastic/elasticsearch/issues/4915]).


 Starting with v6.1 there is [bucket aggregation sorting |https://www.elastic.co/guide/en/elasticsearch/reference/6.1/search-aggregations-pipeline-bucket-sort-aggregation.html] which can possibly be leveraged. However we have to support older versions of elastic like 2,5 and 6. Christian suggested to fetch larger dataset {{offset + limit}} and manually trim the result set on application side.
