--------------------------------------
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.
