------------------------------
Summary: Upgrading Elasticsearch version from 7.0.1 to 7.15 in
Elasticsearch Adapter
Key: CALCITE-4898
URL: https://issues.apache.org/jira/browse/CALCITE-4898
Project: Calcite
Issue Type: Improvement
Components: elasticsearch-adapter
Affects Versions: 1.28.0
Reporter: ZheHu
Assignee: ZheHu
The current Elasticsearch version in Calcite is 7.0.1, while the latest
released ES version is 7.15.2.
There are many new SQL features added and bugs fixed from 7.0.1 to 7.15. By
upgrading the embedded ES, we can make good use of ES's new features,
especially about DSL, which enable developers to find one more suitable or
effective way to implement features and improve existing functions.
Since series of 7.x versions have good compatibility, this issue will just
upgrade ES server without adjusting RestClient version in Elasticsearch Adapter.
