[jira] [Created] (CALCITE-2376) migrate elastic adapters to
(low-level) rest client
Andrei Sereda created CALCITE-2376:
--------------------------------------
Summary: migrate elastic adapters to (low-level) rest client
Key: CALCITE-2376
URL: https://issues.apache.org/jira/browse/CALCITE-2376
Project: Calcite
Issue Type: Improvement
Components: elasticsearch-adapter
Reporter: Andrei Sereda
Assignee: Julian Hyde
This is an effort to migrate existing Elastic Search adapters to use [low-level rest client|https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-low.html]. Existing [native transport client|https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.3/client.html] has been deprecated in 7.0 (to be removed in 8.x).
Another advantage of low-level client is that it is compatible with any ES server version and has few (non-core) dependencies. Part of this improvement, both ES2 and ES5 adapters will be unified and reside under new maven module {{elasticsearch}} (contrary to separate {{elasticsearch2}} and {{elasticsearch5}}).
h3. Breaking changes
Using new {{artifactId}} and {{SchemaFactory}} implementation will force clients to change their configuration and dependencies. No other breaking changes are expected.
