[jira] [Commented] (FLINK-26088) Add Elasticsearch 8.0 support

["Martijn Visser (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-26088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17626471#comment-17626471 ] 

Martijn Visser commented on FLINK-26088:
----------------------------------------

For those who are wondering, why don't we just upgrade to a later version of the Elasticsearch REST High Level Java Client? That's because Elastic has changed the license to a non-Apache License compatible license since version 7.11. You can see the new license for version 7.17 at https://github.com/elastic/elasticsearch/blob/7.17/LICENSE.txt or check the licensing FAQ at https://www.elastic.co/pricing/faq/licensing

> Since Elasticsearch 8.0 is officially released, I think it's time to consider adding es8 connector support.
> The High Level REST Client we used for connection [is marked deprecated in es 7.15.0|https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high.html]. Maybe we can migrate to use the new [Java API Client|https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/8.0/index.html] at this time.
