[jira] [Commented] (NIFI-8003) Create Elasticsearch update_by_query processor

["Chris Sampson (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-8003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17240270#comment-17240270 ] 

Chris Sampson commented on NIFI-8003:
-------------------------------------

Suggest this is achieved by refactoring the bulk of the existing {{DeleteByQueryElasticsearch}} processor into an abstract class, which can be extended by a new {{UpdateByQueryElasticsearch}} processor too - the same for the associated test class(es). A new {{updateByQuery}} method will be required in the {{ElasticSearchClientService}}, but again that will be very similar to the existing {{deleteByQuery}} method.

As I'm looking to implement NIFI-8001 already, it would probably make sense to do this at the same time because it's relatively straight forward and would be changing several of the same classes (and would therefore only cause merge issues later).
