[jira] [Commented] (NIFI-3262) PutElasticsearch support for _routing/_parent

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

    [ https://issues.apache.org/jira/browse/NIFI-3262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17618801#comment-17618801 ] 

Chris Sampson commented on NIFI-3262:
-------------------------------------

Think this would be a similar problem to NIFI-10067, e.g. we want to allow a configurable way of specifying the {{IndexOperation}} part of the {{_bulk}} API call for Records being sent to Elasticsearch.

> Due to the structure of the current nifi Elasticsearch indexing processors, it doesn't appear possible to specify explicit _routing or _parent fields when using any of the PutElasticsearch processors (PutElasticsearch, PutElasticsearchHTTP, PutElasticsearch5).
> The ability to optionally specify the _parent and/or _routing parameters that can be present in a normal bulk index request would be really valuable.
> An alternative to adding a handled attribute would be adding support for the bulk indexing syntax as defined on https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html - a two line structure where line one contains the indexing instructions in a JSON object, and line two contains the content of the object. Each line ends with an explicit newline character (\n). This would allow bulk indexing, update, delete, etc operations to be carried out through nifi.
