[jira] [Commented] (OAK-3987) Indexer dry run mode

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-3987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092576#comment-16092576 ] 

Chetan Mehrotra commented on OAK-3987:
--------------------------------------

[~edivad] oak-run tool now supports out-of-band indexing where no changes are done to NodeStore [1]. This meets the dry run requirements.

If this looks fine to you then I would like to resolve this issue as done

> Based on a discussion on the dev list, it would be interesting to provide a {{dry run}} mode for the indexer which would give an indication of an average indexing time.
> Input could be:
> * path to index definition (mandatory)
> * path to the content (mandatory, default could be {{/}})
> * max number of nodes (optional, but I'd still cap this value so indexing doesn't take over the entire aem instance)
> Also, we could do this on a separate (dedicated) thread so it doesn't interfere with existing indexers.
