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

    [ https://issues.apache.org/jira/browse/OAK-2887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14550602#comment-14550602 ] 

Chetan Mehrotra commented on OAK-2887:
--------------------------------------

[~catholicon] Whats required is to just generate the mongoexport command. As at time the documents become quite big and cause the mongo shell to crash. mongoexport can easily handle such big documents. So we need to provide a function to dump that export command and then user can copy that command and execute it directly

> At time to analyse a issue with {{DocumentNodeStore}} running on Mongo we need a dump of various documents so as to recreate the scenario locally. In most case if issue is being observed for a specific path like /a/b then its sufficient to get Mongo documents for /, /a, /a/b and all the split documents for those paths.
> It would be useful to have a function in oak-mongo which generates the required export command. For e.g. for path like /a/b following export command would dump all required info

> mongoexport -h <mongo server> --port 27017 --db <db name> --collection nodes --out all-required-nodes.json --query '{$or:[{_id : /^4:p\/a\/b\//},{_id : /^3:p\/a\//},{_id : /^2:p\//},{_id:{$in:["2:/a/b","1:/a","0:/"]}}]}'
> {noformat}
