Subject [jira] [Commented] (CONNECTORS-1009) Cmis Repository Connector does not handle Document updating properly
Date Fri, 15 Aug 2014 17:57:18 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098837#comment-14098837

Karl Wright commented on CONNECTORS-1009:
-----------------------------------------

Hi Prasad,

Please read this entry: https://chemistry.apache.org/java/0.9.0/maven/apidocs/org/apache/chemistry/opencmis/client/api/Session.html#query%28java.lang.String,%20boolean%29

Note that we call the session.query() method as follows:

{code}
      ItemIterable<QueryResult> results = session.query(cmisQuery, false).getPage(1000000000);
{code}

Note the "false" second argument, which if I read this right *should* cause the seed query
to return only the latest versions.  So, in theory, if you remove the document = document.getObjectOfLatestVersion()
invocation, the connector should work.

Please also note that you perform the full crawl equivalent of continuous crawling by just
setting up a a set of schedule windows, and making sure you turn off the requirement that
crawls only ever begin at the start of a window.

> As a part of the Fix for CONNECTORS-1004, It seems CmisRepositoryConnector does not handle
document updating properly.
> Case Scenario:
> * Create a continuous crawling job using  CmisRepositoryConnector.
> * Update a document on repository end.
> * The document keep submitting to OutputConnector at each crawling interval though it
was not updated afterwards.
> One possible Fix needed I is : @ CmisRepositoryConnector:processDocument,
>  activities.ingestDocumentWithException(nodeId, version, documentURI, rd);
> The documentURI should point to the old document URI (Now it points to the latest documentURI
discovered and it may seems to confuse document references ?)
> Also, In ECM systems, for example in Alfresco, the documentIDs are formulated with the
version number as well.
> Ex: workspace://SpacesStore/8e12a887-3fa8-48d6-8516-5bcfad358ba2;1.0 --> version 1.0
> workspace://SpacesStore/8e12a887-3fa8-48d6-8516-5bcfad358ba2;1.1 --> version 1.1
> When we setup a query to crawl a repository folder, we discover content by referring
the child nodes. Because of that, now it seems to queue all the document versions and submit
them to OutputConnector thus producing duplicate documents at the output (search) side.
> Is there a way to avoid this problem ? It will be great if the repository can just take
the latest document version and submit it as an update.
