Subject [jira] Commented: (SOLR-1708) Allowing import / update of a specific document using the data import handler
Date Tue, 12 Jan 2010 12:38:54 GMT


Noble Paul commented on SOLR-1708:

This does not seem to be a good way to solve your problem. you can pass your root-pk as params
and use them in your queries directly


We cannot change the core of DIH for this kind of  problems

>                 URL:
>             Project: Solr
>          Issue Type: New Feature
>          Components: contrib - DataImportHandler
>    Affects Versions: 1.4
>            Reporter: Simon Lachinger

> There is the need that changes or new documents need to be added immediately to the Solr
Index. This could easily done via the update-handler - however, when using the DataImportHandler
it shouldn't be necessary to specify the data extraction for the the DataImportHandler and
also for feeding it to into the update-handler. It should be centralized.
> Having to run delta query, identifying the changes, for changes where the ID's of the
updated documents are already known to the application is a rather costly (in terms of database
load) way to solve this.
> The attached patch allows to specify one or more query parameters for the delta-import
command, named 'root-pk', which allow to specify the document(s) to be updated or added.
