Subject [Solr Wiki] Trivial Update of "DataImportHandler" by OkkeKlein
Date Fri, 11 Nov 2011 12:36:36 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "DataImportHandler" page has been changed by OkkeKlein:
http://wiki.apache.org/solr/DataImportHandler?action=diff&rev1=298&rev2=299

  <<Anchor(commands)>> The handler exposes all its API as http requests . The
following are the possible operations
  
   * '''full-import''' : Full Import operation can be started by hitting the URL `http://<host>:<port>/solr/dataimport?command=full-import`
- 
    * This operation will be started in a new thread and the ''status'' attribute in the response
should be shown ''busy'' now.
    * The operation may take some time depending on size of dataset.
    * When full-import command is executed, it stores the start time of the operation in a
file located at ''conf/dataimport.properties''

     * '''commit''' : (default 'true'). Tells whether to commit after the operation.
     * '''optimize''' : (default 'true'). Tells whether to optimize after the operation.
     * '''debug''' : (default 'false'). Runs in debug mode. It is used by the interactive
development mode ([[#interactive|see here]]).
- 
      * Please note that in debug mode, documents are never committed automatically. If you
want to run debug mode and commit the results too, add 'commit=true' as a request parameter.
   * '''delta-import''' : For incremental imports and change detection run the command `http://<host>:<port>/solr/dataimport?command=delta-import`
. It supports the same clean, commit, optimize and debug parameters as full-import command.
   * '''status''' : To know the status of the current command, hit the URL `http://<host>:<port>/solr/dataimport`
. It gives an elaborate statistics on no. of docs created, deleted, queries run, rows fetched,
status etc.
