Through this example, you should have understood the bases : how to use parameters for an update processor, how to use and how works a custom update processor. You can now use the example update processor to develop your own.

If for any reason you have to maintain a previous version of your Update Processor, do not keep the jar in the same folder just by changing it's extension, for example "my_update_proc.jar.old". It will be class loaded as any jar by the Solr Server, no matter the extension. At run time the result will be unpredictable as the previous version of your classes can be used instead of the new one. |
