DIH -> how to collect added/error unique keys?

[Kai Gülzau]

Hi *,

I am using DataImportHandler to do imports on a INDEX_QUEUE table (UKEY | 
ACTION)
using a custom Transformer which adds fields from various sources depending on 
the UKEY.

Indexing works fine this way.

But now I want to delete the rows from INDEX_QUEUE which were successfully 
updated.

-> Is there a good "API way" to do this?

Right now I'm using custom RequestProcessor which collects the UIDs and calls a 
method
on a singleton with access to the DB. It works but I hate these global 
singletons... :-(

public void processAdd(AddUpdateCommand cmd) throws IOException {
      SolrInputDocument doc = cmd.getSolrInputDocument();
      try {
        super.processAdd(cmd);
        addOK(doc);
      } catch (IOException e) {
        addError(doc);
        throw e;
      } catch (RuntimeException e) {
        addError(doc);
        throw e;
      }
}

Any other suggestions?
