Subject [jira] [Issue Comment Deleted] (NUTCH-2179) Cleanup job for SOLR Performance Boost
Date Tue, 01 Dec 2015 20:48:11 GMT

     [ https://issues.apache.org/jira/browse/NUTCH-2179?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Johnson updated NUTCH-2179:
---------------------------------
    Comment: was deleted

(was: Correct, it should be, but is currently writing them singleton.

I'm proposing we swap the current delete function

public void delete(String key) throws IOException {
    if (delete) {
      try {
        solr.deleteById(key);  //singleton delete
        numDeletes++;
      } catch (final SolrServerException e) {
        throw makeIOException(e);
      }
    }
  }

with

public void delete(String key) throws IOException {
		if (delete) {
			deleteURLs.add(key);
			if (inputDocs.size() + deleteURLs.size() >= batchSize) {
				sendRequest();
			}
		}
	}


and abstract the actual send request with a function that can be called from write, delete
and close.

I have a patch prepared, but I cannot get the branch to commit - I'll attempt again later.)
