Hello all,
I have integrated Solr into my project with success. I use a dataimporthandler
to first import the data mapping the fields to my schema.xml. I use Solrj to
query the data and also use faceting. Works great.
The question I have now is a general one on updating the index and how it
works. Right now, I have a thread which runs a couple of times a day to update
the index. My index is composed of about 20000 documents, and when this thread
is run it takes the data of the 20000 documents in the db, I create a
solrdocument for each and I then use this line of code to index the index.
SolrServer server = new
CommonsHttpSolrServer("http://localhost:8080/apache-solr-1.4.1/";);
Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
for (Iterator iterator = documents.iterator(); iterator.hasNext();) {
Document document = (Document) iterator.next();
SolrInputDocument solrDoc = SolrUtils.createDocsSolrDocument(document);
docs.add(solrDoc);
}
UpdateRequest req = new UpdateRequest();
req.setAction(UpdateRequest.ACTION.COMMIT, false, false);
req.add(docs);
UpdateResponse rsp = req.process(server);
server.optimize();
This process takes 19 seconds, which is 10 seconds faster than my older
solution using compass (another opensource search project we used). Is this the
best was to update the index? If I understand correctly, an update is actually
a delete in the index then an add. During the 19 seconds, will my index be
locked only on the document being updated or the whole index could be locked? I
am not in production yet with this solution, so I want to make sure my update
process makes sense. Thanks
Greg
