[jira] [Resolved] (SOLR-8675) Accessing a field in custom request
handler is very slow
[ https://issues.apache.org/jira/browse/SOLR-8675?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erick Erickson resolved SOLR-8675.
----------------------------------
Resolution: Not A Problem
Please raise issues like this on the user's list, we try to keep JIRA for issues in the code base, not custom code questions.
In this case, I'm assuming your code is in a collect method or some such. You're going out to disk and decompressing at least 16K for each doc. This is an anti-pattern as stated in the docs.
One possibility would be to access the indexed term directly, or perhaps create it as a DocValues field and access that.
Please ask for further details on the user's list.

> Key: SOLR-8675
> URL: https://issues.apache.org/jira/browse/SOLR-8675
> Project: Solr
> Issue Type: Improvement
> Components: search, SearchComponents - other
> Affects Versions: 4.3.1
> Reporter: Neeraj Lajpal
>
> I am trying to access a field in custom request handler. I am accessing it like this for each document:
> Document doc;
> doc = reader.document(id);
> DocFields = doc.getValues("state");
> There are around 600,000 documents in the solr. For a query running on all the docs, it is taking more than 65 seconds.
> I have also tried SolrIndexSearcher.doc method, but it is also taking around 60 seconds.
> Removing the above lines of code bring down the qtime to milliseconds. But, I need to access that field for my algo.
> Is there a more optimised way to do this?
