Extra info for Apache Solr 3.1 Cookbook

Sample text

We also set it so that the handler will be visible under /update/csv context; so, if your Solr is running on a local machine, the full URL would be like this: http://localhost:8983/solr/update/csv. We also told Solr to instantiate this update handler when it's used for the first time by adding the startup="lazy"parameter. Looking deeper into configuration, we have some additional parameters which define the behavior of the update handler. We tell Solr that the separator for the data will be the; character (separator parameter).

To send the example data to Solr, I used Ubuntu Linux and the curl command. First of all, I've added a new parameter to inform the update handler to perform commit after the data is read by adding the commit parameter set to true. You could ask why I didn't add it in the configuration. I could, but I want to control when my data will be committed. That's because I may have multiple CSV files which I don't want to be committed until the last of them is read; that's why I would add this parameter only with the last file I'm sending to Solr.

LRUCache. 4 version of Solr. So called FastLRUCache tends to be faster when Solr puts less into caches and gets more. This is the opposite to LRUCache that tends to be more efficient when there is more "puts" than "gets" operations. That's why we use it. This may be the first time you have seen cache configuration, so I'll explain what cache configuration parameters mean: ff class—you probably figured that out by now. Yes, this is the class implementing the cache ff size—this is the maximum size that the cache can have.
