Re: Stress Test Solr
Tomas, This seems like a really useful tool. We're holding a Solr/Lucene conference in Boston, 7-8 October 2010 - and this would be an interesting lightning talk subject. Let me know if you need more info on the event. - Mike Bohlig, Lucid Imagination - Original Message From: Tomas To: solr-user@lucene.apache.org Sent: Mon, August 2, 2010 8:33:46 AM Subject: Stress Test Solr Hi All, we've been building an open source tool for load tests on Solr Installations. Thetool is called SolrMeter. It's on google code at http://code.google.com/p/solrmeter/. Here is some information about it: SolrMeter is an stress testing / performance benchmarking tool for Apache Solr installations. It is licensed under ASL and developed using JavaSE and Swing components, connected with Solr using SolrJ. What can youdowith SolrMeter? The main goal of this open source project is bring to the Apache Solr user community a tool for dealing with Solr specific issues regarding performance and stress testing like firing queries and adding documents to make sure that your Solr instalation will support real world's load and demands. With SolrMeter you can simulate a work load over the Apache Solr instalation and to obtain useful visual performance statistics and metrics. Relevant Features: * Execute queries against a Solr installation * Execute dummy updates/inserts to the Solr installation, it can be the same server as the queries or a different one. * Configure number of queries to fire in a time period interval * Configure the number of updates/inserts in a time period. * Configure commits frequency during adds * Monitor error counts when adding and commiting documents. * Perform and monitor index optimization * Monitor query times online and visually * Add filter queries into the test queries * Add facet abilities into the test queries * Import/Export test configuration * Query time execution histogram chart * Query times distribution chart * Online error log and browsing capabilities * Individual query graphical log and statistics * and much more Whatdo you need for use SolrMeter? This is one of the most interesting points about SolrMeter, the requirements are minimal. It is simple to install and use. * JRE versión 1.6 * The Solr Server you want to test. Who can use SolrMeter? Everyone who needs to assess the solrmeter server performance. To run the tool you only need to know about SOLR. Try it and tell us what you think . . . . . Solrmeter Group mailto:solrme...@googlegroups.com What's next? We are now building version 0.2.0, the objetive of this new version is to evolve SolrMeter into a pluggable architecture to allow deeper customizations like adding custom statistics, extractors or executors. We are also adding some usability improvements. On future versions we want to add a better interaction with Solr request handlers, for example, showing cache statistics online and graphically on some chart would be a great tool. We also want to add more usability features to make of solrmeter a complete tool for testing a Solr instalation. For more details on what's next che the Issues page on the google code site.
Re: Different between Lucid dist. & Apache dist. ?
Information about Lucid's Certified Distribution is at: http://www.lucidimagination.com/Downloads/LucidWorks-for-Lucene It's available at no cost and includes: * Complete version of Apache Lucene v3.0.1 * Additional bug fixes from the current trunk of the Lucene project * 30-day free Get Started assistance * LucidKStemmer: Lucid's optimized version of KStemmer, the Krovetz stemmer available from the University of Massachusetts. A stemmer reduces words to a root form, providing the ability to search for derivatives of a stem word (e.g., "team" is the stem of "teams"). This is a dictionary based inflectional stemmer that stems less aggressively than the standard Porter stemmer included with Apache Lucene. LucidKStemmer is English-only at this time. * Lucene Index Toolbox (Luke):-Mike - Original Message From: Floyd Wu To: solr-user@lucene.apache.org Sent: Mon, October 4, 2010 10:56:31 PM Subject: Different between Lucid dist. & Apache dist. ? Hi there, What is the difference between Lucid distribution of Solr and Apache distribution? And can I use Lucid distribution for free in my commercial project?
Re: Example Solr Config on EC2
Matthew, Here's another resource: http://www.lucidimagination.com/blog/2010/02/01/solr-shines-through-the-cloud-lucidworks-solr-on-ec2/ Michael Bohlig Lucid Imagination - Original Message From: Matt Shields To: solr-user@lucene.apache.org Sent: Mon, August 8, 2011 2:03:20 PM Subject: Example Solr Config on EC2 I'm looking for some examples of how to setup Solr on EC2. The configuration I'm looking for would have multiple nodes for redundancy. I've tested in-house with a single master and slave with replication running in Tomcat on Windows Server 2003, but even if I have multiple slaves the single master is a single point of failure. Any suggestions or example configurations? The project I'm working on is a .NET setup, so ideally I'd like to keep this search cluster on Windows Server, even though I prefer Linux.
