Memory Usage and Hardware Requirements for Solr
November 8, 2012
The SearchHub community at SearchHub.org provides open resources for Lucene and Solr developers. LucidWorks has recently shifted their former DevZone resources to this new platform, but took archived content with them as well. A post from earlier this year, “Memory Comparisons Between Solr 3x and Trunk,” focuses on hardware requirements and memory comparisons between open source search options.
Erick Erickson, the author, writes:
“At Lucid, we often get asked ‘How much hardware do I need given X documents and Y QPS?’ A similar question is ‘How many documents can I fit on a machine like Z?’ These are perfectly reasonable questions, ones I’d like to have answered myself. Grant Ingersoll created a spreadsheet that tries to help estimate the memory requirements here: Grant’s Memory Estimator. Looking at that, you’ll see some of the problems. There are just too many variables you have to know up front. Often the hardware people are looking for some ballpark estimates before the search requirements are nailed down, which makes it even harder.”
While Lucene, Solr, or LucidWorks users can always find answers to their questions amongst the SearchHub content, researchers can also find interesting food for thought amongst the postings’ comments. Industry experts such as Paul Doscher, Otis Gospodnetic, and Charlie Hull often make appearances – proof that the LucidWorks offerings are built upon the trust names of open source industry standards Lucene and Solr.
