- 10. • Subset of optional features in Solr to enable and simplify horizontal scaling a search index using sharding and replication • Goals: scalability, performance, high-availability, simplicity, and elasticity What is SolrCloud?
- 11. • ./bin/solr -e cloud • Yeah, it’s that simple! Running SolrCloud
- 12. SolrCloud demo
- 13. • http://wiki.apache.org/solr/HowToContribute • Pre-requisites: • git: git clone http://git-wip-us.apache.org/repos/asf/ lucene-solr.git • github: fork and clone apache/lucene-solr • ant 1.8.x or above • Eclipse or Intellij Idea (I recommend Idea) • Put svn/git and ant in your $PATH or %PATH% Hacking Solr
- 14. • ant ivy-bootstrap (required only once) • ant idea or ant eclipse (generated a complete project for you which you can open in your favourite IDE) • Find an existing Jira issue or open a new one at http:// issues.apache.org/jira/browse/SOLR • Make changes, write tests, once finished: • run ‘cd solr; ant server’ to build Solr and start via bin/solr scripts • run ‘ant test’ (it can take a while), ensure all tests pass • run ‘ant precommit’, (run from the checkout root) ensure it passes • Generate a patch with ‘svn diff’ or ‘git diff’ and attach to Jira Hacking Solr
