The OpenStack community infrastructure includes a modest ElasticSearch cluster indexing CI job results, behind the http://logstash.openstack.org/ and http://status.openstack.org/elastic-recheck/ services. We also use the CirrusSearch extension for Mediawiki (which relies on a local ElasticSearch instance) providing page searching for the https://wiki.openstack.org/ service. All of these run on virtual machine instances in Rackspace at the moment. > Are there any tuning recommendations ? Our use case isn't nearly as large as some, but you may be able to find some ideas in our Puppet module for ES and the customization class from which we instantiate it: https://git.openstack.org/cgit/openstack-infra/puppet-elasticsearch/tree/ https://git.openstack.org/cgit/openstack-infra/system-config/tree/modules/openstack_project/manifests/elasticsearch_node.pp -- Jeremy Stanley
