[overlord-issues] [JBoss JIRA] (RTGOV-462) Explore whether ElasticSearch server can be embedded into container (EAP)

[ https://issues.jboss.org/browse/RTGOV-462?page=com.atlassian.jira.plugin.... ] ivan mckinley commented on RTGOV-462: ------------------------------------- 1) If we are starting a full server for production use, this would also require the full stack, wouldn't it? So this would be the same for both production and test/integration requirements? - correct. but perhaps in remote client mode there will be no need to pull in the full stack 2) Singleton - yes, although the ElasticsearchClient is not a singleton, it could manage a 'singleton' for the embedded server, in cases where the specific ElasticsearchClient instance has referenced it (or possibly where the host is unspecified). If the embedded node's config is obtained from the overlord-rtgov.properties, this should enable clustering to be supported/updated as appropriate, without impacting the individual components using ES. Unique config per instance - this could be more complex. It may be possible via the overlord-rtgov.properties when running in standalone mode, but (as I understand it) when we use domain mode, this info will be obtained from the xml - which will be common across a cluster of servers (I assume). So we may need the embedded nodes (in this scenario) to use a common general config, and potentially the more specific config is applied to ES nodes outside of EAP? - Domain mode. All ES nodes form a cluster based on config in xml(assumption). ES Configuration by default. Perhaps taking config from EAP clustering(if clustering in use). if another ES cluster or shard is required then a separate domain could be defined. what do you think? - Standalone. Flexible configuration using RTGov.properties. This is straight forward. -- This message was sent by Atlassian JIRA (v6.2.3#6260)
