Ishan Chattopadhyaya commented on SOLR-15694: --------------------------------------------- Discussion is happening here: https://lists.apache.org/thread.html/rb3cbfddb6e3af9c671d037ce1e7341544a2f1ab287f184c8f53ac44c%40%3Cdev.solr.apache.org%3E > Concept of node roles and non-data nodes > ---------------------------------------- > > Key: SOLR-15694 > URL: https://issues.apache.org/jira/browse/SOLR-15694 > Project: Solr > Issue Type: New Feature > Components: AutoScaling > Reporter: Ishan Chattopadhyaya > Priority: Major > > I think we should have first class support for starting a Solr node in a mode > whereby no cores will be placed on them. These nodes are useful for certain > scenarios: > # Dedicated overseer nodes > # Nodes where only plugins are installed and used (e.g. cluster/node level > plugins) > # Dedicated nodes for querying (more on this to come later). > Today, to achieve this effect, one can: > 1. start a node (which will make it join live_nodes and be immediately > available for replica placement). > 2. Put replica placement rules or autoscaling policies to prevent replicas > from being placed there. This is not standardized, 8x has two ways to achieve > this (replica placement rules and autoscaling framework), 9x has a new > autoscaling framework. > Proposing a start parameter for starting a node that starts the node in this > configuration, and then internally this is handled appropriately (across 8x > and 9x). This should be Kubernetes/Docker friendly as well, since it is easy > to add an additional parameter for a startup (instead of putting things into > autoscaling.json in ZK via init scripts). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
