ASF subversion and git services commented on SOLR-15694: -------------------------------------------------------- Commit 002b3ce67bea7dfe114c3b7dfdceb00b8777363c in lucene-solr's branch refs/heads/branch_8_11 from Ishan Chattopadhyaya [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=002b3ce67be ] Revert "SOLR-15694, 15715: Create ephemeral roles properly (missed backporting these changes last time)" This reverts commit b54a788fe71c7f87a8b8564461cb196c138fc7ce. > 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 > Fix For: 9.0 > > Time Spent: 7h 40m > Remaining Estimate: 0h > > 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 (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
