ASF subversion and git services commented on SOLR-11285: -------------------------------------------------------- Commit 11e208e4ce75f09b26e65b5630086084c192df09 in lucene-solr's branch refs/heads/branch_7x from [~ab] [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=11e208e ] SOLR-11285: Support simulations at scale in the autoscaling framework, part 1 (refactoring). > Support simulations at scale in the autoscaling framework > --------------------------------------------------------- > > Key: SOLR-11285 > URL: https://issues.apache.org/jira/browse/SOLR-11285 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Components: AutoScaling > Reporter: Andrzej Bialecki > Assignee: Andrzej Bialecki > Attachments: SOLR-11285.patch > > > This is a spike to investigate how difficult it would be to modify the > autoscaling framework so that it's possible to run simulated large-scale > experiments and test its dynamic behavior without actually spinning up a > large cluster. > Currently many components rely heavily on actual Solr, ZK and behavior of ZK > watches, or insist on making actual HTTP calls. Notable exception is the core > Policy framework where most of the ZK / Solr details are abstracted. > As the algorithms for autoscaling that we implement become more and more > complex the ability to effectively run multiple large simulations will be > crucial - it's very easy to unknowingly introduce catastrophic instabilities > that don't manifest themselves in regular unit tests. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
