----------------------------------------
Summary: 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
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.
