---------------------------------------
Summary: Support defining arbitrary autoscaling simulation
scenarios
Key: SOLR-13831
URL: https://issues.apache.org/jira/browse/SOLR-13831
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Andrzej Bialecki
Assignee: Andrzej Bialecki
In many cases where the {{bin/solr autoscaling}} tool is used it would be very
useful to be able to specify a concrete scenario to play out, eg:
* load a snapshot (or create a simulated cluster of N nodes)
* calculate suggestions
* apply suggestions
* kill one or more nodes
* loop N times
* make some arbitrary SolrRequest-s
* save snapshot
* etc...
This could be expressed as a very simple DSL that can be loaded from a text
file, with the following format:
{code:java}
# comments
// or comments
create_cluster numNodes=5 // inline comment
solr_request
/admin/collections?action=CREATE&name=testCollection&numShards=2&replicationFactor=2
loop_start iterations=10
calculate_suggestions
apply_suggestions
loop_end
save_snapshot path=/foo{code}
