    Description

      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:

      # 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
