Discussion Topics

• Demo Solr port of OpenSearch Benchmark tool + discuss performance benchmarking follow up (Kevin / Jan)
  • https://github.com/janhoy/solr-benchmark
  • David pointed out naming conflict with solr/benchmark. Should it have "rally" in the name since its a fork of it?
  • Solr Performance Benchmarking
  • How are data sets defined? How are queries defined?
  • Still requires a level of Solr integration, regardless of the tool

  • Slides -
  • Repo - https://github.com/parveensaini/solr-lucene-migration-correctness
  • Has this issue been seen by others during major version upgrades?
    • David mentioned Lucene changes from 7 to 8. Otherwise, things have generally been steady
    • Hoss called out smaller changes that could amount to bigger diffs
    • Luke mentioned changes to edismax parser in 9 (from 8?)

• Benchmarking: New "SolrBackend" – and WIP for adapting solr/benchmark to use it, will share a PR soon.  Similarly for SolrClientTestRule to use SolrBackend. (David)

  • Ran out of time. Decided that we should continue the benchmarking discussion asynchronously (mailing list, confluence page)
