We are publishing ClickBench benchmark results for KalDB against OpenSearch using the KalDB vs OpenSearch comparison harness and its cold/hot protocol. The run covers all 43 ClickBench query slots, includes two repetitions, completes without failures, and shows KalDB faster on a majority of the weighted query scores.

The current version of KalDB is pinned to OpenSearch 2.11.1, so the raw numbers in this post use OpenSearch 2.11.1 as the comparison target.
