Investigate Apache Solr benchmark

[farquet]

The Apache Solr project is a search platform written in Java. This looks like a good candidate for a renaissance benchmark.

Especially since they have JMH benchmarks that could be reused: https://github.com/apache/solr/tree/main/solr/benchmark

In this page, they mention:

Many Solr JMH benchmarks are actually closer to a full integration benchmark in that they run a single action against a full Solr mini cluster.

See org.apache.solr.bench.index.CloudIndexing for an example of this.

Here is the given benchmark: https://github.com/apache/solr/blob/main/solr/benchmark/src/java/org/apache/solr/bench/index/CloudIndexing.java
