[I] Support benchmarking of Solr streaming expressions [solr-orbit]
janhoy opened a new issue, #13:
URL: https://github.com/apache/solr-orbit/issues/13
## Summary
Solr [Streaming Expressions](https://solr.apache.org/guide/solr/latest/query-guide/streaming-expressions.html)
are a powerful distributed computation API, but Solr Orbit has no dedicated support for
benchmarking them. This issue tracks adding first-class streaming expression support.
## Motivation
- Streaming expressions cover aggregation, faceting, parallel SQL, graph traversal, and
machine learning scoring — workloads that differ significantly from standard query
benchmarks
- Teams running Solr for analytics or ETL pipelines need a way to compare expression
performance across Solr versions or cluster configurations
## Proposed scope
1. **New operation type:** `streaming-expression` in workload definitions, analogous to
the existing `query` and `bulk-index` operations
2. **Dedicated driver:** Execute expressions via `/stream` endpoint, collect timing and
tuple-count metrics
3. **Telemetry:** Capture rows-returned, execution-time, and error rate per expression
4. **Sample workload:** Add an example workload in `benchmarks/` that exercises common
streaming patterns (search, facet, rollup, jdbc-like aggregation)

I'm not certain how much we need in this repo and how much is needed in a future streaming expr workload (operation type). But I believe we need some code here to know how to send streaming expr to solr...
