July 2025 Monthly Summary: Implemented a new EDW Search Index Benchmarking feature for PerfKitBenchmarker to measure search index creation, coverage, and verification across EDW services (BigQuery and Snowflake). The feature includes SQL scripts to create, check coverage, and delete search indexes, plus a Python orchestrator, and extends the benchmark timeout to accommodate longer index-building times. This work enhances cross-cloud benchmarking capabilities and provides a foundation for data-driven performance optimization of EDW search indexing.
