Sep 1, 2025Sep 2025: Delivered a configurable transaction isolation level for the Spanner oltp_read_write benchmark in PerfKitBenchmarker. By updating the sysbench configuration, users can specify RC, RR, or SER isolation levels, which are applied to Spanner connections to test different transaction behaviors. This enhancement increases benchmarking flexibility, accuracy, and reproducibility for Spanner workloads.
