Configure maxParallelForks 4 in runners/google-cloud-dataflow-java/worker/build.gradle matching the convention used across Beam's core and runner modules.
…suites StreamingDataflowWorkerTest is 6,600+ lines and takes over 2 minutes sequentially on a single fork. Sharding into concrete Appliance and StreamingEngine test classes allows Gradle to execute them concurrently on separate forks.
Avoids 10-second idle socket keep-alive timeout in Jetty's LocalConnector across test methods, reducing suite execution from 40s to ~50ms.
Replace on-the-fly generation of 10GB random bytes via Random.nextBytes() in tight 1M loops with fast bit-shift integer indexing into the buffer, saving ~45s of CPU time.
- Reduce polling intervals from 100ms to 10ms while preserving total timeout ceilings. - Remove unnecessary 10s sleep in synchronous StreamingGlobalConfigHandleImplTest. - Advance StreamDebugMetricsTest via virtual clock without wall-clock sleep.
