Overview
QA test script for validating dynamic batcher functionality in the Triton Inference Server.
Description
This test orchestrates comprehensive validation of the dynamic batcher subsystem. It exercises batching behavior across multiple dimensions including preferred batch sizes, max queue delay, priority-based scheduling, request queuing semantics, sequence batching interactions, and batch formation under varying load patterns. The script generates model configurations with different batching parameters, sends concurrent inference requests with controlled timing, and verifies that requests are batched according to the configured policies. It checks correct batch sizes in server logs, validates request latencies against queue delay settings, and ensures priority levels are respected during batch formation.
Usage
Run as part of the Triton QA test suite to validate dynamic batching. Typically executed in CI/CD pipelines within the Triton Docker container environment.
