## What is the purpose of the change This PR introduces an adaptive batch-sizing strategy for `JCQueue's` producer-side inserter, controlled by a new feature flag (`topology.producer.batch.dynamic`). Instead of committing to a fixed `producerBatchSz`, the new `DynamicBatchInserter` starts at a batch size of 1 and adjusts it online using AIMD: it additively grows the effective size (+1) after flushing a full batch (heavy load) and multiplicatively shrinks it (halving toward 1) after a timer-driven partial flush (light load), with the configured batch size acting as a ceiling rather than a fixed target. This lets the queue favor low latency under light load while preserving throughput under sustained back-pressure, without manual per-topology tuning. ## How was the change tested - Unit tests - Benchmark `BatchInserter` (baseline) vs `DynamicBatchInserter`, report in the first comment. -- This is an automated message from the Apache Git Service.
