Caideyipi opened a new pull request, #18501: URL: https://github.com/apache/iotdb/pull/18501
### What changes were proposed in this pull request?\n\n- Fix the batch-accumulation condition so the dispatcher waits after buffering the first request when write pressure is low.\n- Make IoTConsensus configuration updates visible across dispatcher threads and propagate hot-reloaded limits to the existing dispatcher pipeline.\n- Update the IoTConsensus queue memory ratio on configuration reload.\n- Add unit coverage for batch accumulation, pipeline reload wake-up, and memory-ratio updates.\n\nThis is intentionally scoped to the lightweight, clearly incorrect paths; it does not claim to resolve every possible WAL/decompression performance issue.\n\n### Why are the changes needed?\n\nThe previous condition checked ufferedEntries.isEmpty() only after adding a request, so the accumulation wait was never reached. Existing dispatcher threads also retained stale reloadable limits.\n\n### How was this tested?\n\n- mvn -pl iotdb-core/consensus clean test (72 tests, 0 failures, 0 errors)\ n -- This is an automated message from the Apache Git Service.
