From 56bf3e0b2cb9047b98e0ffd2b2800ad263ae04db Mon Sep 17 00:00:00 2001 From: Jen Hamon Date: Tue, 18 Nov 2025 02:35:09 -0500 Subject: [PATCH] Adopt orjson for JSON performance optimization - Add orjson>=3.0.0 dependency with loose version constraint - Replace json.dumps/json.loads with orjson throughout REST client code - Update both sync (urllib3) and async (aiohttp) code paths - Pre-serialize JSON for aiohttp requests for better performance - Update tests to handle orjson's compact JSON output - Add performance tests showing 4-23x improvements - All unit tests pass (316+ tests) Performance improvements: - Serialization: 14-23x faster for small payloads - Deserialization: 6-7x faster for small payloads - Similar improvements for larger payloads --- .gitignore | 1 +
