From 711601e22acab4cf9ea89dad20fa60cc06ee0c1c Mon Sep 17 00:00:00 2001 From: Krish Dholakia Date: Wed, 30 Apr 2025 21:32:31 -0700 Subject: [PATCH] Add key-level multi-instance tpm/rpm/max parallel request limiting (#10458) * fix: initial commit of v2 parallel request limiter hook enables multi-instance rate limiting to work * fix: subsequent commit with additional refactors * fix(parallel_request_limiter_v2.py): cleanup initial call hook simplify it * fix(parallel_request_limiter_v2.py): working v2 parallel request limiter * fix: more updates - still not passing testing * fix(test_parallel_request_limiter_v2.py): update test + add conftest * fix: fix ruff checks * fix(parallel_request_limiter_v2.py): use pull via pattern method to load in keys instance wouldn't have seen yet Fixes issue where redis syncing was not pulling key until instance had seen it * test: update testing to cover tpm and rpm * fix(parallel_request_limiter_v2.py): fix ruff errors * fix(proxy/hooks/__init__.py): feature flag export * fix(proxy/hooks/__init_.py): fix linting error * ci(config.yml): add tests/enterprise to ci/cd * fix: fix ruff check * test: update testing --- .circleci/config.yml | 2 +- .pre-commit-config.yaml | 6 +- .../example_logging_api.py | 6 +- .../enterprise_hooks/blocked_user_list.py | 4 +- enterprise/enterprise_hooks/llm_guard.py | 10 +- .../parallel_request_limiter_v2.py | 384 ++++++++++++++++ .../enterprise_hooks/session_handler.py | 1 -
