From 39849627f7fa4e6a1ade12a8a33b62a3268f59dc Mon Sep 17 00:00:00 2001 From: Krish Dholakia Date: Sat, 31 May 2025 10:06:42 -0700 Subject: [PATCH] feat(parallel_request_limiter_v2.py): add sliding window logic (#11283) * feat(parallel_request_limiter_v2.py): add sliding window logic allows rate limiting to work across minutes * fix(parallel_request_limiter_v2.py): decrement usage on rate limit error * fix(base_routing_strategy.py): fix merge from redis - preserve values in in-memory cache during gap b/w push to redis and read from redis * fix(base_routing_strategy.py): catch the delta change during redis sync ensures values are kept in sync * fix(parallel_request_limiter_v2.py): update tpm tracking to use slot key logic * fix: fix linting error * test: update testing * test: update tests * test: skip on rate limit or internal server errors * test: use pytest fixture instead * test: bump mistral model --- .../hooks/parallel_request_limiter_v2.py | 115 +++++++++++-- litellm/proxy/proxy_server.py | 2 +- .../router_strategy/base_routing_strategy.py | 60 ++++--- tests/llm_translation/base_llm_unit_tests.py | 12 +- tests/llm_translation/test_cohere.py | 1 + tests/llm_translation/test_mistral_api.py | 2 +- .../hooks/test_parallel_request_limiter_v2.py | 156 ++++++++++++++---- .../test_base_routing_strategy.py | 52 ++++-- 8 files changed, 316 insertions(+), 84 deletions(-) diff --git a/litellm/proxy/hooks/parallel_request_limiter_v2.py b/litellm/proxy/hooks/parallel_request_limiter_v2.py index 8fbd8ad8f1..8ae192f5e3 100644 --- a/litellm/proxy/hooks/parallel_request_limiter_v2.py +++ b/litellm/proxy/hooks/parallel_request_limiter_v2.py @@ -132,42 +132,116 @@ class _PROXY_MaxParallelRequestsHandler_v2(BaseRoutingStrategy, CustomLogger): ): ## INCREMENT CURRENT USAGE increment_list: List[Tuple[str, int]] = [] + decrement_list: List[Tuple[str, int]] = [] + slots_to_check: List[str] = [] increment_value_by_group = { "request_count": 1, "tpm": 0, "rpm": 1, } -
