From 18fc1bc0e0610a8ab1531629a9f6c96932a8f287 Mon Sep 17 00:00:00 2001 From: Andrew Kryczka Date: Wed, 8 Mar 2017 17:43:11 -0800 Subject: [PATCH] minor changes for rate limiter test flakiness Summary: the 50%+ drained constraint wasn't working consistently in some of our test environments, maybe their resources are too low. relax the constraints a bit.
