SIG-Scheduling Deep Dive
summary
Overview of concrete scheduler changes and runnable tools: config now supports a multi-point extension so enabling plugins is just a name list (available in v1.23 v1beta3 and legacy configs still work); a schedulingGates field is in progress to hold pods out of the queue until controllers remove gates (target v1.26); PodTopologySpread adds minDomains and skew logic now can consider taints and nodeAffinity; performance fixes reduce prefilter work and memory churn. New tools include a simulator and Cork which can emulate thousands of nodes (5,000 shown) locally.
