From d603c40a21c80b87261f3eb6f4989b6c5f61feb7 Mon Sep 17 00:00:00 2001 From: Nathan VanBenschoten Date: Mon, 30 Sep 2024 16:40:05 -0400 Subject: [PATCH] kvserver: metamorphically enable kv.raft.leader_fortification.fraction_enabled Part of #123847. This commit metamorphically enables the `kv.raft.leader_fortification.fraction_enabled` to exercise raft fortification and leader leases. The commit also includes a few other WIP changes to try to stabilize this. It won't be fully stable until defortification is implemented.
