From 2d710a44af4d2758a0f33703893712693dfaf0af Mon Sep 17 00:00:00 2001 From: Bertrand Drouvot Date: Thu, 7 Nov 2024 12:10:37 +0000 Subject: [PATCH v5 3/4] Don't include other backend's stats in the snapshot When stats_fetch_consistency is set to 'snapshot', don't include other backend's stats in the snapshot.
