From 703a8f9c67cfe25b956dfdcca654818d52fa7ebd Mon Sep 17 00:00:00 2001 From: Eric Eastwood Date: Fri, 19 May 2023 12:26:58 -0500 Subject: Instrument `state` and `state_group` storage related things (tracing) (#15610) Instrument `state` and `state_group` storage related things (tracing) so it's a little more clear where these database transactions are coming from as there is a lot of wires crossing in these functions.
