I've tried it. It makes them so annoying because of so many same info in these lines if the transaction is large. We could use the connection ID to find the previous log,

connID, s.GetSessionVars().TxnCtx.StartTS, orgStartTS)
if hook := ctx.Value("preCommitHook"); hook != nil {
// For testing purpose.
hook.(func())()
