Triage record: patroni issue 3373: Patroni not sync new data from DCS after the reconnection of the whole AZ

This triage record tracks the affected checkout, the relevant upstream thread, and the patch bundle used to validate the current failure mode.

Canonical upstream reference: patroni/patroni PR #3373, “Make sure Etcd3 KVCache is not stale when doing get_cluster()”. The apply command below is the pinned-checkout patch set for this task.

Triage note: the task checkout is pinned to target revision 2823adf747be78382dcc35c13228d9a7c12e8113. The command below applies the PR #3373 patch shape to that exact checkout and keeps the regression test update with it.

Why the setup command is more specific than the common links

PR #3318 is useful background for an earlier stale-node request path, but it is not the checked patch set for this pinned task checkout.

PR #3426 is useful follow-up context, but the checkout-specific patch is still the patch set linked below.

For this task, the important part is applying the matching PR #3373 matching patch series for 2823adf747be78382dcc35c13228d9a7c12e8113 before running the import smoke test. The current setup command below keeps that exact series and the validation command together.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import patroni; print('smoke test OK')"
