@fuweid fuweid commented Jul 14, 2024

In commit [1], the newTestKeyIndex function creates one key with two Revision{Main: 14} revisions. However, starting from version [2], etcd server does not allow duplicate keys in a single transaction. This update to newTestKeyIndex is to avoid confusion and ensure consistency with the latest etcd server behavior.

Please read https://github.com/etcd-io/etcd/blob/main/CONTRIBUTING.md#contribution-flow.
