Search before asking

• I had searched in the issues and found no similar issues.

Motivation

So that we don't waste time to verify a previous commit - what we're interested in is the latest view.

Solution

Add the following snippet to kvrocks.yaml:

concurrency:
  group: ${{ github.ref }}-${{ github.workflow }}
  cancel-in-progress: true
