CcrRepository to init follower index (#35719)#37988Conversation
This commit modifies the put follow index action to use a CcrRepository when creating a follower index. It routes the logic through the snapshot/restore process. A wait_for_active_shards parameter can be used to configure how long to wait before returning the response.

@ywelsch I added a pre-6.7 put follow mode. The code is copied from the prior |

Don't you need to set .nodes(true) on the cluster state request in order to get the minNodeVersion? Why is this not failing any tests?

nodes defaults to true. But I will set it explicitly.

Oh well I see that we set clear() which should reset it. I'll investigate why the test did not fail.

The reason that the test was passing (I believe based on reproductions locally) is that the rolling upgrade uses the local cluster as the remote cluster. So the check that your local cluster was mixed with pre-6.7 was pushing us to use compatibility mode. I changed the remote cluster state request to request nodes(true).
This does raise questions about testing, do we need to invest in rolling upgrade tests that use two different cluster and have a test where your local cluster is all 6.7 and the remote cluster is mixed?

👍 too easy to forget about bwc.
Did you notice the ccr tests in rolling upgrade tests fail when this was missing?

Yes. Not always but sometimes.
