I am curious about the need for the ‘waitForApply’ feature. Could you please
explain its purpose? Or maybe I can found it on the design docs?

> WaitForApply on data writes for ratis keys

> Key: HDDS-12247

> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Datanode
> Reporter: Swaminathan Balachandran
> Priority: Major
>
> In order to ensure the data is completely written to at least majority of the
> nodes/all the nodes, a waitForApply where the ratis leader can optionally
> wait for the followers to apply the transaction and just not commit the
> transaction to raft log. This would mean that the applyIndex would have to be
> shared in the raft protocol
