Stefan Miklosovic commented on CASSANDRA-14309:
-----------------------------------------------

Ok, so the behavior will be by default what this ticket is trying to introduce. 
Got it.

I saw your comments on the PR for dtest, I havent looked at it too much 
closely, just refreshed the PR and stuff worked. I might revisit though.

> The current hint system stores a window of hints as defined by 
> {{max_hint_window_in_ms}}, however this window is not persistent across 
> restarts.
> Examples (cluster with RF=3 and 3 nodes, A, B, and C):
>  # A goes down
>  # X ms of hints are stored for A on B and C
>  # A is restarted
>  # A goes down again without hints replaying from B and C
>  # B and C will store up to another {{max_hint_window_in_ms}} of hints for A
>  
>  # A goes down
>  # X ms of hints are stored for A on B and C
>  # B is restarted
>  # B will store up to another {{max_hint_window_in_ms}} of hints for A
>  
> Note that in both these scenarios they can continue forever. If A or B keeps 
> getting restarted hints will continue to pile up.
>  
> Idea of this ticket is to stop this behaviour from happening and only ever 
> store up to {{max_hint_window_in_ms}} of hints for a particular node.
