Brandon Williams commented on CASSANDRA-17763:
----------------------------------------------

Note that we already wait for 2Is to build, so this shouldn't be too difficult.

> Allow node to serve traffic only once compactions settle

> Today when nodes are joined to the cluster, once data streaming is completed, 
> node starts serving traffic, but it's possible there are a lot of pending 
> compactions, so having reads accessing sstables during that time is going to 
> make these reads slower and load the server. In some cases performance is so 
> bad it can bring the application down. 
> Today I overcome this by stopping native transport to a node after join 
> finishes, and enabling it after compactions pending reach a certain 
> threshold, it would be nice to have that as part of the join process, only 
> consider join completed once there are not that many compactions pending.
