I've noticed this new feature of 4.0: Streaming optimizations 
(https://cassandra.apache.org/blog/2018/08/07/faster_streaming_in_cassandra.html)
 Is this mean that we could have much more data density with Cassandra 4.0 
(less problems than 3.X)? I mean > 10 TB of data on each node without worrying 
about node join/remove? This is something needed for Write-Heavy applications 
that do not read a lot. When you have like 2 TB of data per day and need to 
keep it for 6 month, it would be waste of money to purchase 180 servers (even 
Commodity or Cloud).  IMHO, even if 4.0 fix problem with streaming/joining a 
new node, still Compaction is another evil for a big node, but we could 
tolerate that somehow Sent using Zoho Mail
