streaming stuck on joining a node with TBs of data

Hi, I'm going to join multiple new nodes to already existed and running cluster. Each node should stream in >2TB of data, and it took a few days (with 500Mb streaming) to almost get finished. But it stuck on streaming-in from one final node, but i can not see any bottleneck on any side (sourc

Re: many instances of org.apache.cassandra.io.sstable.format.SSTableReader$InstanceTidier$1 on the heap

I don't have specific experience relating to InstanceTidier but when I saw this, I immediately thought of repairs blowing up the heap. 40K instances indicates to me that you have thousands of SSTables -- are they tiny (like 1MB or less)? Otherwise, are they dense nodes (~1TB or more)? How do you r
