I would say this guess is true, but maybe not the way you think: the more
disk IO you use for compactions, the
The speed at which compactions operate is also physically restricted by the
speed of the disk. If the disks used on the new node are HDDs, then
increasing the compaction throughput will be of little help. However, if
the disks on the new node are SSDs then increasing the compaction
throughput to
The cassandra version is 3.0.9.
I have changed the heap size (about 32G). Also, the streaming throughput is
set 800MB/sec, and the streaming_socket_timeout_in_ms is default 8640.
I suspect the compactionthroughput has an influence on the new node joining.

You don't mention the version, but here are some general suggestions
- 2 GB heap is very small for a node, especially with 1 TB+ of data.
What is the physical RAM on the host? In general, you want ½ of physical RAM
for the JVM. (Look in jvm.options or cassandra-env.sh)
