Hello.
Thank you for answering the question.

Sorry, let me ask you another question.

In the same environment, set the replication factor to "4" again as follows.
Displayed the trace results of write and read operations at the consistency 
level QUORUM.

> CREATE KEYSPACE test1 WITH REPLICATION = {'class': 'NetworkTopologyStrategy', 
> 'dc1': 4};
> USE test1;
> CREATE TABLE test_table (id int PRIMARY, col1 int, col2 int);
> TRACING on;
> CONSISTENCY quorum;
> INSERT INTO test_table (id, col1, col2) VALUES (2, 2, 2);
> SELECT * FROM test_table;

As a result, in this case both writing and reading
About 40 lines of trace results were displayed.

With a replication factor of "1" and a keyspace of "4" in a four-node cluster
There is a difference in the number of displayed lines in the trace result of 
read operation
Is the operation correct as the specification of the TRACING command?

It would be helpful if you could answer this too.
