-------------------------------------------

             Summary: cqlsh COPY Command should display progress
                 Key: CASSANDRA-7789
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7789
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Michaël Figuière
            Priority: Minor


While CASSANDRA-7405 is on its way to make the {{COPY}} command much faster, it's still likely to hang for many minutes when transferring a large amount of data. 

This gives the feeling to the newcomers that something went wrong. Even if the user expect cqlsh to hang for a long moment, it's not very convenient as you have no idea of when the copy will be complete.

I believe it would be very pleasant if the {{COPY}} command could display an in-place progress output while it's executed with probably:
* Rows copied
* avg Rows/s
* CSV File R/W MB
* CSV File R/W MB/s
