Description

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
• avg CSV File R/W MB/s
