> While CASSANDRA-7405 is on its way to make the {{COPY}} command much fast=
er, it's still likely to hang for many minutes when transferring a large am=
ount of data.=20
> This gives the feeling to the newcomers that something went wrong. Even i=
f 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
