Michaël Figuière created CASSANDRA-7789:
-------------------------------------------
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
