When I use the command on a regular table It works perfectly, but it is not working when I am doing it on a Materialized View.
COPY person_data (name, id) TO 'test.csv' ;
Column family 'person_data' not found
Whereas the table exists as I can query on it, as the exemple below :
SELECT count(*) from person_data ;
Any idea -or good reasons- why the COPY function does not work on Materialized Views? Is there a dedicated command to do this for MV?
I didn't find any answers searching on the internet. I hope you could help.
NB : I am using Cassandra 3.7 and my cqlsh shows the info : [cqlsh 5.0.1 | Cassandra 3.7 | CQL spec 3.4.2 | Native protocol v4]
