Thank a lot ! It's a good news for DSBulk ! I will take a look around this solution.

Have you considered the DSBulk tool from DataStax? Previously, it only worked with DataStax Enterprise but a few weeks ago, it was made free and works with open-source Apache Cassandra. For details, see this blogpost<https://www.datastax.com/blog/2019/12/tools-for-apache-cassandra>. Cheers!

We search to use COPY command but I don't find if and how can a WHERE condition can be use ? Because we need to export only several data which must be return by a WHERE closure, specially and unfortunately with ALLOW FILTERING due to several old tables which were poorly conceptualized... Do you know a means to do that please ? Thank all and best regards Adrian
