Sorry I come back to a quick question about the bulk loader ... https://www.datastax.com/blog/2018/05/introducing-datastax-bulk-loader
I read this : "Operations such as converting strings to lowercase, arithmetic on input columns, or filtering out rows based on some criteria, are not supported. " Consequently, it's still not possible to use a WHERE clause with DSBulk, right ? I don't really know how I can do it, in order to don't keep the wholeness of business data already stored and which don't need to export... ________________________________ De : adrien ruffie <adriennolar...@hotmail.fr> Envoyé : vendredi 17 janvier 2020 11:39 À : Erick Ramirez <flightc...@gmail.com>; user@cassandra.apache.org <user@cassandra.apache.org> Objet : RE: COPY command with where condition Thank a lot ! It's a good news for DSBulk ! I will take a look around this solution. best regards, Adrian ________________________________ De : Erick Ramirez <flightc...@gmail.com> Envoyé : vendredi 17 janvier 2020 10:02 À : user@cassandra.apache.org <user@cassandra.apache.org> Objet : Re: COPY command with where condition The COPY command doesn't support filtering and it doesn't perform well for large tables. 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
