-----------------------------------------

             Summary: COPY command results in rpc_timeout on large datasets
                 Key: CASSANDRA-7481
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7481
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Jan Penninkhof
            Priority: Critical


When a COPY TO is invoked, all data from a table is dumped to a file. However, if the dataset is relatively large, the underlying query will result in a rpc_timeout. Increasing time-out values in the cassandra.yaml file don't seem to help and also shouldn't be necessary.

It would be good if the COPY TO command would access the database in a paged manner, so that it won't result in an error anymore.
