For what it's worth, this turned out to be due to the way Cassandra paginates. It considers the last page reached when the number of returned results is smaller than the page size. If duplicate entries make the last page larger than the page size, pagination never terminates. A 'nodetool scrub' cleared up the duplicate entries. -- Michiel --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
