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

             Summary: CassandraIO split does not work in some corner cases.
                 Key: BEAM-6591
                 URL: https://issues.apache.org/jira/browse/BEAM-6591
             Project: Beam
          Issue Type: Bug
          Components: io-java-cassandra
            Reporter: Etienne Chauchot
            Assignee: Etienne Chauchot


CassandraIO split uses token ranges to split data in the Read part of the IO. 
When one split ends up using the minimum token in the token ring, then the IO 
reads all the data in one split, leading to duplication. This is due to 
behavior of Cassandra: see https://issues.apache.org/jira/browse/CASSANDRA-14684
