Etienne Chauchot created BEAM-6591:
--------------------------------------
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
