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

             Summary: Materialized view is not deleting/updating data when made changes in
base table
                 Key: CASSANDRA-14441
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14441
             Project: Cassandra
          Issue Type: Bug
          Components: Materialized Views
            Reporter: SWAPNIL BALWANT BHISEY
             Fix For: 3.11.x


we have seen issue in mat view for 3.11.1 where mat view

1) we have inserted a row in test table and the same recored is in test_mat table, with Enabled
= true,
2) when I update the same record with Enabled = False, a new row is created in test_mat table(one
with true and one with false) but in test table original record got updated to FALSE.
3) when I delete the record using Feature UUID then only the record with Fales is getting
deleted in both the tables. however I can see the TRUE record in test_mat table.

Issue is not reproducible in 3.11.2
