             Summary: Harry-found silent data loss issue
                 Key: CASSANDRA-18993
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-18993
             Project: Cassandra
          Issue Type: Bug
            Reporter: Alex Petrov


Harry has discovered a silent data loss bug in trunk, but it goes all the way 
back to appx 4.1.

Some rows are not visble after flush. Compared Harry repro running a memtable 
instead of a regular Harry model, and it still reproduces (in other words, it 
is almost certainly not a Harry issue).

Simple schema, and only one flush is required for repro, so not an unlikely 
bug. Max partition size is 1k rows, so not an unlikely setup here, either. No 
concurrency involved; reproduces stably. Good chance this is related to the 
fact the schema has DESC clusterings.

I am working on posting a Harry branch that stably reproduces it.
