Subject Re: UnsupportedOperationException: Index manager cannot support deleting and inserting into a row in the same mutation
Date Fri, 24 Jun 2011 10:40:59 GMT
"it can cause index corruption IF the row delete timestamp is higher
than the column update's."

By "higher" you mean later, i.e. some modifications to a row, then delete?

I have not seen this error in our logs, but it could happen. I have a
process where I insert historical data into Cassandra, in batches.
Modifying something, then deleting it is a normal scenario.
