Aleksey Yeschenko commented on CASSANDRA-6528:
----------------------------------------------
Example insert query. Do you ever insert, or update set NULL?
> TombstoneOverwhelmingException is thrown while populating data in recently
> truncated CF

> Key: CASSANDRA-6528
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6528
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Cassadra 2.0.3, Linux, 6 nodes
> Reporter: Nikolai Grigoriev
> Priority: Minor
>
> I am running some performance tests and recently I had to flush the data from
> one of the tables and repopulate it. I have about 30M rows with a few columns
> in each, about 5kb per row in in total. In order to repopulate the data I do
> "truncate <table>" from CQLSH and then relaunch the test. The test simply
> inserts the data in the table, does not read anything. Shortly after
> restarting the data generator I see this on one of the nodes:
> {code}
