> Key: CASSANDRA-6989
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6989
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Cassandra 2.0.6, DataStax Java Driver 2.0.0
> Reporter: Martin Weindel
> Attachments: Main.java
>
>
> See/use the attached Java class to reproduce the problem.
> A table with 200 columns is created. For insertion a prepared statement is
> used which fills nearly all columns with null values.
> After inserting 1000 rows (no update), a "select count(*)" fails with a
> TombstoneOverwhelmingException on server side.
> If the prepared statement contains only the non-null columns, all works fine.
> For me it looks, as if inserting a column cell with null value creates a
> tombstone (but I don't know the internals of Cassandra). If you insert e.g.
> 10000 rows with 11 columns with are null, you already hit the default
> tombstone_failure_threshold.
