> I use the following data-model
> column_metadata: []
> name: Customers
> column_type: Super
> gc_grace_seconds: 60
> I have a super-column-family with a single row.
> Within this row I have a single super-column.
> Within this super-column, I concurrently create, read and delete columns.
> I have three threads:
> - Do in a loop: add a column to the super-column.
> - Do in a loop: delete a random column from the super-column.
> - Do in a loop: read the super-column (with all columns).
> After running the above threads concurrently, I always receive one of the following errors:
> ERROR 17:09:57,036 Fatal exception in thread Thread[ReadStage:81,5,main]
