> Although the thrift cas call works as expected for dynamic column families, 
> using it on tables with statically defined columns produces unexpected 
> results. The problem, in {{ThriftCASRequest}}, is that while the {{expected}} 
> partition contains a static row, the {{current}} partition has been processed 
> by {{ThriftResultsMerger}} during the read, converting the static columns to 
> clusterings. If {{expected}} contains only a static row, no further checking 
> is carried out, {{appliesTo}} erroneously returns true and the conditional 
> update is performed regardless of the current state of the partition.
