Hi people

We are currently moving our second use case from mysql to cassandra. While 
importing the data (ongoing) I noticed that the BloomFilterFalseRation seems to 
be pretty high compared to another CF which is in used in production right now.

Its a hierarchical data model and I cannot avoid to do a read before inserting 
multiple columns.
 
I see a false positive ration of 0.28 while in my other CF it is 0.00025.

The CF has 5 live sstables whiel I read that ratio. At that time I inserted ~ 
200k rows with a total of 1M cols. Row keys are pretty large unfortunately 
(key.length() ~ 60)

Just wanted to check if this value is to be expected. 



Thanks,
Daniel
