Jason Harvey commented on CASSANDRA-3820:
-----------------------------------------
Peter: You're right! All zeroes on the end of my largest bloomfilter file.
The affected CF has billions of keys, and the sstable in question is 35GB, so
I'm guessing it is likely over 143 million.
> Columns missing after upgrade from 0.8.5 to 1.0.7.

> After an upgrade, one of our CFs had a lot of rows with missing columns. I've

> A few notes:
> * The rows with missing data were fully restored after scrubbing the sstables.
> * The row which I reproduced on happened to be split across multiple sstables.
> * When I copied the first sstable I found the row on, I was able to 'list'
> rows from the sstable, but any and all 'get' calls failed.
> * These SStables were natively created on 0.8.5; they did not come from any
> previous upgrade.
