That's great! The 3rd point seems exactly what happened on my column
family.
As supposed it was a matter of ignorance :D
Many many thanks

Hi,
I'm using Cassandra 1.1.8 and today I saw in my keyspace a column
family with the following content

So, only rowkeys.
Yesterday those rows were there and I ran some deletions (exactly
on those rows). I'm using Hector
/Mutator<byte []> mutator = HFactory.createMutator(keyspace,
BYTES_ARRAY_SERIALIZER)//
// .addDeletion(challengeRowKey(...),
CHALLENGE_COLUMN_FAMILY_NAME)/
./execute();/
This is a small development and test environment on a single
machine / single node so I don't believe the hardware details are
relevant.
Probably I'm doing something stupid or I didn't get the point
about how things are working, but as far I understood the rows
above are no valid... column name and column value coordinates are
missing so there are no valid cells (rowkey / column name / column
value)...is that right?
I read about ghost reads but I think this is a scenario in a
distribuited environment...is that valid after one day and on a
single Cassandra node??
Regards and thanks in advance,
Andrea
