Question

I need to do some cassandra for study project.

It’s really simple:

One Column Family, two colums (let’s say ‘name’ and ‘mail’)

Now I wanna insert some data to Cassandra like

‘name’ => ‘Horst’,
‘mail’ => ‘[e-mail]’

Don’t need nothing more – but cassandra needs an sub name for the column family.

columnFamilyName.ABC (
…
)

Is there a way to insert data without this ABC? I only need the columns – nothing more.

Thank’s allot for your help.

Row keys are required and they must be unique — think of them like primary keys in an RDBMS. If you don’t care what they are and you just need them to be unique, you would normally use a UUID. But since you only have two rows, why not just name them ‘a’ and ‘b’?
