Cassandra: insert in loop

[Boris Poliakovsky]

How to insert in a loop, either in CQL, or UDF?
Please give an example

[Russell Spitzer]

To my knowledge there is not internal looping mechanism in CQL. You have to loop in your client language. 

IE:

for key in keys:
   session.execute_async(statement.bind(key))

Thanks, Rassel,

Unfortunately, I am not familiar with Java

Could you please send me example of CREATE Java UDF command, inside which I can use block "for key in keys:
   session.execute_async(statement.bind(key))"
??

Sincerely,
Boris

[Russell Spitzer]

I know of no way to do it on the server. Like I said the only way I know is from the *client* code. Perhaps you should ask in the Cassandra or Drivers IRC rooms

[Boris Poliakovsky]

I found nou these rooms

Coud you please send me corresponded links ?
